AAS 30 Year Anniversary

The Auburn Astronomical Society’s 30-year anniversary banquet will be on October 9, 2010, at 6:00PM at Good Ol’ Boy’s restaurant at 1843 Sandhill Road in Auburn (Lee County Road 10), just under 2 miles from US 29 S; 3.5 miles from Society Hill Road.  We’ll order from the menu and an 18% gratuity will be added to your order.  Thanks to Joyce and Rhon Jenkins for making the arrangements. 

Our anniversary banquets have traditionally been family affairs – a time to share a bit of what we do with friends and family.  We also hope that former AAS members will come back for a visit, and perhaps, get back into astronomy. 

The restaurant needs an approximate head count.  If you plan to attend, please let Rhon know how many will be in your party. Rhon also requests that, if you have any newspaper articles or photographs of the clubs history, that you send them to him to be used in his PowerPoint presentation, following the meal.
 
 

New Members 

Please join me in welcoming one returning member and two new members:

Jeff Crawford, from Columbus, goes way back with AAS.  Jeff was a member in 1984, at the dedication of our Moores Meadow Observatory.

Also from Columbus is new member, John Wingard.  John has a 3.5-inch Questar and has been in the hobby for several years. 

Rohan Patel is from Sylacauga, and an is an Auburn University aerospace engineering major.  Rohan is just getting started in hobby, but has had a long time interest in astronomy. 

Welcome all!
 
 

Public Stargazes

Mary Olive Thomas Demonstration Forest 
Moore’s Mill Road, Auburn
September 11, 7:00PM

Jennifer Lolley and the members of her Forest Ecology Preserve group have invited us back to the Mary Olive Thomas Demonstration Forest for a stargaze.   Sunset will be at 6:54 PM, with activities getting underway at 7:00 PM, with telescopic observing about 45 minutes to an hour later.   Amy McKay will be bring some of her older Cub Scouts, as well.  The gate will be open from 5:30 on if you prefer to set up your scope before dark.  Jupiter rise will be at 7:21 in the east.  The 3-day old crescent Moonset will be at  8:51 PM, so we should get to view some of the brighter deep-sky objects, as well. Moon will be in a nice grouping with Mars, Venus, and Spica in the west. 

Please let us know if you can bring your telescope.  I’ll be sending out some suggested deep-sky objects for observing in a day or so.  If you’d like to help, but don’t have a telescope, we’ll need someone to point out the four, 3rd magnitude or brighter satellites.  Check out images of our previous MOTDF stargazes. 

Directions to Mary Olive Thomas Forest

For those familiar with Auburn:  on Moore’s Mill Road, one mile east of the Ogletree Village shopping center ... on the north side of the road.  There will be a sign at the gate.  The shopping center is at the intersection of Moores Mill Road and Ogletree-Hamilton road.  This intersection is east of Dean Road, on Moore’s Mill. 

For those coming from out of town:  take exit 58 off I-85 (Tigertown exit) south (away from Tigertown) on Gateway Drive .  This exit road takes a curve toward the east and, approximately 0.7 miles after you get off the interstate, intersects Society Hill Road (runs north-south).  It's a fairly large intersection, so it'll be hard to miss.   Approximately 3.2 miles later, Society Hill intersects Moores Mill at a flashing red light.  There's a convenience store called the LAZ-B at this intersection.  Turn right on Moores Mill.  The gate will be about 0.9 mile on the right.

SLOOH

Our September program was a continuation of our SLOOH online observatory project.  We began with Allen Screws at the keyboard, followed by Alan Cook, and Michael Pastorett.  After logging on, Allen quickly learned to manipulate the telescope controls one of the many telescopes, located in the Canary Islands, and reserved a time-slot for imaging our first object, Jupiter.  For many of us this was the first time we’d seen a live CCD image appear before our eyes.  Soon, the Great Red Spot was easily visible.  We imaged several objects including planetary nebula NGC 40, Jupiter,  Uranus, and M-74. 

Vocabulary Lesson

Sidereal:  1. Relating to the stars. 2. Measured with reference to the apparent motion of the stars. 
This word appears within two more common words that show our historical interest in the stars. "Desire" literally means "of a star" in the sense of wishing upon a star, while "consider" means "together with a star" and is connected to an older meaning of "observe".
