TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2058 SUBJECT: AAVSO V & R observations of GRB030329 DATE: 03/04/01 02:44:00 GMT FROM: AAVSO GRB Network at AAVSO A. Price (AAVSO) reports on behalf of the AAVSO International GRB Network: The AAVSO International GRB Network has obtained B, V, R, and unfiltered photometry of the afterglow to GRB030329 from numerous sources across the globe over the past 3 days. See notes for details and access to time series data. Berto Monard, South Africa Unfiltered = 14.06 @ 2003.03.29 17:15 to Unfiltered = 15.01 @ 2003.03.29 23:37 exposures: 317X45-60s Arto Oksanen, 0.4m at Nyrola Observatory, Finland R = 14.50 @ 2003.03.29 20:22:23 to R = 14.75 @ 2003.03.29 22:28:03 exposures: 10X120s (out of 148 total) Tim Schrabback and Anja von der Linden, 1.06m at Observatory Hoher List of Bonn University, Germany R = 15.0 @ 2003.03.29 22:55 exposure: 1800s Peter Brown, 0.41m at Orson Pratt Observatory, Brigham Young University, Utah USA R = 15.2 @ 2003.03.30 02:38 to R = 16.2 @ 2003.03.30 10:41 exposures: 1X300s Dan Kaiser, 0.35m at Crescent Moon Observatory, Indiana USA V = 16.62 2003.03.31 01:32:04 to V = 16.97 2003.03.31 06:18:06 R = 16.26 2003.03.31 02:10:12 to R = 16.53 2003.03.31 06:22:37 Bill Aquino, 0.3m with Buffalo Astronomical Association in New York, USA V = 16.71 @ 2003.03.31 05:33:03 exposures: 4X180s exposure Notes: * Detailed reports (observing equipment, location, conditions, etc.) and many original FITS files available at ftp://ftp.aavso.org/grb/GRB030329 or by e-mailing aavso@aavso.org. * Brown, Kaiser, Monard, and Oksanen have time series data spanning the observations posted here. Full data has already been or will be posted soon to the URL above. * Aquino, Kaiser, and Oksanen used comparison star photometry from Henden et al. (GCN 2023). Brown used comp star A described on the finder chart by Rumyantsev et al. (GCN 2005). Schrabback et al. used comp star A described on a different finder chart by Martini et al.(GCN 2012). Monard's comp star is from USNOA2, 14.0R, 3' NNE of GRB. * The decay rate in Monard's exposure varies from 0.191 CR/h in the beginning of the run to 0.103 CR/h at the end. Kaiser's time series data is fairly constant until about 5:40 when the OT begins to fade again. The CCD used by Oksanen plus other components of the AAVSO International GRB network were funded by a generous grant from the Curry Foundation.
