ID Henden AAVSO Goranskij & Shugarov 1 10.340 10.4 10.34 2 11.017 11.0 11.01 3 11.492 11.6 11.51 6 12.672 12.7 12.66 7 13.207 13.2 13.22 9 14.225 14.2 Goranskij and Shugarov measured an additional star (V=11.71 B-V=0.44) at X=175 Y=560 that fills a gap in the bright end of the sequence. A star of about magnitude V=18 is located 6" SSW of V723 Cas. However light from this companion won't affect visual observations for several years. Bruce Sumner Revised 26 August 1999
