GZ Cnc: still very active, urgent observation requested Dear Colleagues, We have received the attached reports from Arto Oksanen. Could someone start observing just now? The star looks very rich in flare-like events! Regards, Taichi Kato VSNET Collaboration team === GZ Cnc has just (02:15-02:30 UT) brightened 0.5 magnitudes! I planned to stop by now, but I will fillow the star a bit longer to see what it is up to. :) === the rapid brightening turned as rapid fading. It looks now like a very large amplitude (0.5 mag) and short duration (30 minutes) flare or something. There seem to be no clear pattern in my 6+ hour light curve. === Fading turned into another rapid rise. The star is hitting treeline any moment now. Hopefully someone is continuing from now on!
