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

July 6, 2006


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.

Alert Notice 341: NGC 6811 Deep and Wide Field Campaign

Alert Notice 367: Monitoring of the Recurrent Nova U Scorpii

January 22, 2008: Dr. Bradley E. Schaefer (Louisiana State University) requests increased monitoring of the recurrent nova U Scorpii (AAVSO 1616-17) over the next 24 months. Observers are asked to add U Sco to their regular observing program and to monitor the star in advance of an outburst predicted to occur around 2009.3 +/- 1.0 year.
