Maselli (INAF-IASFPA), A. Melandri (INAF-OAB), D. M. Palmer (LANL), T. Sakamoto (AGU), M. H. Siegel (PSU) and T. N. Ukwatta (MSU) report on behalf of the Swift Team:
At 03:12:13 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130610A (trigger=557845). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 224.416, +28.191 which is
```
   RA(J2000) = 14h 57m 40s
   Dec(J2000) = +28d 11' 28"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a multi-peaked structure with a total duration of about 30 sec. The peak count rate was ~2700 counts/sec (15-350 keV), at ~5 sec after the trigger.
The XRT began observing the field at 03:14:26.3 UT, 133.0 seconds after the BAT trigger. XRT found a bright, uncatalogued X-ray source located at RA, Dec 224.4218, 28.2048 which is equivalent to:
```
   RA(J2000)  = +14h 57m 41.23s
   Dec(J2000) = +28d 12' 17.3"
```
with an uncertainty of 6.6 arcseconds (radius, 90% containment). This location is 52 arcseconds from the BAT onboard position, within the BAT error circle. No event data are yet available to determine the column density using X-ray spectroscopy.
UVOT took a finding chart exposure of 150 seconds with the White filter starting 140 seconds after the BAT trigger. There is a candidate afterglow in the rapidly available 2.7'x2.7' sub-image at
```
  RA(J2000)  =	14:57:40.89 = 224.42037
  DEC(J2000) = +28:12:25.7  =  28.20715
```
with a 90%-confidence error radius of about 0.62 arc sec. This position is 9.6 arc sec. from the center of the XRT error circle. The estimated magnitude is 17.91 with a 1-sigma error of about 0.14. No correction has been made for the expected extinction corresponding to E(B-V) of 0.02.

Skynet observed the Swift/XRT localization of GRB 130610A (Cummings et al., GCN 14842, Swift trigger #557845), starting at 2013-06-10, 03:14:05 UT (t=2.03m post-trigger), with three 16" telescopes of the PROMPT array at CTIO, Chile. We detect a fading afterglow in B, V and I bands at: RA = 14:57:40.9, Dec = 28:12:25.5 (J2000.0), consistent with the UVOT source position reported in GCN 14842.
The afterglow rises until t~3.4m, at which time the apparent magnitudes are B~18.1, V~17.1, I~16.6. A preliminary light curve is at: http://www.skynet.unc.edu/grb/grb130610a.png

We observed the field of GRB 130610A (Cummings et al., GCN 14842) with the 1.3m PAIRITEL located at Mt. Hopkins, Arizona. Observations began at 2013-Jun-07 03h35m37s UT, 0.39 hr after the Swift Trigger. In mosaics (effective exposure time of ~5.85 minutes) taken simultaneously in the J, H, and Ks filters, we detect the optical afterglow (Cummings et al., GCN 14842; Melandri et al., GCN 14843; Trotter et al. GCN 14844). The preliminary K-band reduction is corrupted.

S. B. Cenko (NASA/GSFC) and D. A. Perley (Caltech) report on behalf of a larger collaboration:
We have imaged the optical afterglow of the Swift GRB 130610A (Cummings et al., GCN 14842) with the robotic Palomar 60 inch telescope. A series of 90 s exposures in the g', r', i', and z' filters were begun starting at 04:23 UT on 2013 Jun 10 (1.18 hr after the Swift trigger). We detect the afterglow in individual exposures in all 4 filters. Using nearby point sources from SDSS for calibration, we measure a magnitude of r' = 19.8 in our initial images. Compared with earlier observations with the Liverpool telescope (Melandri et al., GCN 14843), this suggests a power-law decay index of ~ 1.2.

Using the data set from T-60 to T+243 sec from the recent telemetry downlink, we report further analysis of BAT GRB 130610A (trigger #557845) (Cummings, et al., GCN Circ. 14842). The BAT ground-calculated position is RA, Dec = 224.414, 28.187 deg which is
```
    RA(J2000)  =  14h 57m 39.3s
    Dec(J2000) = +28d 11' 13.8"
```
with an uncertainty of 2.4 arcmin, (radius, sys+stat, 90% containment). The partial coding was 96%.
The mask-weighted light curve shows a single FRED peak. T90 (15-350 keV) is 46.4 +- 11.2 sec (estimated error including systematics).
The time-averaged spectrum from T-7.04 to T+61.02 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.27 +- 0.08. The fluence in the 15-150 keV band is 2.5 +- 0.1 x 10^-06 erg/cm2. The 1-sec peak photon flux measured from T+4.53 sec in the 15-150 keV band is 1.7 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

J.P. Osborne, A.P. Beardmore, P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team.
Using 7625 s of XRT Photon Counting mode data and 8 UVOT images for GRB 130610A, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 224.42032, +28.20711 which is equivalent to:
```
RA (J2000): 14h 57m 40.88s
Dec (J2000): +28d 12' 25.6"
```
with an uncertainty of 1.4 arcsec (radius, 90% confidence).
This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177).

B. Sbarufatti (INAF-OAB/PSU), G. Stratta (ASDC), P. D'Avanzo (INAF-OAB), J.A. Kennea (PSU), M.C. Stroh (PSU), D.N. Burrows (PSU), A.P. Beardmore (U. Leicester), P.A. Evans (U. Leicester), B.P. Gompertz (U. Leicester) and J.R. Cummings report on behalf of the Swift-XRT team:
We have analysed 11 ks of XRT data for GRB 130610A (Cummings et al. GCN Circ. 14842), from 139 s to 25.1 ks after the BAT trigger. The data comprise 116 s in Windowed Timing (WT) mode with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Osborne et al. (GCN. Circ 14851).
The light curve can be modelled with a power-law decay with a decay index of alpha=1.17 (+/-0.03).
A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.04 (+/-0.15). The best-fitting absorption column is 2.6 (+2.8, -2.6) x 10^21 cm^-2, at a redshift of 2.092, in addition to the Galactic value of 1.9 x 10^20 cm^-2 (Kalberla et al. 2005). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.4 x 10^-11 (3.9 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Galactic foreground: 1.9 x 10^20 cm^-2
Intrinsic column:    2.6 (+2.8, -2.6) x 10^21 cm^-2 at z=2.092
Photon index:	     2.04 (+/-0.15)
```
If the light curve continues to decay with a power-law decay index of 1.17, the count rate at T+24 hours will be 3.2 x 10^-3 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 1.1 x 10^-13 (1.3 x 10^-13) erg cm^-2 s^-1.

We observed the field of GRB 130610A (Cummings et al. GCN 14842), using a 1-m telescope at Mt. Lemmon Optical Observatory (LOAO) in Arizona, US. The observation started at 2013-06-10 05:54:16 UT, about 2.7 hrs after the burst alert, and a series of images were taken in B, R, and I-band for about 40 min.
We identify the afterglow (Melandri et al. GCN 14843), in all the three bands, with approximate magnitude of B = 21.35 +- 0.12, V=20.90 +- 0.26, and R=20.35 +- 0.18, all in Vega magnitude, calibrated against a star in the vicinity using SDSS photometry converted to BVR.
We thank the LOAO operator, In-Kyung Baek for performing the observation.

G. Fitzpatrick (UCD) and V. Pelassa (UAH) report on behalf of the Fermi GBM Team:
At 03:12:10.50 UT on 10 June 2013, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 130610A (trigger 392526733 /130610133) which was also detected by the Swift/BAT (Cummings et al., GCN Circ. 14842). The GBM on-ground location is consistent with the Swift position.
The GBM light curve consists of a single peak with a duration (T90) of about 28 s (50-300 keV). The time-averaged spectrum from T0-2.6 s to T0+25.7 s is adequately fit by a power law function with an exponential high-energy cutoff. The power law index is -1.0 +/- 0.1 and the cutoff energy, parameterized as Epeak, is 294.9 +/- 42.9 keV
The event fluence (10-1000 keV) in this time interval is (6.1 +/- 0.4)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+8.0 s in the 10-1000 keV band is 4.5 +/- 0.9 ph/s/cm^2.
The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog.

M. H. Siegel (PSU) and J. R. Cummings (NASA/UMBC) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 130610A 140 s after the BAT trigger (Cummings et al., GCN Circ. 14842). A fading source consistent with the XRT position (Cummings et al. GCN Circ. 14842) is detected in the initial UVOT exposures.
The preliminary UVOT position is:
```
   RA  (J2000) =  14:57:40.88 = 224.42034 (deg.)
   Dec (J2000) = +28:12:25.8  =  28.20717 (deg.)
```
with an estimated uncertainty of 0.51 arc sec. (radius, 90% confidence).
Preliminary detections and 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the early exposures are listed below. The lack of detection in the NUV filters would be consistent with the z=2.1 redshift reported by Smette et al. (GCN Circ. 14848).

Klotz A. (IRAP-CNRS-OMP), Gendre B. (IRAP-CNRS-OMP), Boer M., Siellez K., Dereli H., Bardho O. (UNS-CNRS-OCA), Atteia J.L. (IRAP-CNRS-OMP) report:
We imaged the field of GRB 130610A detected by SWIFT (trigger 557845) with the TAROT robotic telescope (D=25cm) located at the European Southern Observatory, La Silla observatory, Chile.
The observations started 91s after the GRB trigger (17s after the notice). The elevation of the field decreased from 31 degrees above horizon and weather conditions were good.
The first image is trailed with a duration of 60.0s (see the description in Klotz et al., 2006, A&A 451, L39). We recorded the rise of the afterglow discovered by Melandri et al. (GCNC 14843).
We used the star NOMAD1 1182-0257977 R.A.=224.3892908 DEC=+28.2065917 R=14.11 to extract the light curve of the rise of the afterglow:

Magnitudes are not corrected for galactic dust extinction.
After the trailed image a technical problem prevented to obtain next images.
