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.

Burenin, (IKI), I. Khamitov (TUG), M. Pavlinsky, R. Sunyaev (IKI), Z. Eker (TUG), U. Kiziloglu (METU), E. Gogus (Sabanci Uni.), I. Bikmaev, N. Sakhibullin (KSU/AST) 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. _______________________________________________ Aavso-hen mailing list Aavso-hen(emailaddressremoved) http://www.aavso.org/mailman/listinfo/aavso-hen Date: Thu, 17 Apr 2008 09:02:38 -0400 Message-Id: <200804171302.m3HD2c0w031696(emailaddressremoved)> To: aavso-hen(emailaddressremoved) From: grb(emailaddressremoved) Subject: [AAVSO-HEN] Swift XRT and UVOT observations of GRB080414 X-BeenThere: aavso-hen(emailaddressremoved) X-Mailman-Version: 2.1.9 Precedence: list List-Id: AAVSO High Energy Network List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: aavso-hen-bounces(emailaddressremoved) Errors-To: aavso-hen-bounces(emailaddressremoved) The following is a GCN Circular circulated via the AAVSO network.

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+56ks 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). _______________________________________________ Aavso-hen mailing list Aavso-hen(emailaddressremoved) http://www.aavso.org/mailman/listinfo/aavso-hen Date: Fri, 18 Apr 2008 08:41:21 -0400 Message-Id: <200804181241.m3ICfLZs009084(emailaddressremoved)> To: aavso-hen(emailaddressremoved) From: grb(emailaddressremoved) Subject: [AAVSO-HEN] GCN Report 125.1: Final Swift Observations of INTEGRAL GRB 080414 X-BeenThere: aavso-hen(emailaddressremoved) X-Mailman-Version: 2.1.9 Precedence: list List-Id: AAVSO High Energy Network List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: aavso-hen-bounces(emailaddressremoved) Errors-To: aavso-hen-bounces(emailaddressremoved) The following is a GCN Circular circulated via the AAVSO network.
