Hi Everyone,

I'm just back from a few nights up at Cherry Springs. Last Saturday I was checking the national weather service for Cherry Springs and I saw it was going to be clear and in the high 80's during the day. I hadn't been able to get up to Cherry Springs at all yet this year so this looked like a good opportunity. My bags and scope was packed and I was off by noon time Sunday. I got up there around 6 and set up camp. While I was cooking supper a few people stopped by and asked if I was an astronomer and when I answers yes they asked if they could come back after dark. I told them that the gate will be closed and locked but they could park across the street and walk in, they would certainly be welcomed. Just as I figured, with a moon one day pass full, I was the only astronomer on the field. As it got dark I set up my trusty Meade NGC60 F11 telescope. Right after I closed the gate that's when people started to arrive. Not just a few, about 15-20 people showed up, o boy this is going to be a full blown star party. They were laying down blankets and setting up lawn chairs all around me and here I am with just a little 60. The sky hadn't gotten dark yet but Venus was certainly making it presents known so that was the first target for the night. By the time everyone looked at that the sky had darken quit nicely so I started pointing out all the different constellation. Was wishing I had my green laser with me but I wasn't counting on showing the sky to anyone and besides you aren't allowed to use one on the field though there wasn't anyone around to object. Along with showing each constellation I told them the Greek Mythology about the stars along with some Indian lore thrown in. By the time I was done with that the sky had completely darken. It was the best sky I had seen all year. The milky way was a bright silver band across the sky. Most people were in awl, they had never seen the milky way. The rift really stood out and I explained to them that that was not a division in the milky way but a dark gas cloud in front of it. It was time to get to the telescope. I started with M4 over in Scorpius, at home this would be a faint fuzzy but here at Cherry Spring in shown very bright in my little telescope. People got really excited with this so I went to M80 before proceeding over to Sagittarius, we took in all the Messieurs in this constellation and even the small globs like M54, 70 and 69 were seen good with direct vision. Not a single person said they couldn't see what I had the telescope pointed at. As it got about 10:30 the sky was still screaming. We proceed east through M55 and M75 to Capricornus where we took in M30, 73 and 72. I had really excepted most of the people would have left by now but it still looked like the same number. The whole time I was hit with all kinds of questions from how do we tell one fuzzy from another, how stars and planets form and die to UFO's. Glad I had a gallon of water near by. We proceeded up to M11 and 26 when I saw Jupiter had come up over the trees. I could see a very bright Moon through the trees but it hadn't yet affected the sky all that much. We went for Jupiter, it was the best I'd seen in ages, never looked at it from Cherry Spring and guess what, the red spot was visible, what timing!! I remembered Uranus was near by and the the people were thrilled that they got to see 3 planets that night. By the time we finished with those planets the moon had popped up over the tree's so we finished off the night with the bright Orb. I didn't think a dark site would make much different with lunar observing but I was wrong. When I started looked at the moon the site nearly knocked my socks off. What sharp detail, I wish I had brought some of my higher power eyepieces but I only had a 10 because had only planed on looking at deep sky objects. By far, the moon was everyone's favorite site for the night though I did hear a lot of good commits about a number of deep sky objects. It is now getting 1 in the morning and I'm wanting to say, “Hey, haven't you got to get home?” When I told the people that the moon had bright the sky and there wouldn't be able to see too many more objects that when they began to leave. A number of people want to know when I was next going to be back up here at Cherry Springs, they wanted to know so they could plan there vacations to coincide when I am here, I really didn't know what to say so I started handing out my astronomy business card for the Brandywine Stargazers. By the time the crowd left the sky was reduced to about mag 3. Now was a little time to myself, I was glad I had this little scope with the computerized push too because there weren't much guide stars to go by but with a very bright moon over my back shoulder, with the aid of the computer system I was able to finish out the night viewing M57, 56, 27 and M71. I was surprise that even with such a bright moon lighting up the field that I was still able to see these faint globs. I finely called it a night at 2:30. I had a list as long as my arm of new objects I wanted to go for but never got the chance. O well there is tomorrow night. Monday night saw more people. I went though the same thing as Sunday night. I asked the people how they know about this place beings some were from Baltimore, others from Ohio and New York, Cherry Springs had been featured in a number of publications including National Geographic. Now everyone taking a vacation down Route 6 in Pennsylvania has got to stop off at Cherry Springs. The general public doesn't know there won't probably be any astronomer on the field during a bright moon, they don't know the meaning of a dark window and that most astronomers with big scopes seem to think their telescope will melt or explode if exposed to moon light. Let me tell you, I'll never have second douts about heading to Cherry Springs with a day old full moon, matter of fact it was nice being the “King Of the Mountain”. Just set up close to the trees so the moon will be blocked out as long as possible. I stayed on thought Tuesday night and left Wednesday morning. Yes I had some people on Tuesday night too. Never did get to that list, o well, next time.

The zodiacal light, or the false dawn, is visible about two hours before sunrise from a dark site during the latter part of September.

A normally minor meteor shower, the Alpha Aurigids (5 per hour), peaks on the morning of September 1. However, this shower produced an outburst of 130 meteors per hour in 2007.

The Moon is 21.9 days old and is located in Taurus on September 1 at 0:00 UT. The Moon occults Venus on September 11. Browse http://www.lunar-occultations.com/iota/ for additional information on this occultation. The Moon is at its greatest northern declination on September 2 (24.7 degrees) and September 29 (24.5 degrees) and its greatest southern declination on September 15 (-24.7 degrees). Longitudinal libration is at a maximum of 8.0 degrees on September 14 and a minimum of -7.3 degrees on September 2 and -6.6 degrees on September 30. Latitudinal libration is at a maximum of 6.6 degrees on September 9 and a minimum of -6.5 degrees on September 24. Visit http://www.astronomyblogs.com/member/saberscorpx/?xjMsgID=50821 for tips on spotting extreme crescent Moons. Times and dates for the lunar light rays predicted to occur this month are available at http://www.lunar-occultations.com/rlo/rays/rays.htm

The Sun is located in Leo on September 1. It crosses the celestial equator from north to south on September 23, the date of the autumnal equinox.

Brightness, apparent size, illumination, distance from the Earth in astronomical units, and location data for the planets and Pluto on September 1: Mercury (4.6 magnitude, 10.7", 2% illuminated, 0.63 a.u., Sextans), Venus (-4.6 magnitude, 28.3", 42% illuminated, 0.59 a.u., Virgo), Mars (1.5 magnitude, 4.4", 95% illuminated, 2.15 a.u., Virgo), Jupiter (-2.9 magnitude, 49.1", 100% illuminated, 4.01 a.u., Pisces), Saturn (1.0 magnitude, 15.9", 100% illuminated, 10.45 a.u., Virgo), Uranus (5.7 magnitude, 3.7", 100% illuminated, 19.15 a.u., Pisces), Neptune (7.8 magnitude, 2.3", 100% illuminated, 29.03 a.u., Capricornus), and Pluto (14.1 magnitude, 0.1", 100% illuminated, 31.46 a.u., Sagittarius).

This month Venus is located in the southwest, Mars and Saturn in the west, and Jupiter and Uranus in the east during the evening. Jupiter and Uranus lie in the southeastern sky and Neptune is in the south at midnight. Mercury, Jupiter, and Uranus are in the east in the morning.

At midmonth, Mercury is visible during morning twilight, Venus sets at 9:00 p.m. EDT, Mars sets at 9:00 p.m. EDT, Jupiter and Uranus are visible for the entire night, and Saturn sets before 8:00 p.m. EDT for observers at latitude 40 degrees north.

Mercury is in inferior conjunction on September 3. It undergoes its best morning apparition of 2010 during the second half of September. From September 11 to September 16, Mercury increases in magnitude from 2.0 to 0.2, while growing in illumination and shrinking in apparent size. On September 13, it should be visible 5.5 degrees below the first-magnitude star Regulus. Mercury brightens to magnitude -0.4 on September 19, when it reaches greatest western elongation. By the end of the month, Mercury shines at magnitude -1.1 and has only half the apparent diameter that it had on September 1.

On the evening of September 1, the first-magnitude star Spica lies 1.3 degrees from Venus and 3.3 degrees from Mars. Venus shines some three hundred times brighter than Mars. This astronomical trio persists through September 3, after which the three bodies will no longer fit into a five degree circle.
During September, Venus increases in apparent size but decreases in phase. Venus attains maximum brightness on September 23.

The gap between Mars and Venus increases from four to seven degrees during September. From September 4 to September 6, Mars and Spica are a bit more than two degrees apart. The Red Planet exits Virgo and enters Libra near the end of September. By month’s end, Mars subtends only 4.2 arc seconds.

Jupiter passes 1.7 degrees south of the point of the vernal equinox on September 14. Jupiter and Uranus are closest to the Earth on September 20. (Jupiter is nearer to the Earth on September 20 than any time between 1963 and 2022.) The two planets reach opposition within five hours of each other on September 21, when Jupiter and Uranus will be located two degrees and one degree south of the celestial equator respectively. Jupiter will be almost 3,000 times brighter than Uranus. At local midnight, the two gas giants lie more than halfway to the zenith. Callisto undergoes its last shadow transit and last eclipse until 2013 on September 15 and September 23 respectively. When Jupiter is at opposition on September 21, Io and its shadow transit the planet simultaneously starting at 4:42 a.m. EDT. The four Galilean satellites all lie to the east of Jupiter on the morning of September 24. Io is closest, followed by Europa, Callisto, and Ganymede. E. E. Barnard discovered Jupiter’s fifth satellite, fourteenth-magnitude Amalthea, using the 36-inch refractor at the Lick Observatory on September 9, 1892. Browse http://skyandtelescope.com/observing/objects/planets/article_107_1.asp to determine transits of the central meridian by the Great Red Spot. Data on the Galilean satellites is available at http://skytonight.com/observing/objects/javascript/3307071.html#

Saturn sets one hour after the sun on September 1. The Ringed Planet crosses south of the celestial equator on September 8. It will remain there for the next 15 years. Saturn’s fourteenth-magnitude satellite Hyperion was discovered by William Bond on September 19, 1848.

Uranus shines at magnitude 5.7 when it reaches opposition on September 21and can be seen without optical aid from a dark site. Jupiter and Uranus are less than 1.5 degrees apart for most of the month. On September 18, the two gas giants are separated by only 0.8 degree.

Neptune is situated 0.7 degree northeast of the fifth-magnitude star Mu Capricorni and 3.5 degrees northeast of the third-magnitude star Delta Capricorni at mid-month. The eighth planet was discovered by Johann Gottfried Galle on September 23, 1846, using Urbain Le Verrier’s calculations of its position.

Finder charts for Uranus and Neptune are posted at http://media.skyandtelescope.com/documents/Uranus_Neptune_2010.pdf

Pluto lies near an eighth-magnitude star that’s located 2.6 degrees north of the fourth-magnitude star Mu Sagittarii. The dwarf planet culminates just after nightfall. A finder chart is available on page 60 of the July 2010 issue of Sky & Telescope and online at http://www.skyandtelescope.com/skytel/beyondthepage/89002802.html

During September, the periodic comet 103P/Hartley glides northeastward through Lacerta and Cassiopeia. The short-period comet may brighten to tenth-magnitude by late September. Comet 103P/Hartley passes just north of R Cassiopeiae on September 24 and very close to Lambda Cassiopeia on September 29. Comet 10P/Tempel travels southwestward through Cetus. Another possible cometary target is Comet C/2009 K5 (McNaught) in Lynx. Browse http://cometchasing.skyhound.com/ and http://www.aerith.net/comet/future-n.html for additional information on these and other comets.

Asteroid 6 Hebe passes southwestward through Cetus this month. This Main Belt asteroid, which was discovered in 1847 by the amateur astronomer Karl Hencke, is positioned several degrees to the west of Beta Ceti on September 17. Hebe shines at magnitude 7.7 when it reaches opposition on September 21, the same day that Jupiter and Uranus are at opposition. Asteroids 8 Flora and 39 Laetitia also reach opposition this month. Karl Harding discovered asteroid 3 Juno on September 1, 1804. Information on asteroid occultations of stars can be found at http://www.poyntsource.com/New/Global.htm

Is anybody game for a trip to DS3 or DS4 tonight?

Dave

To All: I was feeling the "evil" effects of lunacy, and risked my eyesight tonight observing with Sol Invictus upon 'da Moon! Though I admit, I first did some extended Jovian gymnastics, watching the transit of the GRS followed by Io's shadow transit. The best views tonight were with the 14mm Denkemeir or the 16mm Brandon, using an 80A filter. I also tried a 10mm Ethos, a 12.5mm UO OPS ortho (now rare, for planetary and lunar observing having a custom contrast-enhancing coating), and the 14mm TMB SuperMono.

Enjoy the lunar snapshot(s), I'll post more later. Can you identify Plato, Hyginus, Copernicus, and Triesnecker?

Gastronaut

Is anyone interested in going to DS3 or DS4 tonight?

I went to the Naylor Observatory last night (and the night before) and had some excellent views of Io disappearing into eclipse and the GRS through the 17" classical Cassegrain. If nobody is planning on observing anywhere "nearby", I'll probably go there again tonight.

Dave

Call me obsessive but I can't help myself with this run of good skies and now with a hurricane due to hit NC on Thursday, anything can happen after that.

So, normally, I might pick the BMV for tonight but with DS1 down, the CSC at Coyle Field is once again far too tempting for my mileage.

Moonrise is 10:05PM. Last night Lionel and I had very favorable conditions at Coyle for DSOs before the Moon washed out the Milky Way for about an hour and half or more, so we should get at least 2 hours in tonight before the Moon shows.

Some entertaining Jovian events:
GRS transit at 10:17PM
10:58 PM, Io's shadow begins to cross Jupiter.
11:32 PM, Io begins transit of Jupiter.
1:14 AM, Io's shadow leaves Jupiter's disk.
1:46 AM, Io ends transit of Jupiter.
1:46 AM, Ganymede enters eclipse by Jupiter's shadow.

I'm aiming for a 7:45 PM arrival. Please, post if there's any interest.

Just got this e-mail from DVAA observing chair Al Lamperti:

...

French Creek Gamelands is still closed for maintenance as per a
telephone call this morning and as per web site. It is scheduled to be
closed until September 17th. However, if it opens sooner, the web site
will indicate such. Right now the web site says closed until the above
mentioned date. Current status can be obtained by checking the bottom
of the page at:

Excuse my rookie enthusiasm but the skies were too clear tonight to pass up. Figured I would concentrate on bright objects since the moon was going to dominate the heavens. Took the SCT out to the back yard and was wowed by Jupiter. First time for I ever saw the GRS and as a bonus, saw Europa's shadow transiting the planet about 90 degrees east of the GSR. The clouds bands stood out very well and details were visible within those bands, especially the NEB. I also could detect the orbs of Ganymede and Callisto along with a yellowish coloring to each. Checked out Uranus and Neptune as well a few Messiers. Nothing was as impressive, to me, as the Jupiter show.

I know you DSO aficionados with the BIG light buckets are probably getting a laugh at this. I'm just so pumped up. Figured I had to post or else I would wake up the rest of the family to share my experience.

Dan

Nope, not really. I just don't think I can sit back and watch those precious clear moonless hours go by without observing. I'm thinking of a local trip, with short travel time, but relatively dark skies. Either tonight or Saturday night. With mountains and trees to the east, we should be able to get about 1+ hours of good dso observing tonight and about 1 1/2 hours tomorrow night... at least!

Anybody interested?

Don't everybody post at once.
