AE AQUARII
K. Horne and R. McCray, Space Telescope Science Institute,
communicate: "Simultaneous x-ray, ultraviolet, optical and radio
observations of the dwarf nova AE Aqr (R.A. = 20h37m34s.3, Decl. =
-1d02'57", equinox 1950.0; V = 10-12) are scheduled for June to study
the physical processes responsible for the 16 and 32 s pulsations and
violent flickering seen in this accreting binary. Ginga will observe
AE Aqr from June 2d02h through June 4d08h UT. IUE coverage will begin
on June 2d05h and end on June 3d21h. VLA will observe at the same
time as IUE (when the source is up). Time-resolved photometry or
spectroscopy in the optical or infrared would be extremely valuable
during this time. Potential observers wishing additional information
should contact us at HORNE@SCIVAX.SPAN or MCCRAY@SCIVAX.SPAN."
