Professor David Lien, visiting Professor of Astronomy and Physics at Oklahoma State University will be our featured speaker at May's meeting. Professor Lien's research interests are Comets, Interstellar medium, Archeoastronomy and Meteorological optics. His topic at our meeting will be COMETS; a very timely subject since one of the best comets in the past decade, Ikeya-Zhang, is still a naked eye comet gracing our late night skies. Several other comets are increasing in brightness. If the solid nucleuses of all comets are thought to be essentially the same, then why does the appearance of every comet seem to be different? Can we model comets here on Earth to explain the variations that we see? Can Asteroids have tails? These and other questions will be explored and answered by Professor Lien during his presentation and since he has a wide range of research and interests in Astronomy, club members should feel free to ask questions in all aspects of Astronomy.

Professor Lien will be our final speaker until September, as we will be going to our monthly star party meetings at the observatory during the summer months. Our attendance has been 56 to 77 people during the past four months. This is historically good attendance, but it can still increase some more. If you haven't been to a meeting in recent months visit us during our May meeting when we will have an excellent speaker. I like to conduct fast moving meetings with announcements and only essential business. Within a half hour of our meeting's start we present our speaker, and at the end of the meeting we come forward to enjoy refreshments and socialize. I hope to see you there.

Mid-States Regional Astronomical League Convention

Time is running out to register for the Mid-States convention in June. Since Siloam Springs is so close to Tulsa, It may be possible to drive over for the main day on Saturday. Let us know if you are going and perhaps some of you can get together and carpool there. We'd like to get all of us together there and get a picture.

The 2002 Mid-States Regional Convention will be hosted by the Christian Association of Stellar Explorers and will be held June 7-9, 2002 in Siloam Springs, Arkansas on the campus of John Brown University. The club's observing site at New Life Ranch will be open for evening observing sessions at the convention.

MSRAL 2002 is proud to welcome Dr. Derek Sears of the Arkansas-Oklahoma Center for Space and Planetary Sciences as our keynote speaker at dinner on Saturday. Dr. Sears will be speaking on "Hera and Andromeda: New Insights Into the Formation and Evolution of the Solar System." Dr. Sears is also a professor in the Cosmochemistry Group at the University of Arkansas in Fayetteville.

Their web site is It contains more details on the convention and registration forms. Several of our members went to the MidStates convention in 2001. Our club is hosting the convention for 2003 and this will be a great opportunity to get ideas to make our convention a success.

Spectacular Sunset Solar Eclipse

By John Land

June 10, 2002
Starts 7:27 PM
Maximum 8:18 PM About 50% coverage
Sunset 8:37 PM

If the skies are clear, this years eclipse promises to be spectacular. As always you must not look at the sun directly during a solar eclipse.

The safest method is to project the sun's image onto a white card using a small pinhole in a sheet of aluminum foil taped to a larger card. Try several sizes of pinholes spaced an inch or so apart. As sunset approaches you will be able to see the moon's silhouette covering about half the sun. You can look at the sun during the last few minutes before sunset with dark glasses.

BUT DO NOT STARE AT IT FOR A PROLONGED TIME. NEVER use binoculars or telescopes on to look at the sun without using fully tested Full Spectrum Front Surface solar filters.

Full coverage of the eclipse story and safety tips can be found at If its cloudy on eclipse day you'll be able to see lots of images the next day on Check out this site a few days ahead of time for more tips on observing the eclipse.

The show doesn't stop at sunset. Jupiter and Venus are still close together in the evening sky. Venus is the brighter of the two. They have their closest approach on the evenings of June 3rd and 4th.

You can keep up with the summer astronomy events and maybe even join local astronomy enthusiasts from the Astronomy Club of Tulsa. Check out our website:


Comet Iyeka-Zhang

By Gerald R. Miller

While trying out my new SBIG ST10XME for the first time, I had just finished imaging the Sunflower Galaxy (M63) and noticed that Comet Iyeka-Zhang was in a good position to image. So I took 120 unguided exposures of 30 seconds each using my 10" LX200 F. 6.3 scope in Clear, Red, Green and Blue. I then combined them in MaximDL, and processed them in Photoshop to bring out the core. This shot is a mono version of the color shot, that can be found at . It took about an hour to capture the images.
