GCN Circular #4616
D. Gotz (CEA, Saclay) and S. Mereghetti (IASF, Milano) on behalf of the IBAS Localization Team report:
GRB 060130 shows a single pulse light curve. Its peak flux integrated over 1 s (20-200 keV band) is 0.22 ph (2x10e-8 erg)/cmsq/s. Its fluence in the same energy band is 3x10e-7 erg/cmsq.

Report:
The wide field camera of the FRAM telescope, located at Pierre Auger observatory in Malargue, Argentina, observed the field of INTEGRAL GRB 060130 (D. Gotz et al., GCN 4615, 4616) starting at 9:09:36 UT, eg. 4h 13m after GRB. Observations was manually triggered and started under dawn sky (but at favorable zenith distance ~ 25 deg).
Comparison with GSC does not reveal any new source within INTEGRAL error box down to R mag ~ 13.

GCN Circular #4618
B. E. Cobb (Yale), part of the larger SMARTS consortium, reports:
Using the ANDICAM instrument on the 1.3m telescope at CTIO, we obtained optical imaging of the error region of GRB 060130 (GCN 4615, Mereghetti et al.) starting 09:14 2006-01-30 UT (~4.3 hours post-burst). The imaging was conducted during twilight, which limited the number and depth of the images we were able to obtain. The ANDICAM's optical field of view is 6'x6' and, therefore, covers the entire GRB error circle.
Preliminary visual comparison of a 30 second R-band image to the SDSS does not reveal any new sources. The detection limits of this ANDICAM image are slightly shallower than that of the SDSS.
GCN Circular #4619
V. Testa, L.A. Antonelli, A. Melandri, S. Covino, E. Molinari, G. Chincarini, F.M. Zerbi, G. Tosti, F. Vitali, P. Conconi, G. Cutispoto, G. Malaspina, L. Nicastro, E. Palazzi, E. Meurs, P. Goldoni, on behalf of the REM/ROSS team, report:
The field of GRB 060130 (Mereghetti et al. GCN 4615) was observed with the REM telescope located in La Silla (Chile).
The field was imaged with the REMIR near infrared camera in the J, H, K' filters, starting at UT 9:29, approximately 4.4 hrs from the burst, for a total integration time of 600 s in each filter.
No sources are detected within the IBAS error circle down to the limiting magnitudes of 2MASS catalog.
Further observations are in progress.

GCN Circular #4620
Jesper Nielsen (DARK/Sindal School), Brian L. Jensen, Johan P. U. Fynbo, Jens Hjorth (DARK Cosmology Centre), Christoffer Karoff (IFA/U. of Aarhus) report on behalf or a larger collaboration:
"Using DFOSC on the Danish 1.5m telescope at La Silla, we have obtained R-band imaging of the field of the Integral-detected GRB060130 (Mereghetti et al., GCN #4615) starting at Jan 30.375 (4.5h after the trigger). Visual comparison with the DSS-2 does not reveal any transient sources brighter than the DSS-2 limit. Our image reaches a detection limit slightly deeper than R=22.

GCN Circular #4624
J. A. Kennea (PSU), O. Godet (U. Leicester), D. N. Burrows (PSU) and N. Gehrels (NASA/GSFC) report on behalf of the Swift Team:
Swift began a target of opportunity observation of the INTEGRAL detected burst GRB 060130 (GCN 4615) at 15:18:04 UT January 30th 2006, 10.3 hours after the burst. We have analyzed 10ks of Swift/XRT data of the field of the INTEGRAL burst and detect no source in or near the 2 arcmin INTEGRAL error circle. Assuming a Crab like spectrum and galactic absorption, we calculate a 3 sigma upper limit on the flux of the afterglow of 5 x 10^-14 erg/s/cm^2 (0.2-10 keV).
GCN Circular #4625
Jesper Nielsen (DARK/Sindal School), Christina Thoene, Chloe Feron, Johan P. U. Fynbo, Brian L. Jensen, Jens Hjorth (DARK Cosmology Centre), Christoffer Karoff (IFA/U. of Aarhus) report on behalf or a larger collaboration:
"Using DFOSC on the Danish 1.5m telescope at La Silla, we have obtained further (3x600sec) R-band imaging of the field of the Integral-detected GRB060130 (Mereghetti et al., GCN #4615) around Jan 31.3. By comparing to our image taken 4.3 hr after the burst (GCN #4620) we place a 3-sigma upper limit of R=23 on any transient sources 4.3 hr after the burst."
GCN Circular #4626
J. Haislip, C. MacLeod, M. Nysewander, A. LaCluyze, D. Reichart, J. A. Crain, A. Foster, K. Ivarson, J. Kirschbrown report on behalf of the UNC team of the FUN GRB collaboration:
We observed the localization of GRB 060130 (Mereghetti et al., GCN 4615) with three of the PROMPT telescopes simultaneously in r'Iz' beginning 23.8 hours after the burst under the automated control of Skynet:
```
Filter  Telescope  Start (UT)  Stop (UT)  Exposures  Total (hr)
r'      PROMPT-4   04:45:52    06:34:20   71 x 80s   1.80
I       PROMPT-1   04:46:02    06:33:52   71 x 80s   1.78
z'      PROMPT-5   04:45:42    06:34:53   72 x 80s   1.82
```
No new source is found to I > 19.8 mag (3 sigma). The magnitudes have been calibrated to five USNO-B1.0 stars.
PROMPT is currently being built and commissioned at CTIO.
