• GCN Circular #4423
  E. Retter (PSU), S. Barthelmy (GSFC), D. Burrows (PSU), M. Chester (PSU), N. Gehrels (GSFC), S. Immler (GSFC), F. Marshall (GSFC), T. Sakamoto (GSFC) on behalf of the Swift team:
  At 02:45:43 UT, Swift-BAT triggered and located GRB 060102 (trigger=175603). The spacecraft did not slew to this burst because of the Moon observing constraint. The BAT on-board calculated location is RA,Dec 328.852d,-1.846d {21h 55m 25s,-01d 50' 44"} (J2000), with an uncertainty of 3 arcmin (radius, 90% containment, stat+sys). The BAT light curve shows a multi-peak structure with a total duration of ~20 sec. The peak count rate was ~1500 counts/sec (15-350 keV), at ~1 seconds after the trigger.
• GCN Circular #4424
  S. Barthelmy (GSFC), D. Burrows (PSU), M. Chester (PSU), N. Gehrels (GSFC), S. Immler (GSFC), E. Retter (PSU), T. Sakamoto (GSFC) on behalf of the Swift team:
  We correct the trigger time for GRB 060102 (trigger=175603) in GCN Circular #4423. A data corruption problem caused the conversion from spacecraft time to Universal Time to be off by 16 million seconds. The correct trigger time for GRB 060102 is 21:17:28 UT (+/- ~2 sec for the unknown correction factor).
• GCN Circular #4427
  E. Armstrong (UCSD), J. P. Halpern, S. Tyagi, & N. Zimmerman (Columbia U.) report on behalf of the MDM Observatory GRB follow-up team:
  "We observed the position of GRB 060102 in the R band using the MDM 1.3m. The sum of three 5-minute exposures beginning on Jan. 3 02:28 UT, or 5.2 hours after the burst, shows no new object within the revised BAT error circle (Krimm et al., GCN 4425) to a 5-sigma limit of R > 20.5 (statistical + systematic) in comparison with the Digitized Sky Survey."
• GCN Circular #4434
  A. Retter, J. Kennea, D. Burrows, D. Grupe, J. Nousek (PSU); N. Gehrels (GSFC)
  GRB 060102 (trigger #175603; Retter et al. GCN 4423) was observed with the XRT for 2 ksec about 47 hours after the BAT trigger. No afterglow candidate was found. The 3-sigma upper limit is 0.003 counts/s (1.5e-13 ergs/s/cm^2). Earlier observations were prohibited by sun and moon constraints. No further observations are planned.
