OBSERVATION REPORT A. Oksanen on behalf of Nyrola observatory GRB Team reports: The bright afterglow was observed with the 0.4 SCT telescope of Nyrölä observatory using short (60/120 s) exposures and Rc-filter. Sky was almost cloudy, but time to time the afterglow was visible and measurable. Photometry (AIP4Win) from the best frames (Henden photometry file reference) follows: see photometry_20030329.txt
TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2010 SUBJECT: GRB 030329: visual observations DATE: 03/03/30 00:33:03 GMT FROM: Arto Oksanen at Nyrola Obs., Finland
A. Oksanen (Nyrola Observatory), R. Henriksson and M. Tuukkanen (the Finnish Deep Sky section of Astronomical Association Ursa) report: We observed the optical afterglow of GRB030329 reported by Peterson and Price (GCN 1985) visually about 8 hours after the burst. M. Tuukkanen observed the OT In Pornainen, Finland with a 0.63 m Newton telescope for about one hour starting March 29, 2003 19:30 UT. He reported it as a faint starlike object seen easily with direct vision. He did not see any flickering or distinct color. R. Henriksson was observing in Orivesi, Finland with his 0.30 m Newton telescope using 200x magnification at 20:05 UT. He reported the object stellar and faint, visible only with averted vision. His scanned sketch with notes is available on web: http://archive.ermiksson.net/record.php?id=4112 Both observers estimated the visual magnitude as 14.3 by using the 14.2 magnitude GSC 1434:322 star North of OT as reference.

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.

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.
OBSERVATION REPORT A. Oksanen on behalf of Nyrola observatory GRB Team reports: Photometry run in V and Rc was performed with the 0.40 m SCT telescope under good conditions from March 31 19:00 UT to April 1, 2003 01:30 UT. The light curves are pretty flat as expected, but there is one intresting feature near noise level. The OT started to fade faster around 23 UT and then started to rise again. This 0.1 magnitude dip is visible both in Rc and V. BUT the dip seem to be 30 minutes later in R! Attendum April 4, 2003: This dip was not confirmed statistically from the data. More datailed analysis is in progress.

The afterglow was imaged with Rc filter on April 9/10, 2003 20:37-00:12 UT (11 days after the burst!). Total of 50 240s exposures were stacked using Sigma Reject average. The afterglow magnitude was measured with MaxIm/DL to R=19.17 +/- 0.07 on the mid epoch of April 9.93 UT using all eight reference stars from the AAVSO f-scale chart based on Henden photometry file.
