MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) was pointed to the Integral GRB241109.89 (trigger No 10977,18h 41m 18.94s , -04d 57m 00.0s, R=0.0492) errorbox 10450 sec after notice time and 10459 sec after trigger time at 2024-11-10 00:19:23 UT, with upper limit up to 17.2 mag. Observations started at twilight. The observations began at zenith distance = 67 deg. The sun altitude is -15.1 deg.
The galactic latitude b = -1 deg., longitude l = 28 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2663731
We obtain a following upper limits.
Tmid-T0 | Site |Filt.| Expt. | Limit| Comment _________|_____________________|_____|_______|______|________
10464 | MASTER-OAFA | C | 10 | 16.8 | 10508 | MASTER-OAFA | C | 15 | 16.9 | 10558 | MASTER-OAFA | C | 30 | 17.0 | 10603 | MASTER-OAFA | C | 30 | 17.0 | 10650 | MASTER-OAFA | C | 30 | 17.0 | 10685 | MASTER-OAFA | C | 30 | 17.0 | 10721 | MASTER-OAFA | C | 30 | 17.0 | 10780 | MASTER-OAFA | C | 60 | 17.2 | 10846 | MASTER-OAFA | C | 60 | 17.2 | Filter C is a clear (unfiltred) band.
The observation and reduction will continue. The message may be cited.
