Circular_text TITLE: GCN CIRCULAR NUMBER: 19059 SUBJECT: GRB 160223B: A long GRB detected by INTEGRAL DATE: 16/02/23 10:54:09 GMT FROM: Diego Gotz at CEA D.Gotz (CEA, Saclay), S.Mereghetti (IASF-Milano), C.Ferrigno, E.Bozzo, S. Fotopoulou(ISDC, Versoix), and J.Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: a gamma ray burst lasting about 30 s has been detected by IBAS in the IBIS/ISGRI data at 09:58:58 UT of February 23, 2016. The refined coordinates (J2000) are: R.A.= 94.9937 deg DEC.= +33.4075 deg with an uncertainty of 2.2 arcmin (90% c.l.). The burst had a peak flux of 1.2 counts/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 1.6e-6 erg/cmsq. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html

Circular_text TITLE: GCN CIRCULAR NUMBER: 19060 SUBJECT: GRB 160223B: Swift ToO observations DATE: 16/02/23 12:55:22 GMT FROM: Phil Evans at U of Leicester P. A. Evans (U. Leicester) reports on behalf of the Swift team: Swift has initiated a ToO observation of the INTEGRAL GRB 160223B. Automated analysis of the XRT data will be presented online at http://www.swift.ac.uk/ToO_GRBs/00020601 Any uncatalogued X-ray sources detected in this analysis will be reported on this website and via GCN COUNTERPART notices. These are not necessarily related to the INTEGRAL event. Any X-ray source considered to be a probable afterglow candidate will be reported via a GCN Circular after manual consideration. Details of the XRT automated analysis methods are detailed in Evans et al. (2007, A&A, 469, 379; 2009, MNRAS, 397, 1177 and 2014, ApJS, 210, 8).

Circular_text TITLE: GCN CIRCULAR NUMBER: 19061 SUBJECT: GRB 160223B: Fermi GBM observation DATE: 16/02/23 15:27:58 GMT FROM: Andreas von Kienlin at MPE A. von Kienlin, H.-F. Yu, and K. Toelge (all MPE) report on behalf of the Fermi GBM Team: "At 09:59:01.51 UT on 23 February 2016, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 160223B (trigger 477914345 / 160223416), which was also detected by INTEGRAL (Götz et al. 2016, GCN 19059) The GBM on-ground location is consistent with the INTEGRAL position. The angle from the Fermi LAT boresight at the GBM trigger time is 49 degrees. The GBM light curve shows a structured pulse with a duration (T90) of about 17 s (50-300 keV). The time-averaged spectrum from T0-2.560 s to T0+16.896 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.90 (+0.08/-0.07) and the cutoff energy, parameterized as Epeak, is 560 (+110 /-80) keV The event fluence (10-1000 keV) in this time interval is (5.9 +/- 0.3)E-06 erg/cm^2. The 1.024-sec peak photon flux measured starting from T0+0.256 s in the 10-1000 keV band is 3.1 +/- 0.2 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

McCauley (PSU), J.A. Kennea (PSU), S.L. Gibson (U. Leicester), J.P. Osborne (U. Leicester), K.L. Page (U. Leicester), P. D'Avanzo (INAF-OAB), V. D'Elia (ASDC), A. D'Ai (INAF-IASFPA) and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team: Swift-XRT has performed follow-up observations of the INTEGRAL-detected burst GRB 160223B (Gotz et al. GCN Circ. 19059), collecting 2.3 ks of Photon Counting (PC) mode data between T0+10.6 ks and T0+16.4 ks. No X-ray sources have been detected inside or close to the INTEGRAL error region. The 3-sigma upper limit in the field ranges from ~0.004 to ~0.005 ct s^-1, corresponding to a 0.3-10 keV observed flux of 1.8e-13 to 1.9e-13 erg cm^-2 s^-1 (assuming a typical GRB spectrum). The results of the XRT-team automatic analysis of the XRT observations, including a position-specific upper limit calculator, are available at http://www.swift.ac.uk/ToO_GRBs/00020601.

Schmalz (ISON), A. Volnova (IKI), N. Tungalag (Research Center of Astronomy and Geophysics MAS), I. Molotov (KIAM), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed the field of INTEGRAL and Fermi GRB 160223B GRB 160223B (Gotz et al. GCN 19059; von Kienlin et al., GCN 19061) with ORI-40 telescope of Khureltogot observatory starting on Feb., 23 (UT) 12:34:31. Within 2.2 arcmin error circle of the GRB 160223B localization (Gotz et al., GCN 19059) we marginally detect two possible sources not presented in USNO-B1.0 catalog. Coordinates of the sources are Source (1): (J2000) 6:20:05.53 +33:24:58.7 Source (2): (J2000) 6:20:03.89 +33:23:14.2 with uncertainties of 1 arcsec in both coordinates. At this time we cannot confirm the sources are real or variable due to low S/N and absence of a full dataset. Preliminary photometry of the sources is following Date UT start t-T0 Filter Exp.

The burst signal was detected by SGM instrument. The light curve of the SGM shows at least three peaks. The emission starts at T0, peaks at T0+1 sec and ends at T0+25 sec.
