To avoid possible holiday conflicts, we will slip this month's meeting
back one week to Friday, July 10, at 8:00 PM in room 215 of the Aerospace
Engineering building. Anyone wishing to ride over to the meeting from the
Montgomery area should meet at my house. We'll leave for Auburn at 7:00
PM. The June 20 star party was stormed-out. This month's will be on Saturday,
July 25, at Holley's Field.
If you've been hoping for something a little out-of-the-ordinary, our June meeting certainly filled the bill. As you may remember, the afternoon of the meeting brought some pretty rough weather. Ron Hatherley called to be sure everything was still on for the meeting. The two of us had seen a few limbs down but nothing worse, so we, along with Robert Rock decided to head for Auburn. Jim McLaughlin called just before we left to say that he had some minor roof damage and thought he'd better stick close to home just in case there was more bad weather to follow.
We noticed several signs along the interstate had been blown over. As we exited I-85 heading toward the campus, it was obvious that the weather had taken a greater toll there -- more trees and power lines down. Traffic lights were out until we reached the campus.
As we approached the meeting room we were surprised to find it locked. John Shaw, Marty Skelton, Allan Cook, Allen & Christy Screws waited with Ron, Robert and I, until about 8:20 PM, then left a note and reconvened at the McDonalds across the street.
After returning home, I e-mailed John Zachry and Rhon Jenkins:
Sorry you couldn't make it to the meeting last night -- we assumed due to the severe weather/power outages etc. Those of us who did so up adjourned to McDonalds and resumed our visit. I didn't know until after I returned to Montgomery the extent of the damage in Auburn. My son, John, said a car was blown over just down the street from him and several homes damaged. John Shaw walked to the meeting because of a felled tree across Payne St. Power was out except for the campus and the central business district. Power was still out at the rest stop and dog track on our way back.
I hope you two escaped unscathed.
In summary, we're fine, and I do apologize for not remembering.
For those of you who haven't received this message from Carole, and as a reminder for those who did:
You will receive a more formal invitation through E-mail but, wanted you all to know that famed astro-photographer David Malin will be speaking at the Center on Wed., August 5th,7:00 p.m. EDT . His topic is: "A Universe of Colour". We have room for 120 folks and the tickets will be $5/person. You are receiving first notification and we will accept reservations if you care to purchase your tickets now. The invitations will go out around mid July unless we decide to send them sooner.
Look forward to hearing from you.

Astro Chat Group
Recently, I have set up a place where Online Astronomers can meet. Itís the Online Astronomerís Meeting Hall at http://www.pcola.gulf.net/~johnhall/observat.htm . Its purpose is to provide a place where amateur astronomers on the Internet can have a specific place to schedule meetings online!
Currently, only one meeting is scheduled: The Online Astronomerís General Chat which meets every first Saturday of the Month at 8pm (CST). Mark it down on your calendars, and join me this Saturday! But, like I said, this is ONLY one meeting! I would love to find other astronomers online that would be willing to moderate and/or participate in specific groups including: ATM Astro-photography Questions and Answers Even work to build up a Virtual Online Astronomy Club!
If this sounds like something you might either want to join in, or even help out periodically, drop me a note. The Online Astronomer can only be successful if others, like you, join in!

Want to have your name travel to an comet? For Stardustís 7-year, 3.1-billion-mile journey, solar panels will power the spacecraft to encounter Wild 2, a comet that altered course in 1974 after a close encounter with Jupiter. Now instead of circling among the outer planets in our solar system, Wild 2 (pronounced vihlt 2) travels among the inner planets. It was discovered in 1978 during its first close approach to Earth. Names are being collected at http://stardust.jpl.nasa.gov/microchip
Blinded by the Light

New Scientist June 20, 98
London, Brussels, Seattle and Kiev will be just some of the cities lit up from space in November if an ambitious Russian experiment goes to plan.
A consortium of aerospace companies intends to launch a giant mirror that will reflect sunlight down to Earth, appearing up to ten times as bright as the full Moon. The experiment, called Znamya 2·5, is the brainchild of the Space Regatta Consortium (SRC). The companies involved, led by Energia of Korolev, near Moscow, hope that a successful test will drum up interest in their plan to use up to 200 such reflectors to bring sunlight to the Arctic during the dark days of winter.
Astronomers are aghast. If the idea catches on, they say, it could spell the end of ground-based astronomy by dazzling their telescopes. "I cringe to think that we could lose the night sky because of all these companies with their brain-dead ideas," says Daniel Green, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts.
In August, a routine Progress supply mission will fly to the ageing Mir space station. As usual, the craft will remain docked to Mir for several weeks while it is filled with rubbish. It will then descend into the atmosphere and burn up.
Before its demise, however, the Progress vehicle should on 9 November spin to unfurl a 25-metre reflector made from aluminised Mylar, mounted on the craft's nose. Over the following 24 hours it will complete 16 orbits of the Earth while the crew aboard Mir use a joystick to direct its reflected light onto northern hemisphere cities (see Map).
A similar experiment took place in February 1993 (Technology, print edition, 3 October 1992, p 19). This mirror measured 20 meters across, and was ONLY as bright as the full Moon, because the reflecting surface did not form a complete disc. It also could not be controlled remotely. "We want to test a new shape of the reflector and the ability to control the structure," says Chris Faranetta, deputy managing director of Energia's US office near Washington DC.
Znamya 2·5 should be between five and ten times as bright as its predecessor. If it fulfils its promise, the SRC will seek financial backing for another experiment with a reflector 70 meters across, providing light up to 100 times as bright as the full Moon.
Eventually the SRC would like to launch a constellation of up to 200 reflectors to light up the Arctic. Faranetta admits that rocket launch costs would have to fall substantially before this becomes an economic alternative to building power stations. If the economics do change, however, astronomers would be in serious trouble. Those who are interested in very faint objects must already abandon observations when there is a full Moon. The SRC's plans could put them out of business altogether.
Derek McNally of University College London, who campaigns against "light pollution", says that previous plans to launch reflectors to mark historic events or to launch orbiting adverts have failed, largely due to the reluctance of space agencies to get involved. "But sooner or later someone is going to succeed and then astronomers can pack up their tents and go home," he says.

DUSTIN SMITH'S ASTRONOMY OBSERVATION LOG
[Editor's note: Dustin is saving to buy
a 8-inch Dobsonian. While his bank account grows, he's observing
with what he has -- his binoculars. The
following should serve as an inspiration to those of us who have assumed a jaded and complacent attitude toward our observing. RDW]
Tonight was my first *real* observing session. I used SkyMap to print maps of each cardinal direction, and climbed up onto our roof. I don't know the constellations as of now, so I had to use the "star hopping" technique to find objects. I started in the southern sky, and used the map to locate M7, an open cluster at magnitude 3.3. The next planned object to find was the Butterfly Cluster, another open cluster at magnitude 4.2. To my surprise, both clusters were in the same field of view through the binoculars, so I was able to view both objects at the same time. I then continued my search, my next target was the Lagoon Nebula, at magnitude 5.0. After searching for a few minutes, I eventually found a small patch of gray light, but I'm not sure if it was really the Lagoon Nebula, or one of the other dozen objects in the same region on the map. But who cares? All that matters is that I found my first two astronomical bodies using a star map.
Objects found: M7 - Open Cluster -
Butterfly Cluster - Open Cluster - 4.2
12:30am - Created a makeshift night
flash light by taping yellow plastic to the end of my
father's MagLite flash light. Not very pretty, but it works.
12:44am - Located M4 (My first globular cluster!)
12:50am - Tried to locate M80 (globular cluster, 7.2), unsuccessful.
01:01am - Located the Lagoon Nebula, Trifid Nebula, M21, and M23.
01:08am - Located many small gray patches of light northeast of the Trifid Nebula, but could not determine which objects were which. Possible matches (according to the map) are M18, M24, Omega Nebula, or M16.
01:08am - Located M25.
01:13am - Attempted to locate M28 (globular cluster, 6.9) and M22 (open cluster, 5.1), but could only resolve M22. Globular clusters are by far the hardest objects to detect with my binoculars thus far.
01:24am - Saw a small meteor near the Zenith.
01:25am-01:39am - Looked around in the clouds of the Milky Way, for no particular object.
01:40am - Due to lightening and heavy due, I ended the session.
Lagoon Nebula - 5.0 M22 - Globular Cluster - 5.1
Trifid Nebula - 6.3 M23 - Open Cluster - 5.5
M4 - Globular Cluster - 5.9 M25 - Open Cluster - 4.6
M21 - Open Cluster - 5.9

The other night I took my first shots of the Moon with Jupiter just to the left. I used Kodak T 400 B/W. I am anxious to see if any of the exposures turned out half way decent. I have dusted off an old Tasco tripod from years past and am attempting to use it to manually guide the camera. I am doubtful if it will work. I may try my hand at building a double arm barnyard door mount and purchasing a telephoto for the OM-1. I would rather sweet talk my wife into a SCT. :-)
S. Nakano, Sugano, Japan, reports the discovery of a possible nova (mag 9.5) by Kesao Takamizawa, Saku-machi, Nagano-ken, which was found on two T-Max 400 films (each exposure about 4.5 min) taken on June 15.561 UT with a 0.10-m f/4.0 lens. Takamizawa reports the position of the possible nova as R.A. = 17h32m00s.0, Decl. = -19o13'56" (equinox 2000.0). No star is present at this location on 48 previous patrol films taken by Takamizawa between 1994 Feb. 17 and 1998 May 19. R. and Y. Kushida report the following position end figures for the variable star from a poor CCD image obtained on June 16.531, when they estimated V = 10.0: 31m59s.82, 57".0 (uncertainty stated as 1" or more; average of three frames). There is a red USNO A1.0 star (B = 18.0, R = 16.8) at position end figures 59s.79, 55".0. T. Kato, Kyoto University, notes that the possible nova lies within the 16" error circle of the ROSAT source 1RXS 173200.0-191349.
Hope to see everyone at the meeting NEXT Friday,
