Bissaldi (Politecnico and INFN Bari) and S. Lesage (UAH) report on behalf of the Fermi GBM Team: "At 05:30:08.21 UT on 13 June 2020, the Fermi Gamma-Ray Burst Monitor (GBM) triggered and located GRB 200613A (trigger 613719013 / 200613229). The Fermi GBM Final Real-time Localization is reported in GCN #27926. The angle from the Fermi LAT boresight at the GBM trigger time is 25 degrees. The GBM light curve shows a bright initial emission episode followed by a later weaker emission episode with a duration (T90) of about 470 s (50-300 keV). The time-averaged spectrum from T0 to T0+50 s is best fit by a Band function with Epeak = 111 +/- 3 keV, alpha = -1.08 +/- 0.02, and beta = -2.58 +/- 0.08. The event fluence (10-1000 keV) in this time interval is (4.10 +/- 0.05)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+12.2 s in the 10-1000 keV band is 27.2 +/- 0.4 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog: https://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html For Fermi GBM data and info, please visit the official Fermi GBM Support Page: https://fermi.gsfc.nasa.gov/ssc/data/access/gbm/"

Kovacevic (INFN Perugia), E. Bissaldi (Politecnico & INFN Bari), M. Axelsson (KTH & Stockholm Univ.) and F. Longo (University and INFN, Trieste) report on behalf of the Fermi-LAT Collaboration: On June 13, 2020, Fermi-LAT detected high-energy emission from GRB 200613A, which was also detected by Fermi-GBM at T0 = 05:30:08 UT (GCN 27926, Bissaldi et al. GCN 27930). The GRB is detected at high energy (>100 MeV) by Fermi-LAT at a location of: RA, Dec = 153.03, 45.85 (degrees, J2000) with an error radius of 0.14 deg (90% containment, statistical error only). This was ~29 deg from the LAT boresight when observations started, and is ~5.9 deg from the GBM final ground position. The photon flux above 100 MeV in the time interval 0 - 10.000 s after the GBM trigger is 6.6e-07 +/- 3.6e-07 ph/cm2/s. The estimated photon index above 100 MeV is -1.73 +/- 0.36. The highest-energy photon is a 7.6 GeV event which is observed ~6.2 ks after the GBM trigger. A Swift ToO has been approved for this burst. The Fermi-LAT point of contact for this burst is Masanori Ohno ( ohno@astro.hiroshima-u.ac.jp). The Fermi-LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater than 300 GeV. It is the product of an international collaboration between NASA and DOE in the U.S. and many scientific institutions across France, Italy, Japan and Sweden.

Kann (HETH/IAA-CSIC), A. de Ugarte Postigo (HETH/IAA-CSIC, DARK/NBI), M. Blazek, C. Thoene, J. F. Agui Fernandez (all HETH/IAA-CSIC), A. Moreno, and H. Vasquez Ramio (both CEFCA) report: We observed the LAT position of the bright GRB 200613A (Fermi-LAT detection: Ohno et al. GCN #27931, Fermi GBM detection: Bissaldi & Lesage, GCN #27930) with the T80 0.8m telescope at the Observatorio de Javalambre (Teruel, Spain). Observations consisted of 3 x 300 s in g', 3 x 300 s in r', and 5 x 180 s in i'. At the position of the second reported XRT source, we detect an optical source not seen to several magnitudes deeper in PanSTARRS archival imaging. The source is detected in each frame. The position is RA (J2000) = 10:12:10.08, Dec. (J2000) = 45:54:14.26 with an estimated error of 0".5. There is also a cataloged SDSS source nearby at RA (J2000) = 10:12:10.075, Dec. (J2000) = 45:54:12.88, this may be the host galaxy of the GRB, though we note nothing is detected here in the PanSTARRS image. Further analysis is in progress. Spectroscopic observations are encouraged.

Circular_text TITLE: GCN CIRCULAR NUMBER: 27936 SUBJECT: GRB 200613A: Swift-XRT afterglow detection DATE: 20/06/14 04:46:25 GMT FROM: Kim Page at U.of Leicester J.A. Kennea (PSU), A. Tohuvavohu (U. Toronto), B. Sbarufatti (PSU), J.P. Osborne (U. Leicester), K.L. Page (U. Leicester), A. Melandri (INAF-OAB), T. Sbarrato (INAF-OAB), P. D'Avanzo (INAF-OAB) and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team: Swift-XRT has performed follow-up observations of the Fermi/LAT-detected burst GRB 200613A (Ohno et al. GCN Circ. 27931), collecting 4.9 ks of Photon Counting (PC) mode data between T0+43.6 ks and T0+67.6 ks. Seven uncatalogued X-ray sources are detected, of which one ("Source 2") is above the RASS limit, and is therefore likely the GRB afterglow. Using 4079 s of PC mode data and 4 UVOT images, we find an enhanced XRT position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 153.04199, +45.75408 which is equivalent to: RA (J2000): 10h 12m 10.08s Dec(J2000): +45d 45' 14.7" with an uncertainty of 1.4 arcsec (radius, 90% confidence). This position is 5.8 arcmin from the Fermi/LAT position. The light curve can be modelled with a power-law decay with a decay index of alpha=1.6 (+/-0.5). A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 1.89 (+0.14, -0.13). The best-fitting absorption column is 2.3 (+/-0.5) x 10^21 cm^-2, in excess of the Galactic value of 8.4 x 10^19 cm^-2 (Willingale et al. 2013). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.5 x 10^-11 (4.7 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 2.3 (+/-0.5) x 10^21 cm^-2 Galactic foreground: 8.4 x 10^19 cm^-2 Excess significance: 7.5 sigma Photon index: 1.89 (+0.14, -0.13) The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00021003.

Observations started on June 13th at 22:20:26 UT (0.701 days after the GRB trigger) and we obtained a series of 60s images in the r filter. We clearly detect in the stacked image the optical afterglow at the position reported by the Swift-XRT (Kennea et al., GCN #27936) and by OAJ, Kitab and AbAO (Kann et al., GCN #27935, GCN #27938; Pozanenko et al., GCN #27937). We measure a preliminary AB magnitude for the afterglow of r = 19.45 +- 0.20 mag (t_mid = 0.705 d) calibrated against Pan-STARRS catalogue stars.

Circular_text TITLE: GCN CIRCULAR NUMBER: 27944 SUBJECT: GRB 200613A: Swift/UVOT Detection DATE: 20/06/14 17:02:42 GMT FROM: Frank Marshall at Swift/UVOT F. E. Marshall (NASA/GSFC) reports on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 200613A 43621 s after the FERMI/LAT trigger (Ohno et al., GCN Circ. 27931). A source consistent with the XRT position (Kennea et al., GCN Circ. 27936) is detected in the initial UVOT exposures. The preliminary UVOT position is: RA (J2000) = 10:12:10.03 = 153.04178 (deg.) Dec (J2000) = +45:45:14.1 = 45.75391 (deg.) with an estimated uncertainty of 0.46 arc sec. (radius, 90% confidence). This position is consistent with the optical counterparts reported by Kann et al. (GCN Circ. 27935 & 27938) and Pozanenko (GCN Circ. 27937). Preliminary detections and 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the early exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white 44416 45204 775 19.65 +/- 0.07 v 45211 45427 213 >18.6 u 43621 44409 775 19.02 +/- 0.12 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.01 in the direction of the burst (Schlegel et al. 1998).

The burst signal was seen by all CGBM detectors. Because of a problem in one of the ground alert processing script, the GCN notice was not distributed automatically for this event. The burst light curve shows the main emission episode which starts at T-1 sec, peaks at T+11 sec and ends at T+35 sec, followed by a much weaker emission episode which starts at ~T+278 sec and ends at ~T+423 sec. The T90 and T50 durations measured by the SGM data are 381 +- 34 sec and 268 +- 237 sec (40-1000 keV), respectively. The ground processed light curve is available at http://cgbm.calet.jp/cgbm_trigger/ground/1276061388/ The CALET data used in this analysis are provided by the Waseda CALET Operation Center located at the Waseda University.

The observation was performed on the 18 January 2021 with mean epoch at 00:02 UT (218.75 days after the burst) and consisted of 3x1200s exposures with grism R1000R, covering the range between 5100 and 10100 Ã…. The spectrum is characterised by a continuum that is detected over the complete spectral range, with better SNR in the blue part of the spectrum, and has a strong emission feature that we identify as the [OII] 3727/3729 doublet, at a redshift of 1.2280. At a similar redshift of 1.2255 we also identify absorptions due to FeII and MgII, that allow us to confirm the redshift, which we identify as that of GRB 200613A.
