Alert Notice 838: Monitoring requested for 11 dwarf novae in support of HST observations in 2023-2024 (backup copy)

Notes: LL Lyr was not observed in July 2024 due to technical issues with HST, but it may be observed in August so please continue observations. Also, CS Ind is planned to be observed in August 2024, so please observe it. More information on CS Ind's and LL Lyr's schedules will be issued when available. - Elizabeth O. Waagen, August 4, 2024

KZ Gem has been put on hold by HST, and likely won't be observed until next year, if at all.  -  Elizabeth O. Waagen, January 2, 2024

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.
