Congratulations to our colleague and sister observatory in the Pacific,
Mr. Jim Phillips
and Pacific Sky Observatory.
Below, find the abstract from research done at that observatory in 2004, and presented at the Winter 2005 meeting of the American Astronomical Society, held in California this week.
AAS 205th Meeting, 9-13 January 2005
Session 54 Pulsating Stars: RR Lyraes, Miras, Cepheids, etc.
Poster, Tuesday, January 11, 2005, 9:20am-6:30pm, Exhibit Hall

[54.04] AH Leo and the Blazhko Effect
J. Phillips (Swinburne Astronomy Online), P.L. Gay (Harvard University)
We obtained 563 V-Band observations of AH Leo between January 27 and May 12, 2004. All observations were obtained with a 12-inch Schmidt-Cassegrain located on the island of Saipan, in the Commonwealth of the Northern Mariana Islands. We show that AH Leo is a type RRab RR Lyrae star with a minimum magnitude of V=14.658 magnitudes, a maximum amplitude of 0.989 magnitudes and a minimum amplitude of perhaps just 0.4 magnitudes. Its primary period is 0.4662609 days. Our observations also confirm the presence of the Blazhko effect, which had previously been detected by Smith and Gay (private communication) in 1993 and 1994. We estimate the Blazhko period to be roughly 20-days, however poor phase coverage at maximum light makes exact determination impossible. We also note that the bump during minimum, which is common in many RR Lyraes, varied throughout the Blazhko cycle, demonstrating amplitudes between 0 and 0.15 magnitudes.
We would like to thank Sarah Maddison and Swinburne Astronomy Online for supporting this project

Yes, congratulations!
Now if I only had a clue what that abstract meant.
Way too technical for my little ole brain.

Congrats to those at the Observatory!
Hmmm, that gives me a few ideas, Guam and Saipan are only about a 2 hour flight from here, maybe I could rent a place and put a scope there.
Sure would beat banging my head against the wall with the atmospheric seeing we have here....
