This study presents a comprehensive analysis of early emissions of short optical transients, leveraging data from the GLOBAL MASTER MSU Network’s robotic telescopes. These transients, often accompanying cosmic phenomena like gamma-ray bursts, orphan bursts, gravitational wave bursts, high-energy neutrino events, and supernova precursors, pose significant challenges due to their brief nature and unpredictable timings. The core of the research focuses on the transient phenomena’s detection and characterization, utilizing the unique capabilities of the MASTER network’s telescopes. These include rapid targeting, wide-field imaging in multiple polarizations, and real-time data processing. Emphasis is placed on the network’s ability to capture and study these phenomena, contributing to the understanding of their origins and mechanisms. Several targets are discussed: the detected GRB 210731A optical counterpart,the BZQJ0526-4830 optical flare, the 2022 outburst of the dwarf nova AT2019axa 2022, the newly discovered Nova MASTER OT J010603.18-744715.8 in the SMC, the IIb Supernova MASTER OT J091344.71762842.5 / SN2017gkk and the SWIFT J0840.7-3516 X-ray transient. © 2025: Instituto de Astronomía, Universidad Nacional Autónoma de México.
