Masi (University of Rome "Tor Vergata" and European Southern Observatory, Chile), B. L. Jensen, J. Hjorth (Copenhagen University) and R. Michelsen (Astronomical Observatory, Copenhagen) report: Further to GCN 1960, we performed additional photometry of the OT initially reported by Gilmore at al. (GCN 1949). The Danish 1.54m telescope (La Silla) + DFOSC CCD camera were used to grab three, 360s R-band images; summing them we obtained the following Rc magnitudes (based on GCN 1948): Mar. 26, 00:54 UT 21.3 Rc Mar. 27, 00:50 UT 21.6 Rc Mar. 28, 03:45 UT 22.8 Rc (Errors around 0.2 mag) This message can be cited
