SBS 1017+533 多分スーパーです。非常によい観測条件です(天候を除けば・・) As reported by Gary Poyner, the SU UMa-type dwarf nova SBS 1017+533 is undergoing a likely superoutburst. The last superoutburst was reported in 2000 September-October, which was not well observed because of the poor location in the sky. The current outburst seems to provide an excellent opportunity to study this dwarf nova in detail. Follow-up time-resolved photometry is strongly recommended.
