[Aavso-photometry] Re:HD80606 Transit Opportunity

[RBissinger at aol.com]

All,

Based on some baseline photometry and observers' comments, we should try to use HD 80607 for the comparison star if you can resolve it from its HD 80606 visual companion, and if your photometry software can keep the the two stars separated.

Most folks will probably also have GSC 3431:892 in their field so it can serve as a backup comparison star should the observer not be able to use 80607, or it can serve as the check star.  I don't think there are many other usable stars in the field around 80606.

As we get more baseline photometry we can also get a better sense of the variability of these stars.

Best Regards,

Ron
