March 17, 2014: HST/COS is scheduled to observe the the U Gem-type dwarf nova
SDSS J100658.40+233724.4 this Thursday. Observations are scheduled for:
SDSS J100658.40+233724.4 2014 March 20 05:35:00 through 14:17:27 UT
The scheduling team will likely make their final decision early WEDNESDAY (March 19), so your observations are essential tonight and tomorrow night.
In the April 2014 Newsletter we published an article on variable stars with close companion causing problems with their photometry.
In this page we give more information and updated tables so you can be aware of the stars that are causing problems or have caused problems in the past.
We will be updating this information with more stars in the future.
If you find a problem similar to those described in the Newsletter article, please let us know.
March 5, 2014: HST/COS are being scheduled for the U Gem-type dwarf nova SDSS J100658.40+233724.4, the 40th and final target of the major CV observing campaign organized in 2012 by Drs. Boris Gaensicke, Joseph Patterson, Arne Henden, and 13 other astronomers (see AAVSO Alert Notice 471 and note below). A precise time will be announced later, but the scheduled HST observing window is:
SDSS J100658.40+233724.4 2014 Mar. 20 or 21 UT (to be determined)

1. Event: Nova Sagittarii 2014 = PNV J18250860-2236024 [V5666 Sgr]
Discovered by: Sigeru Furuyama (Tone-machi, Ibaraki-ken, Japan) and reported by S. Nakano (Sumoto, Japan)
Discovery magnitude: unfiltered CCD magnitude 8.7, using a 200-mm f/2.8 camera lens + BJ-42L camera
Discovery date: 2014 Jan. 26.857 UT
Coordinates: R.A. 18 25 08.60 Decl. = -22 36 02.4 (2000.0)
February 7, 2014
Event: Outburst of the recurrent nova V745 Sco
Discovery by: Rod Stubbings (Tetoora Road, VIC, Australia)
Discovery magnitude: 9.0 (visual)
Discovery date: 2014 February 6.694 UT
Coordinates: R.A. 17 55 22.27 Dec. -33 14 58.5 (2000.0)
February 6, 2014: Rod Stubbings (observer code SRX; Tetoora Road, Victoria, Australia) reports an outburst of the recurrent nova V0745 Sco (aka Nova Sco 1937). Stubbings reports the nova at a visual magnitude of 9.0 on 2014 February 6.694 UT (JD 2456695.194). He previously observed the field on 2014 February 5.696 and found the star fainter than 13.0, indicating that this outburst began within the past 24 hours.
