With V513 Peg behind them, the next HST/COS target in the CV campaign is 1RXS J213807.1+261958 (OT J213806.6+261957), scheduled for 2013 July 25. Please see AAVSO Special Notice #364 for details.
Many thanks and good observing - Elizabeth Waagen, AAVSO HQ
In AAVSO Special Notice #364 I incorrectly stated that 1RXS J213807.1+261958 (OT J213806.6+261957) is the northern of the optical pair separated by 2.5". It is actually the SOUTHERN star and is moving to the northeast. This correction is reported in AAVSO Special Notice #365.
My apologies for the error!
Good observing, Elizabeth
Observations are critical tonight (2013 July 23-24) and tomorrow (July 24-25) for 1RXS J213807.1+261958 (OT J213806.6+261957). The HST team will decide tomorrow whether to observe this target on July 25. Please see AAVSO Special Notices #364 and #365 for details. Also, please observe this target through the night of July 25-26 so we have good coverage through the HST observation window.
Many thanks and good observing - Elizabeth Waagen
