Alert Notice 532: Observations requested for KIC 8462852

October 20, 2015: The AAVSO requests time-series observations of the enigmatic variable object KIC 8462852 beginning immediately and continuing through at least the end of the current observing season. The star is relatively bright (V=11.88) and shows aperiodic dips of a few tenths of a magnitude, the causes of which are unknown. The object is not known to be a close binary or a young stellar object, and there are no other typical indicators of circumstellar material such as infrared emission.

Annual Meeting early registration ends Friday October 23!

Special Notice #408: Developing planetary systems dust production study - second segment of observations

October 2, 2015:  Further to AAVSO Alert Notice 511, issued in March 2015, Dr. George Rieke (University of Arizona) and colleagues' campaign to monitor planetary debris disks for variability using the Spitzer Space Telescope continues. AAVSO observations are requested to rule out variability of the stars themselves.

The second segment of observations of the four targets takes place from now into January 2016 according to the schedule below.
