TL;DR: In this paper, an extremely bright gamma-ray burst (GRB) 160625B was observed in both gamma and optical wavelengths, with three isolated episodes separated by long quiescent intervals, with the durations of each sub-burst being approximately 0.8, 35, and 212 seconds.

TL;DR: In this paper, the authors reported an extraordinarily bright gamma-ray burst (GRB) 160625B, simultaneously observed in gamma-rays and optical wavelengths, whose prompt emission consists of three isolated episodes separated by long quiescent intervals, with the durations of each "sub-burst" being $ 0.8 s, 35 s, and 212 s, respectively.

TL;DR: The Mini-MegaTortora (MMT-9) as mentioned in this paper is a nine-channel wide-field optical sky monitoring system with subsecond temporal resolution, which can observe sky areas as large as 900 deg2, perform photometry in three filters close to Johnson BV R system and polarimetry of selected objects or areas with 100-300 deg2 sizes.
