Description
We have been monitoring the optical counterpart of the TeV emitting binary LSI +61 303 (V615 Cas) since November 2005 with the Faulkes Telescope North (on Haleakala, Maui), as part of a program to monitor long-term variability in X-ray binaries. Prompted by the recent SGR-like burst observed from a source in the region of LSI +61 303 (GCN 8209; ATel #1715; see also ATel #1731, #1740), we searched for unusual optical activity during the last two months (3rd August - 1st October).
