behalf of the REM team:
The robotic 60-cm REM telescope located at La Silla (Chile) observed
automatically the field of the GRB 080330 (Mao et al., GCN 7537) on
March 30 03:42:11 UT (about 55 seconds after the burst).
We clearly detect the afterglow reported in GCNs 7536 (Klotz et al.),
7537 (Mao et al.) 7538 (Schaefer & Guver), 7539 (Gomboc et al.), 7542
(Bloom & Starr), 7544 (Malesani et al.), 7545 (Clemens et al.), 7546
(Lee et al.), 7550 (Wang et al.).
The R-band light curve between 70s < t-t0 < 1800s clearly shows an
initial rising with a maximum around 330s < t-t0 < 450s and a subsequent
plateau with a possible rebrightening at 900s < t-t0 < 1100s, as noted
in GCNs 7538 (Schaefer & Guver), 7543 (Klotz et al.) and 7552 (Kuin & Mao).
Further analysis is in progress.
