March Meetings

This month’s meeting will be on Friday, March 1, at 8:00 PM in room 215 of the Aerospace Engineering building, on the campus of Auburn University.

This month’s members and friends dark-sky star party will be on Friday/Saturday, March 15/16, at Cliff Hill’s farm.   The Friday date being the primary date Saturday as a fall back in case of clouds on Friday.  Die-hard observers can participate in this year’s Messier Marathon.  The middle of March is the best time to try to observe the entire Messier Catalog in one evening.  The Astronomical League has compiled a handy observing log sorted by the most efficient star hopping route.  Check it out at  http://www.reflector.org/MESSIER.HTM 

On Tuesday, March 19, Jim McLaughlin will be hosting the third annual star party for the science students at St. Bede School, in Montgomery.  If you’ll be able to give Jim a hand, please let him know at ksjtmclaughlin@mindspring.com  Sunset will be at 5:51, so let’s try to be set-up and ready to go by 6:00PM.  St. Bede School is located near the intersection of Atlanta Highway and Perry Hill Rd..  The entrance to the observing field is from Perry Hill Rd. 

Full Moon at Perigee
From: "John B. Zachry"  jbzachry@mindspring.com

This Full Moon (Wednesday, 2/27, 4:17 a.m.) occurs at almost exactly the same time as the closest perigee of the year (3:00 p.m.), which means that it will technically be the largest Full Moon of the year. Perigee refers to the time when the Moon is nearest the Earth, roughly 356,897 km (221,766 miles) in this case." - John
 


Maxwell  Star Party
Submitted by Tom McGowan

On Monday, February 18, club members Russell Whigham, Jim Locke, Mark Brown, Jim McLaughlin, Julie McGowan and Tom McGowan met at Maxwell Air Force Base to treat the residents to a celestial show. Views of Jupiter, Saturn, the Moon and the Orion nebula were enjoyed by all. We had good skies. For many people, this was their first time looking thru "real" telescopes. Everyone was delighted to be able to view such beautiful sights as I had much feedback thru-out the week. They expressed many thanks to the club members for taking the time to share with them. I receive many drawings from the kids as well as letters. Here is a particular letter I wish to include:

"We Really enjoyed "gazing at the stars" last night. It was an experience that Cody and I will never forget. Thank you so much for your time, effort and thoughtfulness--- and for caring so much about our kids in the community! 
                God Bless! 
                        Jem, Sherie and Cody  " 
This is one of the main reasons we should continue to participate in Public Star Parties. Many people don't have the equipment and knowledge to see for themselves but do have the wonder and interest of the heavens. And it is us, the club members, who can make the skies accessible to them. Who knows how we may influence these people-especially the children, to open up a new window of discovery for them. I like to think that their exposure to the skies from a star party will always be in their memories and may be the catalyst for some to further their interest in astronomy. And all it costs us is the time of one evening. 

Many thanks to the club members for contributing their time to make this happen!

I'd like to congratulate Eddie Kirkland on becoming the new owner of a 16-inch F/4.5 MidnighTelescope. I'm sure that will keep Eddie busy for awhile!

Saturn Occultation Images
From: "Mark A. Brown" loneastronomer@knology.net

Here are some photos from the February 20th occultation of Saturn. I was fortunate enough to have the clouds clear out in time so I could capture these shots of Saturn's reappearance on the lit side of the Moon (7:21pm CST). I photographed the occultation using my C8 by means of eyepiece projection with a 25mm eyepiece. The exposure times were two seconds thus the reason for the Moon being overexposed. I used Fuji 400 speed film. By using eyepiece projection, the effective focal length was ~ 27,430mm at a focal ratio of f/135. I've also included a daytime/dusk shot of Saturn about 15 minutes prior to its disappearance. That shot is at prime-focus through the C8. Saturn is just visible to the left of the unlit portion of the Moon. This was the last occultation of Saturn to be seen from this location until February 28, 2037.

New Instrument Package to Expand Hubble Space Telescope's Vision
From: Ron Baalke baalke@zagami.jpl.nasa.gov 

PRESS RELEASE NO.: STScI-PR02-06

NASA's Hubble Space Telescope has been pushing the frontiers of astronomy since its launch in 1990. The orbiting observatory has watched a comet disintegrate as it passed by the Sun and pinpointed a massive star that exploded 10 billion years ago. It has provided a view of a bewildering zoo of young galaxies that existed when the cosmos was a youngster. It has measured the expansion rate of the universe and detected clumps of matter - perhaps the seeds of planets - swirling around nascent stars.

Now its time to expand Hubble's vision even further during Servicing Mission 3B, scheduled to begin Feb. 28 with the launch of the space shuttle Columbia. The mission will give the orbital observatory a series of midlife upgrades that includes the Advanced Camera for Surveys (ACS), a new instrument package that covers twice the area, has twice the sharpness, and is up to five times more sensitive to light than Hubble's workhorse camera, the Wide Field and Planetary Camera 2. The simulated image [right frame] depicts how the cosmos will look through the "eyes" of the ACS. 

More information on the Advanced Camera for Surveys is available at web sites:
