Prior to the outburst detection, the last observation (also by CCY) indicated the star was not in outburst less than 24 hours prior (mvis < 13.8 at JD 2456951.6326).
July 16, 2013: Based on your observations, the HST/COS team will be making the final decision tomorrow afternoon (2013 July 17) or the next morning whether to observe the dwarf nova HS 2214+2845 = V513 Peg on:
V513 Peg (HS 2214+2845) 2013 July 18 21:08:59 through July 19 01:04:23 UT
V513 Peg is 16.8V at minimum and 12.5V at maximum. Please monitor V513 Peg closely through July 19.
July 8, 2013: The VY Scl variable OR And continues in its low state, so it has been scheduled for HST/COS observations. Based on your observations, the HST/COS team will be making the final decision tomorrow morning (2013 July 9) whether to observe OR And on:
OR And 2013 July 10 11:47:01 through 15:56:12 UT
OR And is ~18V in its low state and ~14.5V in its high state.
HST/COS is scheduled to observe the SU UMa variable AX For on the next day:
