AM Her has been in an extended faint state (V=15.4) for the past two years. Just over the last few days, we have seen observations that show AM Her increasing in brightness by about a magnitude. While flaring of this order has occurred before, we ask that observers raise the priority of AM Her observations to keep an eye on this latest activity. There is the potential for triggering satellite observations if AM Her is going into outburst.
SUBMIT OBSERVATIONS TO THE AAVSO
April 2, 2015: Dr. Axel Schwope (Leibniz Institute for Astrophysics Potsdam, Germany) has requested AAVSO observers' assistance in monitoring the magnetic variable AM Her in support of upcoming XMM-Newton plus NuSTAR (Nuclear Spectroscopic Telescope Array) observations.
The XMM-Newton observations are scheduled for 2015 April 06 02:37:02-15:07:02 UT. The NuSTAR observations have not been made final yet but are expected to run longer. A Special Notice will be issued when the NuSTAR schedule is known.
