TITLE: GCN CIRCULAR NUMBER: 15478 SUBJECT: GRB 131108A: CARMA 3mm detection DATE: 13/11/09 19:27:44 GMT FROM: Daniel Perley at Caltech D. A. Perley (Caltech) reports on behalf of a larger collaboration: We observed the position of Fermi GRB 131108A (Racusin et al., GCN 15464) with the Combined Array for Research in Millimeter Astronomy at a frequency of 93 GHz (3mm) starting at 13:26 UT on 2013-11-09, 16.7 hours after the burst. Observations continued until 14:55 UT (midpoint t=17.5 hours.) A source is detected at a position consistent with the location of X-ray (Stroh & Kennea, GCN 15468) and optical (Xu et al., GCN 15471) afterglows at a flux of approximately ~2 mJy. Follow-up observations are planned. We thank the CARMA staff for their support in executing these observations.
