[vsnet-alert 313] AM Herculis

[Boris Gaensicke <boris@uni-sw.gwdg.de>]

Dear VSNet Observers, 

in a few days starts the probably largest observation campagin on the
polar AM Herculis since its discovery as an magnetic accretor 20 years
ago: ROSAT and IUE will monitor the source regularely, ISO and HST
observations are planned for the second half of the year and
groundbased optical spectroscopy and photometry will complement the
program.

From the two last observations in vsnet-obs it seems that AM Her is
slowly delining into a low state. It will be of great help to keep
track of the visual magnitude to estimate the needed IUE exposure
times. Therefore, I ask you to dedicate some attention to AM Her in
the next months.

Thank you very much in advance, 


 Boris Gaensicke
