Close monitoring of the activity of the star throughout the next 3 weeks would be very helpful for the interpretation of the HST data. An AAVSO chart of AM Her can be retrieved via http://charts.aavso.org/ Clear skies! Boris Gaensicke, University of Southampton Knox Long, Space Telescope Science Institute
