TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1883 SUBJECT: GRB030226: Optical decay index DATE: 03/02/26 12:55:11 GMT FROM: Derek Fox at CIT D.W. Fox (Caltech), P.A. Price (RSAA/ANU), and H.W. Chen (MIT) report: "Observations from the Dupont telescope at Las Campanas reveal continued fading of this afterglow (GCNs 1879, 1880, 1881, 1882). In four I-band images taken over the period from 0.1 to 0.2 days after the burst (Epoch: 26 Feb 03:46:32 UT), the afterglow decay may be fit with a power-law of index alpha~-0.85, as referenced against a large number of stars in the field."
