Request for observations to support Spitzer observations
Active Dates: Aug. 17, 2005 – Aug. 31, 2005
Abstract:
Our assistance has been requested by Dr. Stefanie Wachter, Spitzer Science Center, Caltech, in observing the low-mass x-ray binary V818 Sco (Sco X-1) in support of her upcoming Spitzer observations of this object.
Justification:
Dr. Wachter has requested coverage for August 21, 22, and 23, and especially August 22, when her satellite observation is scheduled for 16:00 UT. Since this time falls during daylight hours in North and South America, observers in other parts of the world are urgently asked to try to observe V818 Sco at and around that particular time. Dr. Wachter has indicated that every observation will be helpful.
