S.Mereghetti, A.Paizis (IASF-Milano), D.Gotz (CEA-Saclay), M. Turler,
S.Shaw, M. Beck, C. Baldovin Saavedra (ISDC, Versoix), and J.
Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report:
A GRB lasting about 10 s has been detected by IBAS in IBIS/ISGRI data at
22:33:32 UT of April 14. The coordinates (J2000) are:
RA: 272.1342 [degrees]
DEC: -18.8291 [degrees]
with an uncertainty of 2 arcmin (90% c.l.).
A preliminary analysis gives a peak flux in the 20-200 keV range of about
1 ph/cmq/s (1-s integration time) and a fluence over the same energy range
of 3e-7 erg/cmq.

FROM: Petr Kubanek at AIO
P. Kubanek (IAA-CSIC Granada, GACE Valencia) and J. French (UCD Dublin)
reports on behalf of the Watcher collaboration:
Watcher started observations of long INTEGRAL GRB at 22:36:25, e.g. 2:50
post GRB, 33 sec post GCN trigger. Observation, as well as futher
analysis, is ongoing. Quick look on first images does not show any new
source down to 14 mag.

report:
The field of the long GRB 080414 detected by INTEGRAL (Mereghetti et al.,
GCN 7618) was observed with Russian-Turkish 1.5-m telescope (RTT150,
Bakirlitepe, TUBITAK National Observatory, Turkey), under not optimal
conditions. We made 8x100s images in R band centered at 23:46 UT,
i.e. approximately 1.21 hours after the burst. We detect no new objects as
compared to DSS-II red plate with magnitude brighter than R=~20.

SUBJECT: Swift XRT and UVOT observations of GRB080414
DATE: 08/04/17 13:01:50 GMT
FROM: Massimiliano de Pasquale at MSSL-UCL
M. De Pasquale (MSSL/UCL), A.P. Beardmore (U. Leicester) and M.
Stamatikos (GSFC) report on the behalf of the Swift team:
At 2008-04-15 14:15UT Swift performed a TOO observation of the INTEGRAL
burst GRB 080414 (Mereghetti et al., GCN Circ. 7618), some 56.6ks after
the trigger.
No X-ray source was found in or near the IBAS error circle in a 3.9ks
exposure Swift/XRT Photon Counting mode image (taken from T+56.6ks to
T+85.5ks after the trigger) down to a 3 sigma limiting 0.3-10keV count
rate of 3e-3 count/s. Assuming a power-law spectrum of photon index 2
absorbed by the Galactic column density of 1.16e22 cm^-2 in the direction
of the burst, this corresponds to an observed 0.3-10keV flux limit of
1.9e-13 erg cm^-2 s^-1.
The Swift/UVOT also observed the field. We do not detect an UV/Optical
afterglow in the IBAS error circle in all UVOT filters down to the
following 5 sigma upper limits:
Filter T_start T_stop Exp. Mag UL (5sig)
(ks) (ks) (s)
v 56.9 79.9 272 > 18.3
b 56.7 79.5 272 > 19.4
u 56.7 84.7 326 > 19.2
uvw1 56.6 84.7 1001 > 19.9
uvm2 57.0 80.1 564 > 19.4
uvw2 56.8 79.8 1085 > 19.9
These upper limits are not corrected for the very large Galactic
extinction in the line of sight to GRB 080414, corresponding to a
reddening of E(B-V)=6.95 mag (Schlegel et al., 1998, ApJS, 500, 525). We
note that this value is rather uncertain in this direction.
The photometry is based on the UVOT photometric system described in Poole
et al. (2008, MNRAS, 383, 627).
[GCN OPS NOTE(17apr08): Per author's request, the "T+56ks to T+85.5ks"
was changed to "T+56.6ks to T+85.5ks".]
