We detected the optical afterglow of GRB 250430A, about 4.75 hours after the burst. On 30 April 2025 at 17:21:31 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 250430A (trigger=1308754). This...
We detected the optical afterglow of GRB 250419A, about 37 hours after the burst. On 19 April 2025 at 02:29:32 UT, SVOM/ECLAIRs triggered and located GRB 250419A. This detection was reported via the Nasa’s...
We detected the optical afterglow of GRB 241030A, about 37 hours after the burst. On 30 Oct. 2024, at 05:48:03 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 241030A (trigger=1263718). This...
On 13 April 2015, at 13:54:58 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 150413A. This detection was reported via the Nasa’s GCN 17688 Circular. 132 seconds after the burst, the MASTER II robotic telescope located...
On the night of 9 May 2014, we tried to observe the optical counterpart of GRB 140508A, reported earlier the previous day. These afterglows fade quite quickly, but we tried anyway. Several 300 seconds...
On the night of 6 Feb. 2014, we tried to observe the optical counterpart of GRB 140206A, reported earlier that day. These afterglows fade quite quickly, but we tried anyway. Several 300 seconds unfiltered...
The night between 31 Aug and 1 Sept. was particularly fruitful for the Virtual Telescope Project. While spectroscopy and photometry of several targets were ongoing, we tried to observe the optical counterpart of GRB...
The sky is always ready to give a show at any moment. On 6 June 2013, at 21:26 UT,while doing other scientific activities at Virtual Telescope, we received an alert reporting that a GRB...
