Announcement of the Campaign (July 19, 2007)
The GLAST Large Area Telescope AGN science group is starting a multiwavelength campaign for blazar 3C454.3 (2251+158), effective immediately and continuing through the middle of August. This Ad-Hoc Intensive Campaign (AIC) is prompted by brightening in the radio, optical and X-ray. Swift Target of Opportunity observations are planned. A Spitzer observation is scheduled.
Campaign managers: Matthias Kadler, mkadler@milkyway.gsfc.nasa.gov , and Ann Wehrle, awehrle_ssi@earthlink.net
Please contact them if you have telescope time and are interested in joining this campaign. For this campaign, the policy on data sharing will be: if you observe and send data that can be used, you are a co-author of a resulting multiwavelength publication unless you just want an acknowledgment. Anyone who contributes data keeps the right to publish those data separately.
Although there will be no GLAST gamma-ray data (GLAST is still in testing in Arizona), the opportunity for good multiwavelength coverage of this source right now is excellent at other wavelengths. In addition to the intrinsic scientific interest, this campaign can be used to establish planning and coordination routines for the upcoming years of multiwavelength blazar observations with GLAST.
