Circular_text TITLE: GCN CIRCULAR NUMBER: 38234 SUBJECT: GRB 241115A: Fermi GBM Final Real-time Localization DATE: 24/11/15 13:28:56 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 13:18:24 UT on 15 Nov 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241115A (trigger 753369509.732778 / 241115554). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 85.2, Dec = 2.7 (J2000 degrees, equivalent to J2000 05h 40m, 2d 42'), with a statistical uncertainty of 6.0 degrees. The angle from the Fermi LAT boresight is 43.0 degrees.

Circular_text TITLE: GCN CIRCULAR NUMBER: 38235 SUBJECT: GRB 241115A: Swift detection of a burst DATE: 24/11/15 13:36:51 GMT FROM: K.L. Page at U Leicester M. A. Williams (PSU), J. J. DeLaunay (PSU), S. Dichiara (PSU), R. Gupta (NASA GSFC), K. L. Page (U Leicester) and D. M. Palmer (LANL) report on behalf of the Neil Gehrels Swift Observatory Team: At 13:18:25 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 241115A (trigger=1267921). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 86.765, -0.662 which is RA(J2000) = 05h 47m 04s Dec(J2000) = -00d 39' 44" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single-peaked structure with a duration of about 5 sec. The peak count rate was ~7600 counts/sec (15-350 keV), at ~1 sec after the trigger. The XRT began observing the field at 13:20:14.5 UT, 109.5 seconds after the BAT trigger. Using promptly downlinked data we find a fading, uncatalogued X-ray source located at RA, Dec 86.77049, -0.67381 which is equivalent to: RA(J2000) = 05h 47m 04.92s Dec(J2000) = -00d 40' 25.7" with an uncertainty of 3.5 arcseconds (radius, 90% containment). This location is 46 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 (3.32 x 10^21 cm^-2, Willingale et al. 2013), with an excess column of 9.4 (+6.11/-4.63) x 10^21 cm^-2 (90% confidence). UVOT took a finding chart exposure of 150 seconds with the White filter starting 113 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 1.028. Burst Advocate for this burst is M. A. Williams (mjw6837 AT psu.edu). 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/)

Strausbaugh (Eastern Illinois University), A. Cucchiara (NASA) report on behalf of a larger collaboration: We observed the Swift GRB 241115A field (Williams et al., GCN 38235) with the LCOGT 1-meter Sinistro instrument at the South African Astronomical Observatory site, on November 15, from 21:52 to 22:24 UT (corresponding to 8.57 to 9.10 hours after the GRB trigger time) with the sdss r and i filters. We performed a series of 3x300s exposures in i- and r-bands. We do not detect a source within the Swift XRT error region in either band. The following 5-sigma upper limits are calculated using the PanSTARRS catalog as reference: r > 21.5 i > 21.2 These magnitudes are not corrected for galactic extinction.

Dafčíková (Masaryk U.), and C. Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team: "At 13:18:24.73 UT on 15 November 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241115A (trigger 753369509/241115554). which was also detected by Swift BAT (M. A. Williams et al. 2024, GCN 38235). The Fermi GBM on-ground location is consistent with the Swift BAT position. The angle from the Fermi LAT boresight is 46 degrees. The GBM light curve consists of a single emission episode with a duration (T90) of about 3.1 s (50-300 keV). The time-averaged spectrum from T0-3.4 to T0+5.8 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.7 +/- 0.1 and the cutoff energy, parameterized as Epeak, is 90 +/- 7 keV. The event fluence (10-1000 keV) in this time interval is (1.57 +/- 0.08)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+0.32 s in the 10-1000 keV band is 7.7 +/- 0.3 ph/s/cm^2. A Band function fits the spectrum equally well with Epeak= 80 +/- 9 keV, alpha = -0.6 +/- 0.2 and beta = -2.7 +/- 0.4. 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/"

Multiple frames with 180s and 50s exposures in uvgr bands were taken.

D'Ai (INAF-IASFPA), A. Melandri (INAF-OAR), D.N. Burrows (PSU), M. A. Williams (PSU), S. Dichiara (PSU), J.P. Osborne (U. Leicester), K.L. Page (U. Leicester) and P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team: Swift-XRT has performed follow-up observations of the Swift-BAT-detected burst GRB 241115A, collecting 11.3 ks of Photon Counting (PC) mode data between T0+92 s and T0+102.8 ks. An uncatalogued X-ray source is detected consistent with being within 296 arcsec of the Swift-BAT position and is above the RASS 3-sigma upper limit at this position and fading with >3-sigma significance, and is therefore likely the GRB afterglow. Using 2620 s of PC mode data and 5 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 = 86.77097, -0.67462 which is equivalent to: RA (J2000): 05h 47m 05.03s Dec(J2000): -00d 40' 28.6" with an uncertainty of 2.2 arcsec (radius, 90% confidence). This position is 50 arcsec from the Swift-BAT position. The light curve can be modelled with a power-law decay with a decay index of alpha=1.13 (+/-0.07). A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.0 (+/-0.4). The best-fitting absorption column is 1.7 (+0.6, -0.5) x 10^22 cm^-2, in excess of the Galactic value of 3.3 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 5.9 x 10^-11 (1.2 x 10^-10) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 1.7 (+0.6, -0.5) x 10^22 cm^-2 Galactic foreground: 3.3 x 10^21 cm^-2 Excess significance: 4.5 sigma Photon index: 2.0 (+/-0.4) The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/01267921.

At the counterpart positions reported by Swift XRT (GCN 38194) and Swift UVOT (GCN 38256), we detect no uncatalogued sources in H-band.
