Dear Observers:

Photometric and spectroscopic observations of the dwarf nova SS Cyg and
the flare star AD Leo are requested during an upcoming observation with
the ASCA (formerly Astro-D) satellite.

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.
