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
