BRIGHT VARIABLE STAR IN CASSIOPEIA
S. Nakano, Sumoto, Japan, reports the discovery by Akihiko Tago
(Ayabe, Tsuyama, Okayama-ken, Japan) of a brightening star on 30-s CCD
frames taken with a 70-mm f/3.2 lens and a Canon EOS 20Da digital camera
(limiting magnitude 12), with the following magnitudes available: Oct.
25.538 UT, 10.7; 27.409, 10.5; 30.411, 8.8; 31.469, 7.5. Tago adds that
a star of mag 11.8 (which did not vary on past images) is located very
close to the new variable's position, for which he identifies GSC
3656.1328 with R.A.= 0h09m21s.81, Decl.= +54o39'43".8, equinox 2000.0);
apparently this is the same star listed in the USNO-A2 catalogue as
1425.00229853, having position end figures 22s.00, 44".0, with blue mag
11.9 and red mag 11.3.
