Astronomical Observing from Silver Springs Campgrounds on Saturday 10/30/2010 at 7:24:43pm (nautical twilight). Sunset: 6:26pm Civil twilight ends: 6:52pm Nautical twilight ends: 7:25pm Astronomical twilight ends: 7:57pm Moon Phase: 45.00% illuminated (waning crescent) Rise: 0:00am Age: 23d 4h 33m since last New Moon
We'll be setting up telescopes at the Silver Springs Campgrounds on Young Rd in Stow in conjunction with the Ohio Society for the Elevation of Kites for the annual Halloween Night Kite Flight at 4:00pm. We had a ball at this event five years ago and again two years ago. We fully expect to do the same this year! The Night Kite Flight folks are great - and always welcome us with enthusiasm exceeded only by the awe expressed by us astronomy folks at the magnificence of their illuminated kites. What?! Astronomers awed by illuminated kites? I'm entirely serious about this, you have to see them to believe it. Come out and share the joy - you won't be disappointed. Food will be available.
This is a "pot luck" event, if you plan on eating, please bring a dish to share. The kites will be set up at the top of the hill at the new open pavilion. All this depends, of course, on the weather. Kites, telescopes and bad weather don't mix.
Tonight, we'll have no Moon until it rises after 1:00am Sunday morning. This will be a great night for observing those faint DSOs (Deep Space Objects). We'll have the colorful double stars, open clusters made up of hundreds of stars, the globular clusters comprised of hundreds of thousands of stars, planetary nebula formed by dying stars, diffuse nebula and emission nebula where stars are being born. Galaxies, including M31 - the Andromeda Galaxy - our closest neighboring island universe - will be ours for the asking - and now it's rising early enough to see without having to wait. Bring binoculars if you have a pair and we'll show you how to find the Andromeda Galaxy with them! Also, we'll show you how to find the beautiful "Coat Hanger" cluster which is best seen in binoculars.

We hope to see you here for a night under the stars - now in our sixteenth year!

On 10/30/2010 at 7:24:43pm Mars will be 0.7° above the southwest horizon Question: Will Mars be "as big as a Full Moon on August 27!" ??? Answer: ABSOLUTELY NOT!!! Question: Will there be "Two Full Moons in the Sky!" ??? Answer: ABSOLUTELY NOT!!! Mars was the closest in recorded history on August 27, but that was only in 2003, not every year! At that time, it appeared to be 1/75th the apparent diameter of the Moon! NOT the "same size as the Full Moon".
