Morii (ISM) report on behalf of the MAXI team: The MAXI/GSC nova alert system triggered a bright uncatalogued X-ray transient source at 03:39:16 UT on 2016 January 2. Assuming that the source flux was constant over the transit, we obtain the source position at (R.A., Dec) = (80.840 deg, -21.041 deg) = (05 23 21, -21 02 27) (J2000) with a statistical 90% C.L. elliptical error region and with long and short radii of 0.19 deg and 0.14 deg, respectively. The roll angle of long axis from the north direction is 180.0 deg counterclockwise. Theres an additional systematic uncertainty of 0.1 deg (90% containment radius). The X-ray flux averaged over the scan was 265 +- 32 mCrab (4-10keV, 1 sigma error). Without assumptions on the source constancy,we obtain a rectangular error box for the transient source with the following corners: (80.157 deg, -20.852 deg) = (05 20 37, -20 51 07) (J2000) (80.155 deg, -21.225 deg) = (05 20 37, -21 13 28) (J2000) (81.765 deg, -21.221 deg) = (05 27 03, -21 13 16) (J2000) (81.756 deg, -20.849 deg) = (05 27 01, -20 50 55) (J2000) There was no significant excess flux in the previous transit at UT 02:06 with an upper limit of 20 mCrab for each.

Circular_text	TITLE: GCN CIRCULAR NUMBER: 18802 SUBJECT: GRB 160102A: Tiled Swift observations DATE: 16/01/02 06:41:16 GMT FROM: Phil Evans at U of Leicester P. A. Evans (U. Leicester) reports on behalf of the Swift team: Swift has initiated a series of observations, tiled on the sky, of the MAXI GRB 160102A. Automated analysis of the XRT data will be presented online at http://www.swift.ac.uk/xrt_products/TILED_GRB00052 Any uncatalogued X-ray sources detected in this analysis will be reported on this website and via GCN COUNTERPART notices. The probability of finding serendipitous sources, unrelated to the MAXI event is high: 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: 18808 SUBJECT: GRB 160102A: Swift-XRT observations DATE: 16/01/02 20:27:05 GMT FROM: Valerio D'Elia at ASDC V. D'Elia (ASDC), L. Izzo (URoma/ICRA), L.M. McCauley (PSU), J.A. Kennea (PSU), B. Sbarufatti (INAF-OAB/PSU), S.L. Gibson (U. Leicester), J.P. Osborne (U. Leicester), A. D'Ai (INAF-IASFPA), A. Maselli (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 MAXI-detected burst GRB 160102A (Itoh et al. GCN Circ. 18801) in a series of observations tiled on the sky. The total exposure time is 1.8 ks, distributed over 7 tiles; the maximum exposure at a single sky location was 597 s. The data were collected between T0+10.8 ks and T0+17.0 ks, and are entirely in Photon Counting (PC) mode. No X-ray sources have been detected. The 3-sigma upper limit in the field (not including the regions where the tiles overlap) ranges from ~0.03 to ~0.07 ct s^-1, corresponding to a 0.3-10 keV observed flux of 1.0e-12 to 2.8e-12 erg cm^-2 s^-1 (assuming a typical GRB spectrum). The results of the XRT-team automatic analysis of the tiled XRT observations, including a position-specific upper limit calculator, are available at http://www.swift.ac.uk/xrt_products/TILED_GRB00052.

Circular_text	TITLE: GCN CIRCULAR NUMBER: 18867 SUBJECT: Konus-Wind observation of GRB 160102A DATE: 16/01/14 14:15:32 GMT FROM: Dmitry Svinkin at Ioffe Institute S. Golenetskii, R.Aptekar, D. Frederiks, P. Oleynik, M. Ulanov, D. Svinkin, A. Tsvetkova, A.Lysenko, A. Kozlova, and T. Cline on behalf of the Konus-Wind team, report: GRB 160102A, localized by MAXI/GSC (Itoh et al., GCN 18801), was detected by Konus-Wind in the waiting mode. The burst light curve shows a single pulse started at ~T0(MAXI)-3.6 s with a total duration of ~6 s or less. Due to the coarse resolution of the waiting mode light curve we cannot unambiguously classify this GRB as a short. As observed by Konus-Wind, the burst had a fluence of 8.66(-1.23,+3.01)x10^-7 erg/cm2 and a 2.944-s peak flux, measured from ~T0(MAXI)-0.668 s, of 1.49(-0.62,+0.78)x10^-7 erg/cm2/s (both in the 20 - 1500 keV energy range). Fitting the K-W 3-channel time-integrated spectrum (from ~T0(MAXI)-3.6 s to ~T0(MAXI)+2.28 s) by a simple power-law model yields a power law index of -2.05(-0.15,+0.23), chi2=0.5/1 dof. All the quoted errors are estimated at the 1 sigma confidence level. All the presented results are preliminary. The K-W light curve of this burst is available at http://www.ioffe.rssi.ru/LEA/GRBs/GRB160102A/
