"We began imaging the position of Swift Burst #113225 at 2005-04-02
06:27:42.5 UTC with PAIRITEL on Mt Hopkins. There appears to be be no
object brighter than the 2MASS catalogue in J, H, and K. In comparing two
epochs, there appears to be a fading source at:
09:05:55.42, 16:37:25.5 (J2000)
Further analysis is in progress."

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."
