Special Notice #52: AM Her increasing in brightness

July 6, 2007

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.
