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  <aavso@aavso.org>

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

 * Durig et al., Gary, Starkey, Oksanen, West, Nelson, Pääkkönen and
Kaiser used Henden et al. photometry (GCN 2023) for comparison. DiLapo
used USNOA2. Monard used Tycho-2.

 * Pääkkönen's R filter (Rg) is a custom designed filter. Info at:

 The AAVSO International GRB network is greatful for a generous grant from
the Curry Foundation and to NASA for the financial support for the High
Energy Workshops for Amateur Astronomers.
