We co-added 25 unfiltered 30s duration frames, taken between 20s and 17min after GRB 030501 (Mereghetti et al., GCN 2183). We do not detect any new source up to the limiting magnitude of R=18.0....Full Text

We have imaged the error box of GRB 030501 (Mereghetti et al. 2003, GCN 2183) with AT-64 telescope of CrAO. Several unfiltered images were taken on May 1, 21:59-23:12 (18.8 hours after GRB) and May 3, 22:36-23:34 (2.8 days after GRB). Visual comparison with DSS-2I and comparison of the combined images in different epochs (May 1 and May 3) reveals no new or fading objects within GRB error...Full Text

We have observed the full error box of GRB 030501 (Mereghetti et al. 2003, GCN 2183) using the Wise observatory 1m telescope + SITe CCD camera, starting 2003 May 2 00:05 UT (16.5 hours after the burst). Two 600s R-band frames were obtained....Full Text

Data reported in GCN 2194 were affected by error in time delay. ipn Correct Konus-Wind - Helicon annulus is: RA(2000) = 224.210 deg, Decl(2000) = -21.142 deg, Radius = 73.23 +/- 0.70 degrees (3 sigma )....Full Text

"The candidate GRB 030501 optical afterglow of Boer & Klotz (GCN 2188) is present in archival images of the Second Palomar Optical Sky Survey (XDSS) and the Two-Micron All-Sky Survey (2MASS). Although the object, which appears to be a star, is undetected in the XDSS B-band image, and faint in the XDSS R-band image, it is well-detected in the XDSS I-band image and extremely bright (among the...Full Text

We observed the localisation of GRB 030501 given by INTEGRAL (GCN 2183). The observations started at 3:10:37.6, less than 20 seconds after the burst trigger, while it was still active. ...Full Text

Ulysses and INTEGRAL (SPI-ACS) also observed this burst (GCN 2183). As observed by Ulysses, it had a duration of approximately 75 seconds, a 25-100 keV fluence of approximately 1.1E-06 erg/cm2, and a peak flux of approximately 4.9E-07 erg/cm2 s over 0.25 seconds. Because this event was quite weak, these parameters are uncertain by a factor of about 2....Full Text
