February 6, 2013: According to photometry provided by Don Collins (CDK, Swannanoa, NC), the eclipse in the b Per system (HD 26961), predicted for around 2013 January 25, is underway now and began February 4-5. Photometry - multicolor if possible - is urgently needed now to cover the rest of this eclipse, which may last for up to four days altogether, and see post-eclipse behavior of the system.
