S.Mereghetti, A.Paizis (IASF- Milano), D.Gotz (CEA-Saclay), E. Bozzo, A.
Taylor, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf
of the IBAS Localization Team report:
a gamma ray burst lasting about 20 s has been detected by IBAS in the
IBIS/ISGRI data at 14:36:06 U.T. on July 13th.
Its refined coordinates (J2000) are:
RA: 255.209 [degrees]
DEC: 28.390 [degrees]
with an uncertainty of 2.5 arcmin (90% c.l.).
A preliminary analysis gives a peak flux in the 20-200 keV range of about
0.4 ph/cmsq/s (1 s integration time) and a fluence over the same energy
range of about 2 10e-7 erg/cmsq.
A plot of the light curve will be posted at

V. D'Elia (ASDC), N. Gehrels (NASA/GSFC), J. M. Gelbord (PSU),
E. A. Hoversten (PSU), K. L. Page (U Leicester) and M. H. Siegel (PSU)
report on behalf of the Swift Team:
Swift began a target of opportunity observation of GRB100713A on July
13, 2010 at 16:30 UT, approximately 1.9 hours after the burst was
detected by INTEGRAL. Swift data for these observations utilize Target
ID 20143.
The XRT began observing the field at 16:20:34.3 UT, 6.2 ks after the
INTEGRAL trigger. Using promptly downlinked data we find an
uncatalogued X-ray source located at RA, Dec 255.20192, 28.39489 which
is equivalent to:
RA(J2000) = 17h 00m 48.46s
Dec(J2000) = +28d 23' 41.6"
with an uncertainty of 4.9 arcseconds (radius, 90% containment). This
location is 29 arcseconds from the INTEGRAL position, within the
INTEGRAL error circle. This position may be improved as more data are
received; the latest position is available at
http://www.swift.ac.uk/sper. We cannot determine whether the source is
fading at the present time.
A power-law fit to a spectrum formed from promptly downlinked event
data gives a column density in excess of the Galactic value (5.01e+20
cm^-2, Kalberla et al. 2005), with an excess column of 7.2
(+8.61/-6.14) x 10^21 cm^-2 (90% confidence).
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 6246 seconds after the INTEGRAL trigger. No credible afterglow
candidate has been found in the initial data products. The 2.7'x2.7' sub-image
covers 100% of the XRT error circle. The typical 3-sigma upper limit has
been about 19.6 mag. The 8'x8' region for the list of sources generated
on-board covers 100% of the XRT error circle. The list of sources is
typically complete to about 18 mag. No correction has been made for the
expected extinction corresponding to E(B-V) of 0.06.
Burst Advocate for this burst is V. D'Elia (delia AT asdc.asi.it).
Please contact the BA by email if you require additional information
regarding Swift followup of this burst. In extremely urgent cases, after
trying the Burst Advocate, you can contact the Swift PI by phone (see
Swift TOO web site for information: http://www.swift.psu.edu/too.html.)

(INAF-OAB Brera), report:
"Following the detection of GRB 100713A by INTEGRAL (Mereghetti et al.
GCNC 10951), we have obtained optical images with the 0.6m TELMA robotic
telescope at the BOOTES-2 station and with 1.5m telescope at the
Observatorio de Sierra Nevada (OSN), both located in Southern Spain.
At the position of the X-ray afterglow detected by SWIFT/XRT (D'Elia et
al. GCNC 10952) we do not detect any optical source down to I = 23 in
the co-added 1.5m OSN image (3600-s exposure at 21:07 UT, i.e. 6.5-hr
after the onset of the burst).
Due to the low Galactic extinction (Av = 0.2), this INTEGRAL GRB is very
suitable for follow up. Deeper observations (specially at near-IR
wavelengths) are encouraged".

We observed the field of GRB100713A (Mereghetti et al. GCN 10951) with the
Italian 3.6m TNG telescope (La Palma, Canary Islands) equipped with the
DOLORES camera operated in imaging mode. Observations started on Jul 13 at
21:25 UT (~6.8 after the GRB) and were carried out in R and I band for a
total exposure time of 900s and 540s, respectively. We do not detect any
source within the XRT error circle (D'Elia et al., GCN 10952) in both
filters down to a limiting magnitude of I~22.6 and R~23.6 (3sigma c.l.,
calibrated against the USNO B1 catalogue). We note the presence of a faint
source visible in both our images and the SDSS close to the the border of
the XRT error circle at the following coordinates (J2000):
R.A.=17:00:48.1
Dec=+28:23:45.7

with the 152 cm Cassini Telescope located in Loiano under clear sky conditions
(seeing approximately 2 arcsec).
One R-band observation (1x2400 sec) was done on 2010 July at 13.891 UT middle exposure time.
Comparison to the DSS (second epoch) reveals no new sources within the
INTEGRAL/IBAS error circle or the Swift/XRT error circle (D'Elia et al. 2010, GCN 10952).
Our 3-sigma limiting magnitude is R = 21 calibrated against the

FROM: Jochen Greiner at MPI
M. Nardini, T. Kruehler, and J. Greiner (all MPE Garching) report on behalf
of the GROND team:
We observed the field of GRB 100713A (INTEGRAL trigger 6041; Mereghetti et
al., GCN #10951) simultaneously in g'r'i'z'JHK with GROND (Greiner et al.
2008, PASP 120, 405) mounted at the 2.2 m MPI/ESO telescope at La Silla
Observatory (Chile).
Observations started at 23:46 UT on 2010 July 13th, 9.3 h after the GRB
trigger. They were performed at an average seeing of 2.6" and at an
average airmass of 2.5. With a total integration time of 13.2 min (12 min
for the IR), we do not detect any source within the Swift-XRT error circle
reported by D'Elia et al. (GCN #10952) down to
g' > 23.8,
r' > 22.9,
i' > 22.0,
z' > 21.5,
J > 18.8,
H > 17.4 and
K > 16.8
The given limits are derived based on calibrating the images against USNO
B1 catalogue and 2MASS field stars and are not corrected for the Galactic
foreground extinction corresponding to a reddening of E_(B-V)= 0.056 in
the direction of the burst (Schlegel et al. 1998).
We confirm the presence of a faint source close to the border of the XRT
error circle at the coordinates reported by D'Avanzo et al. (GCN 10954).

team report:
Swift/UVOT began settled observations of the INTEGRAL burst GRB100713A
(Mereghetti et al., GCN 10951) 6247s after the trigger.
At the position of the X-ray counterpart (D'Elia et al., GCN 10952), we do
not detect any optical afterglow in the exposures in UVOT filters down to
the following 3 sigma upper limits.
Filter T_start (s) T_stop (s) Exp (s) Mag upper limit

The values quoted above are calculated using the UVOT photometric system
(Poole et al 2008, MNRAS, 383, 627) and are not corrected for the Galactic
extinction due to the reddening of E(B-V) = 0.06 in the direction of the

A 3 sigma upper limits are the followings.
J > 18.9
H > 18.0

This photometry was done by using the DoPHOT and calibrated against

FROM: Valerio D'Elia at ASDC
V. D'Elia and G. Stratta (ASDC) report on behalf of the Swift-XRT team:
We have analysed 6.0 ks of XRT data for GRB100713A (D'Elia et al. GCN
Circ. 10952), from 6.23 to 52.3 ks after the INTEGRAL trigger
(Mereghetti et al. GCN Circ. 10951). The data
are entirely in Photon Counting (PC) mode. Using 1772 s of PC mode data
and 2 UVOT images, we find an enhanced XRT position (using the XRT-UVOT
alignment and matching UVOT field sources to the USNO-B1 catalogue):
RA, Dec = 255.20133, +28.39434 which is equivalent to:
RA (J2000): 17 00 48.32
Dec(J2000): +28 23 39.6
with an uncertainty of 2.4 arcsec (radius, 90% confidence).
The light curve can be modelled with a power-law decay with a decay
index of alpha=1.25 (-0.8+0.9).
A spectrum formed from the PC mode data can be fitted with an absorbed
power-law with a photon spectral index of 2.50 (+0.78, -0.68). The
best-fitting absorption column is 2.2 (+2.0, -1.3) x 10^21 cm^-2, in
excess of the Galactic value of 5.0 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 3.5 x 10^-11 (7.6 x 10^-10) erg
cm^-2 count^-1.
The results of the XRT-team automatic analysis are available at

We observed the field of the INTEGRAL GRB 100713A (Mereghetti et al. GCN
10951) with AZT-22 telescope of Maidanak observatory in R band between July
13 (UT) 18:21 -- 18:56 under photometric conditions and seeing ~0.7".
A possible faint source (S/N = 2.2) was detected at coordinates (J2000)
RA=17 00 48.12 Dec = +28 23 40.2 with uncertainties 0.15" in both
coordinates. The source is at the edge of enhanced XRT error circle (D'Elia

and comparison with TNG observation (D'Avanzo et al. GCN 10954) and/or
additional observation is necessary. The SDSS object reported by D'Avanzo et
al. (GCN 10954) and Nardini et al. (GCN 10956) is also clearly detected.

Since we do not detect the source observed at 3.75 hours after burst (GCN

candidate.
