ASCA, the recently launched Japanese X-ray satellite, will soon be observing SS Cyg (V= ~8.2 to 12) for a 24 hour period during the week of May 31st. The M dwarf flare star AD Leo (V = 9.4, R = 7.7) will be observed for a 24 hour period during the week of May 24th. A more precise starting time for each observation is expected within the next 1 to 2 weeks. John Nousek, from Penn State, is the lead investigator for the observations of these objects during the performance verification phase of ASCA. Observers capable of participating in the observations of either object are encouraged to contact us at the address below. -Craig Robinson (robinson@astro.psu.edu) (814-863-4690)
