Alert Notice 356: Request to monitor PQ Andromedae for HST Observations

August 24, 2007: Dr. Paula Szkody (University of Washington) has requested our help in monitoring the nova PQ Andromedae for upcoming Hubble Space Telescope observations. The HST observations are scheduled to be made during the week of 2007 September 10-16 UT. Dr. Szkody requests monitoring of this object during the two weeks prior to the observing window, and intensive monitoring during the 24-48 hour period during which observations will be made.

PQ Andromedae (0223+39) is at R.A. 02:29:29.61 , Dec +40:02:40.0
