Abstract
THE VARIABLE STARS U CEPHEI AND U GEMINORUM.—We learn from Mr. Knott that Ceraski's short-period variable in Cepheus was at a minimum on March 29 at about 12h. 45m. G.M.T.; clouds prevented observations till nh. 35m., when it had barely fallen to minimum; for two hours, 11h. 45m.—13h. 45m., the star's light was sensibly constant—about 9.4m. On April 3 Mr. Knott again obtained a pretty complete observation; the time of minimum, taking the middle of the phase, was 12h. 24m. G.M.T.; for nearly 2h. 30m., or from 11h. 10m, to 13h. 36m., the star remained about 9.4m. Guided by these and previous observations the following approximate times of minima are inferred, and it is to be hoped that the series may be well observed:—
