We imaged the field of GRB 061218 detected by SWIFT (trigger 251863) with the TAROT robotic telescope (D=25cm) located at the European Southern Observatory, La Silla observatory, Chile....Full Text

GRB 061218: TORTOREM optical upper limits	Karpov et al.
	GCN 5941

Posted by Giuseppe Greco

06/12/19 16:05:22 GMT

The field of GRB 061218 (Zane et al. GCN 5936) has been observed by the TORTORA (Telescopio Ottimizzato per la Ricerca di Transienti Ottici RApidi) wide-field fast camera (12 cm diameter, 20x25 deg FOV) mounted on REM robotic 60-cm telescope located at La Silla (Chile). The burst was initially outside the camera field of view. The system was repointed and the TORTORA began to acquire frames...Full Text

GRB 061218, Swift-BAT refined analysis	Sato et al.
	GCN 5940

Posted by Jay R. Cummings

06/12/19 00:32:19 GMT

Using the data set from T-120 to T+183 sec from the recent telemetry downlink, we report further analysis of BAT GRB 061218 (trigger #251863) (Zane, et al., GCN 5936). The BAT ground-calculated position is RA, Dec = RA 149.238, DEC -35.221 deg which is ...Full Text

GRB 061218, SMARTS optical/IR observations	Cobb
	GCN 5938

Posted by Bethany Cobb

06/12/18 05:35:07 GMT

Using the ANDICAM instrument on the 1.3m telescope at CTIO, we obtained optical/IR imaging of the error region of GRB 061218 (GCN 5936, Zane et al.), with a mid-exposure time of 2006-12-18 04:44:48 UT, which is ~0.7 hours post-burst. Our optical images have a field of view of 6'x6' and, therefore, cover the entire GRB error circle. Our IR images have a smaller field of view, covering a...Full Text

GRB 061218: REM prompt observations	D'Avanzo et al.
	GCN 5937

Posted by Paolo D'Avanzo

06/12/18 05:17:33 GMT

We observed the field of the possible GRB 061218 (Zane et al. GCN 5936) with the robotic 60-cm REM telescope located at La Silla (Chile). A set of observations was performed automatically in the optical and near infrared filters (V, R, I and J, H, K, z) starting on 2006 December 18 at 04:07:14 UT, 71 s after the BAT trigger and 129 s after the GRB time....Full Text
