November 13, 2012: The HST COS far ultraviolet observations of the WZ Sge-type cataclysmic variable FL Psc (ASAS J002511+1217.2) will be taking place 2012 November 15 22:48:37 UT through November 16 04:49:58 UT (AAVSO Special Notice #305  www.aavso.org/aavso-special-notice-305 ).
***Your observations from TONIGHT and TOMORROW are crucial to confirm whether the target is at minimum (which it must be for HST to observe it). Of course, observing while the satellite observations are taking place and for a few days afterwards are also crucial.***
As instructed in AAVSO Alert Notice 471  (www.aavso.org/aavso-alert-notice-471 ), for CCD observers, simultaneous photometry [shortly before, during, and after the HST
observations] would be ideal. B filter would be best for a light curve, although for the magnitude estimates, a V measurement would be best. An uninterrupted light curve would be better than cycling between filters. This target is likely too faint for positive
visual observations (17.5V at minimum, 10.5V at maximum), but if possible they are welcome, as are visual fainter-than observations fainter than magnitude 15.0.
Coordinates for FL Psc: R.A. 00 25 11.14 Dec +12 17 12.1 (2000.0)
Charts for FL Psc may be created using VSP  (www.aavso.org/vsp ).
Please report observations promptly to the AAVSO International Database using the name FL PSC. If you see the target in outburst, please contact the AAVSO immediately and post a message to the Observations and Campaigns & Observations Reports forum  (www.aavso.org/forum ).
Thank you for your contributions and good observing.
