[vsnet-alert 1286] New Algol variable, GSC 1062-33

[Ulrich Bastian <s01@ix.urz.uni-heidelberg.de>]

Dear colleagues and friends,

the new variable discovered by Klaus Bernhard of Linz (Austria)
was confirmed by Wolfgang Quester of Esslingen (Germany). He
observed a rise from main minimum on October 19, as predicted
in last week's alert. On October 22, however, 17:30 to 18:45 UT
he surprisingly observed a short part of a decline. This does
not fit the period of 12.922 which was used for the predictions
of last week.
 
As already argued, the period without any doubt is either
12.922 d or an integer fraction (1/2, 1/3, 1/4 ...)
of this. The short decline observed by Quester would fit as a
secondary minimum for a period of 12.922/5=2.584 days. This
period is not excluded by the original discovery observations
of Bernhard and, perhaps not quite incidentally, is the longest
possible period in which the secondary minimum would not be 
highly exccentric!

Thus, the American and Japanese friends are in a good position
to help determine the true period  -  contrary to the 
expectations of last week.

Best regards,
U. Bastian
