TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3170 SUBJECT: GRB 050402A: IR Analysis DATE: 05/04/02 10:01:42 GMT FROM: Josh Bloom at Harvard/CFA H. W. Chen (MIT), J. S. Bloom (UCB), J. X. Prochaska (UCSC) & C. Blake reports on behalf of a larger collaboration: "Upon more detailed analysis following GCN #3168 we cannot confirm our earlier claim of significant variability as suggested. We thus find no variable or new source to the 2MASS detection levels in J, H, and K starting ~18 min after the GRB." This message may be cited.
