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
Recent observations of the old nova intermediate polar magnetic catclysmic variable GK Per (Nova Per 1901) show the star brighter than minimum. However, it is too early to tell if an outburst is underway.
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.
February 6, 2006: The DQ Her-type (intermediate polar) magnetic variable DO Dra is in outburst. This star has outbursts at irregular intervals that last only 4-5 days. The
last outburst reported in the AAVSO International Database occurred in March
2005, when the star reached visual magnitude 11.2.
