Sugizaki (NAOC) report on behalf of the MAXI team: The MAXI/GSC nova alert system triggered on a bright uncatalogued X-ray transient source at 2022-03-10T00:27:57 UT. Assuming that the source flux was constant over the transit, we obtain the source position at (R.A., Dec) = (168.612 deg, 23.451 deg) = (11 14 26, +23 27 03) (J2000) with a 90% C.L. statistical error of 0.16 deg and an additional systematic uncertainty of 0.1 deg (90% containment radius). Without assumptions on the source constancy, we obtain a rectangular error box for the transient source with the following corners: (168.038, 23.325) deg = (11 12 09, +23 19 29) (J2000) (168.176, 23.093) deg = (11 12 42, +23 05 34) (J2000) (169.335, 23.670) deg = (11 17 20, +23 40 12) (J2000) (169.197, 23.903) deg = (11 16 47, +23 54 10) (J2000) The X-ray flux averaged over the scan was 348 +- 37 mCrab (4.0-10.0keV, 1 sigma error). There was no significant excess flux in the previous transit at 3/9 22:55 UT with an upper limit of 20 mCrab.

The T90 and T50 durations measured by the SGM data are 33.1 +- 8.3 sec and 12.9 +- 1.2 sec (40-1000 keV), respectively. The ground processed light curve is available at http://cgbm.calet.jp/cgbm_trigger/ground/1330907255/ The CALET data used in this analysis are provided by the Waseda CALET Operation Center located at the Waseda University.

Leicester) reports on behalf of the Swift team: Swift has initiated a ToO observation of the MAXI GRB 220310A. Automated analysis of the XRT data will be presented online at https://www.swift.ac.uk/ToO_GRBs/00021482 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 MAXI 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: 31738 SUBJECT: GRB 220310A: GIT confirmation of optical afterglow. DATE: 22/03/11 10:23:08 GMT FROM: Harsh Kumar at Indian Inst of Tech,Bombay H. Kumar (IITB), J. Stanzin (IAO), V. Bhalerao (IITB), G. C. Anupama (IIA), S. Barway (IIA) report on behalf of the GIT team: We observed GRB 220310A detected by MAXI/GSC H. Negoro et al., (GCN #31725) and optical afterglow discovered by V. Lipunov (GCN #31732), with 0.7m GROWTH-India Telescope (GIT). We obtained multiple 300-sec exposures in the g',r' and i' filters. We clearly detected the afterglow in our stacked image. The photometric results follow as: ------------------------------------------------------------------- JD (mid) | T_mid-T0(days) | Filter | Magnitude (AB) | ------------------------------------------------------------------- 2459649.085963 | 0.566 | g' | 19.86 +/- 0.03 2459649.093405 | 0.574 | r' | 19.45 +/- 0.04 2459649.100833 | 0.581 | i' | 19.11 +/- 0.04 2459649.327412 | 0.810 | g' | 20.66 +/- 0.08 2459649.334752 | 0.815 | r' | 20.21 +/- 0.07 2459649.342128 | 0.823 | i' | 19.70 +/- 0.09 ------------------------------------------------------------------- On the basis of fading seen in our observations, we confirm the MASTER OT J111302.33+231508.0 (GCN #31732) as an afterglow of GRB 220310A. Further, using our r'-band data, we estimated the index of power-law decay index = 1.99 +/- 0.17. The magnitudes are calibrated against PanSTARRS DR1 (Chambers et al., 2016) and not corrected for Galactic extinction. The GROWTH India Telescope (GIT) is a 70-cm telescope with a 0.7-degree field of view, set up by the Indian Institute of Astrophysics (IIA) and the Indian Institute of Technology Bombay (IITB) with funding from DST-SERB and IUSSTF. It is located at the Indian Astronomical Observatory (Hanle), operated by IIA. We acknowledge funding by the IITB alumni batch of 1994, which partially supports operations of the telescope.

Circular_text TITLE: GCN CIRCULAR NUMBER: 31748 SUBJECT: Konus-Wind detection of GRB 220310A DATE: 22/03/12 08:25:44 GMT FROM: Dmitry Svinkin at Ioffe Institute D. Svinkin, D. Frederiks, M. Ulanov, A. Tsvetkova, A. Lysenko, A. Ridnaia, and T. Cline on behalf of the Konus-Wind team, report: The long-duration GRB 220310A (MAXI/GSC detection: Negoro et al., GCN Circ. 31725; CALET-CGBM detection: Negoro et al., GCN Circ. 31730) triggered Konus-Wind at T0=1702.557 s UT (00:28:22.557). The burst light curve shows an initial weak episode which starts at ~T0-24 s and ends at ~T0-12 s, followed by a brighter multipeaked structure seen up to ~T0+37 s. The total burst duration is ~61 s. The emission is seen up to ~7 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB220310_T01702/ As observed by Konus-Wind, the burst had a fluence of 3.15(-0.46,+0.54)x10^-5 erg/cm2, and a 64-ms peak flux, measured from T0+14.144 s, of 2.32(-0.62,+0.62)x10^-6 erg/cm2/s (both in the 20 keV - 10 MeV energy range). The time-averaged spectrum of the burst (measured from T0 to T0+41.216 s) is best fit in the 20 keV - 8 MeV range by the GRB (Band) model with the following parameters: the low-energy photon index alpha = -0.49(-0.37,+0.61), the high energy photon index beta = -2.47(-0.67,+0.25), the peak energy Ep = 138(-27,+32) keV (chi2 = 75/85 dof). The spectrum near the maximum count rate (measured from T0+8.448 s to T0+16.640 s) is best fit in the 20 keV - 8 MeV range by a power law with exponential cutoff model: with alpha = -0.70(-0.24,+0.28) and Ep = 168(-18,+23) keV (chi2 = 67/75 dof). Fitting by a GRB (Band) model yields the same alpha and Ep, and an upper limit on the high energy photon index: beta < -2.5 (chi2 = 67/74 dof). All the quoted errors are at the 90% confidence level. All the quoted values are preliminary.

Fouad, Ali Takey, Mona Molham, Saad Ata, Ola Ali (NRIAG) report: We observed the optical counterpart of GRB 220310A (H. Negoro et al., GCN 31725) using a 1.88-m telescope at the Kottamia Astronomical Observatory (KAO), NRIAG, Egypt. The source was visible at the position discovered by (V. Lipunov et al., GCN 31732) where the SDSS galaxy (ObjID: 1237667910586532614) is located. KAO observations started from 22:05:22 to 23:06:00 UT on 10-03-2022, ~ 21.5 hrs after the MAXI/GSC trigger. The combined images of 10 x 150sec were created for SDSS r,i images. We report the preliminary photometry as: -------------------------------------------------------- Object / r-mag / r-err / i-mag / i-err -------------------------------/------------/-----------/------------/--------- GRB220310A by KAO / 19.723 / 0.141 / 19.727 / 0.090 Published SDSS-gal. / 21.94 / 0.19 / 21.62 / 0.22 ------------------------------------------------------------------------------- Aperture photometry was done based on 9 stars around the GRB in a FoV = 8' x 8', selected from the SDSS-DR16. The magnitude is not corrected for Galactic extinction in the direction of the GRB.

Gardner on on behalf of the GRS-Odyssey GRB team, report: The long-duration GRB 220310A (MAXI/GSC detection: Negoro et al., GCN Circ. 31725; CALET-CGBM detection: Yoshida et al., GCN Circ. 31730; Konus-Wind detection: Svinkin et al., GCN Circ. 31748) was detected by MAXI(GSC), CALET (GBM), Konus-Wind, and Mars-Odyssey (HEND) at about 1702 s UT (00:28:22). We have triangulated it to a Konus-HEND annulus centered at RA(2000)=124.878 deg (08h 19m 31s) Dec(2000)=+20.557 deg (+20d 33' 25"), whose radius is 40.183 +/- 0.041 deg (3 sigma). The MAXI/GSC localization is consistent with the annulus. The position of the optical transient J111302.33+231508.0 (Lipunov et al., GCN Circ. 31732) is inside the annulus at 0.7 arcmin from its center line. The positional and temporal coincidence of this burst with the OT supports the conclusion that the OT is the GRB counterpart.
