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.

Alert Notice 511: Monitoring requested for developing planetary systems dust production study

Campaign continued through 2017 at least. Also, campaign updated in  AAVSO Special Notice #408 (20151002).

March 13, 2015: Dr. George Rieke (University of Arizona) and colleagues have requested AAVSO assistance in monitoring four stars with developing planetary systems. The targets are RZ Psc, HD 15407A, V488 Per, and HD 23514. This campaign is similar to the one conducted in 2013 (see AAVSO Alert Notice 482).
