January 28, 2006

SUBJECT: Possible New Nova/Dwarf Nova in Hya

Grzegorz Pojmanski, Warsaw University Astronomical Observatory, reports on a possible new nova or dwarf nova discovered by the ASAS3V instrument. The previously unobserved object was first detected by ASAS3V at RA = 10h 25m 22s DEC = -15d 42'.4 (assumed J2000) on Jan 26.245 UT at magnitude 12.219 in V.

Alert Notice 336: CCD campaign to observe 1059+23 AH Leo

April 4, 2006

Subject: CCD CAMPAIGN TO OBSERVE 1059+23 AH LEO

Coordinates: 11:05:05.30 +23:21:08.0 (2000.0)

AAVSO Council member Dr. Pamela Gay, Harvard University, has requested our assistance in observing the RR Lyrae variable star AH Leo closely this spring and early summer. She is studying the Blazhko cycle and other periodicities in this star, and precise, well time-sampled observations are essential.

Alert Notice 339: Far Ultraviolet Spectroscopic Explorer Cataclysmic Variable Survey AND Preliminary NGC 6811 Deep and Wide Field Campaign Announcement

July 6, 2006

1. FAR ULTRAVIOLET SPECTROSCOPIC EXPLORER (FUSE) CATACLYSMIC VARIABLE SURVEY

Dr. Patrick Godon (Villanova University) has requested help for a campaign to observe cataclysmic variables with the orbiting FUSE observatory. The goals of these observations are to help schedule the FUSE observing time and to obtain time series optical data simultaneously with the FUSE observations for correlation of the optical and ultraviolet data.
