Circular_text TITLE: GCN CIRCULAR NUMBER: 35770 SUBJECT: GRB 240222A: Swift detection of a burst DATE: 24/02/22 09:04:46 GMT FROM: Paolo D'Avanzo at INAF - OAB P. D'Avanzo (INAF-OAB), R. Brivio (INAF-OAB), S. Dichiara (PSU), A. Y. Lien (U Tampa), K. L. Page (U Leicester), C. Salvaggio (INAF-OAB), T. Sbarrato (INAF-OAB) and B. Sbarufatti (INAF-OAB) report on behalf of the Neil Gehrels Swift Observatory Team: At 08:51:31 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 240222A (trigger=1216804). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 143.248, -68.029 which is RA(J2000) = 09h 32m 59s Dec(J2000) = -68d 01' 43" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a multi-peaked structure with a duration of about 20 sec. The peak count rate was ~3000 counts/sec (15-350 keV), at ~0 sec after the trigger. The XRT began observing the field at 08:53:05.3 UT, 94.0 seconds after the BAT trigger. Using promptly downlinked data we find a fading, uncatalogued X-ray source located at RA, Dec 143.22556, -68.03102 which is equivalent to: RA(J2000) = 09h 32m 54.13s Dec(J2000) = -68d 01' 51.7" with an uncertainty of 3.5 arcseconds (radius, 90% containment). This location is 31 arcseconds from the BAT onboard position, within the BAT error circle. This position may be improved as more data are received; the latest position is available at https://www.swift.ac.uk/sper. A power-law fit to a spectrum formed from promptly downlinked event data gives a column density in excess of the Galactic value (1.72 x 10^21 cm^-2, Willingale et al. 2013), with an excess column of 4.6 (+3.44/-2.96) x 10^21 cm^-2 (90% confidence). UVOT took a finding chart exposure of 150 seconds with the White filter starting 98 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers 100% of the XRT error circle. The typical 3-sigma upper limit has been about 19.6 mag. The 8'x8' region for the list of sources generated on-board covers 100% of the XRT error circle. The list of sources is typically complete to about 18 mag. No correction has been made for the expected extinction corresponding to E(B-V) of 0.166. Burst Advocate for this burst is P. D'Avanzo (paolo.davanzo AT inaf.it). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/)

Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team: "At 08:51:31.47 UT on 22 February 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240222A (trigger 730284696/240222369). which was also detected by Swift BAT (P. D'Avanzo et al. 2024, GCN 35770). The Fermi GBM on-ground location is consistent with the Swift BAT position. The angle from the Fermi LAT boresight is 109 degrees. The GBM light curve consists of a single emission episode with a duration (T90) of about 3.8 s (50-300 keV). The time-averaged spectrum from T0-5.9 to T0+3.3 s is best fit by a simple power law function with index -1.4 +/- 0.1. The event fluence (10-1000 keV) in this time interval is (9.2 +/- 1.9)E-07 erg/cm^2. The 1-sec peak photon flux measured starting from T0-0.19 s in the 10-1000 keV band is 4 +/- 0.7 ph/s/cm^2.

Brivio (INAF-OAB), A. D'Ai (INAF-IASFPA), A. Melandri (INAF-OAR), S. Dichiara (PSU), J.A. Kennea (PSU), A. Tohuvavohu (U. Toronto), J.P. Osborne (U. Leicester) and P.A. Evans report on behalf of the Swift-XRT team: We have analysed 6.6 ks of XRT data for GRB 240222A, from 106 s to 41.2 ks after the BAT trigger. The data comprise 9 s in Windowed Timing (WT) mode (taken while Swift was slewing), with the remainder in Photon Counting (PC) mode. The refined XRT position is RA, Dec = 143.2254, -68.0305 which is equivalent to: RA (J2000): 09 32 54.10 Dec(J2000): -68 01 49.7 with an uncertainty of 3.5 arcsec (radius, 90% confidence). The light curve can be modelled with a power-law decay with a decay index of alpha=2.02 (+0.12, -0.11). A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 1.52 (+0.24, -0.12). The best-fitting absorption column is consistent with the Galactic value of 1.7 x 10^21 cm^-2 (Willingale et al. 2013). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 4.6 x 10^-11 (5.3 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 1.7 (+/-0.9) x 10^21 cm^-2 Galactic foreground: 1.7 x 10^21 cm^-2 Excess significance: <1.6 sigma Photon index: 1.52 (+0.24, -0.12) If the light curve continues to decay with a power-law decay index of 2.02, the count rate at T+24 hours will be 1.3 x 10^-5 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 5.8 x 10^-16 (6.7 x 10^-16) erg cm^-2 s^-1. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/01216804. This circular is an official product of the Swift-XRT team.

Sakamoto (AGU) (i.e. the Swift-BAT team): Using the data set from T-60 to T+243 sec from the recent telemetry downlink, we report further analysis of BAT GRB 240222A (trigger #1216804) (D'Avanzo et al., GCN Circ. 35770). The BAT ground-calculated position is RA, Dec = 143.209, -68.034 deg which is RA(J2000) = 09h 32m 50.2s Dec(J2000) = -68d 02' 03.7" with an uncertainty of 1.8 arcmin, (radius, sys+stat, 90% containment). The partial coding was 94%. The mask-weighted light curve shows a main pulse that starts at ~T-0.4 s, peaks at ~T0, and ends at ~T+1.4 s. In addition, there is a small precursor pulse at ~T-2.7 s. T90 (15-350 keV) is 3.94 +- 2.35 sec (estimated error including systematics). The time-averaged spectrum from T-2.70 to T+1.37 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 0.75 +- 0.23. The fluence in the 15-150 keV band is 2.5 +- 0.3 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T-0.20 sec in the 15-150 keV band is 1.3 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

Proc. SPIE 2018). The detector of GRBAlpha consists of a 75 x 75 x 5 mm3 CsI scintillator read out by a SiPM array, covering the energy range from ~50 keV to ~1000 keV. To increase the duty cycle and the downlink rate, the upgrade of the on-board data acquisition software stack is in progress. The ground segment is also supported by the radio amateur community and it takes advantage of the SatNOGS network for increased data downlink volume.

Circular_text TITLE: GCN CIRCULAR NUMBER: 35801 SUBJECT: GRB 240222A: ATCA radio observations DATE: 24/02/26 17:22:04 GMT FROM: jamesk.leung@utoronto.ca J. K. Leung (U. Toronto/HUJI), G. E. Anderson (Curtin University), S. Chastain (UNM), A. Gulati (U. Sydney), L. Rhodes (U. Oxford), A. J. van der Horst (GWU) on behalf of the PanRadio GRB collaboration The Australia Telescope Compact Array (ATCA) performed observations of GRB 240222A (Fermi GBM Team, GCN 35769; D'Avanzo et al., GCN 35770) at 5.5, 9, 16.7 and 21.2 GHz as part of the Large ATCA "PanRadio GRB" follow-up programme C3542 (PI. Anderson). ATCA observed from 2024-02-24 12:00 UT to 22:00 UT. In our preliminary analysis, we find no radio source coincident with the refined XRT position (Beardmore et al., GCN 35780) with 3 sigma upper limits of 75, 54, 69 and 159 microJy/beam at 5.5, 9.0, 16.7 and 21.2 GHz, respectively. We thank the CSIRO Space and Astronomy staff for supporting these observations. We acknowledge the Gomeroi people as the traditional owners of the Observatory site. The Australia Telescope Compact Array is part of the Australia Telescope National Facility (https://ror.org/05qajvd42) which is funded by the Australian Government for operation as a National Facility managed by CSIRO.
