We have received a telex from D. M. Mouchet at Brussels University requesting our assistance during his observing run of cataclysmic variables at European Southern Observatory in Chile from January 30th through February 1st, 1982. He and his colleagues will be monitoring the outbursts of those stars listed below, both spectroscopically and photometrically.

They are depending on us - you - to inform them of the outbursts. Please observe as many of the stars listed here as possible, and call me (HQ - 617-354-0484 on weekdays; Home - 617-xxx-xxxx evenings until 11 pm and weekends) if any of them brighten.

SPECIAL THANKS:

My sincere thanks to all of you who participated in last week's IUE observing run of France Cordova's. Your observations, generally made at sub-zero temperatures, were a real sign of your dedication  and devotion to variable star observing and to astronomy. During the IUE run, of the stars on France's list, only CN Ori went up, and she was able to obtain good IUE data during its minimum, its rise, and at maximum.

Many, many thanks, again!

Good observing! I look forward to hearing from you.
