TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2104 SUBJECT: GRB030329: More AAVSO VR obs DATE: 03/04/06 19:40:40 GMT FROM: AAVSO GRB Network at AAVSO A. Price, B. Monard, A. Oksanen, T. DiLapo, D. West, D. Kaiser, D. Starkey, P. Nelson, P. Pääkkönen and J. Mattei (AAVSO); T. Durig, A. L. Seifert, C. B. Norton, G.F. Garland, J.K.Cole, J.B. Cherry (University of the South); A. Henden (USRA/USNO) report on behalf of the AAVSO International GRB Network: This is a 3rd set of observations of the OT found by Peterson and Price (GCN 1985) dating from March 29th to April 6th. Included in the observations is a URL where a full report (equipment, seeing, etc.) is available. Many times the original FITS image is also available. When time series data is available we only put the first and last observation. A light curve of all AAVSO data to date has been made by B. Gary and posted at http://www.aavso.org/grb/grb030329.jpg Bruce L. Gary, .25m at Arizona, USA.
