Wen-Jun Tan, Ce Cai，Shao-Lin Xiong report on behalf of the GECAM team:

GECAM-C was triggered by a short burst, GRB 240615A,  during the routine ground search at 2024-06-15T17:51:45.100 UTC (T0), which was also detected by Fermi/GBM (GCN #36671), Swift/BAT-GUANO arcminute localization(GCN #36672) and Konus-Wind (GCN #36677) . 

According to the GECAM-C light curve, this burst shows one single pulse with a total duration of ~0.1 sec.

We note that these results are very preliminary. Refined analysis will be reported later.

Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission originally consists of two micro-satellites (GECAM-A and GECAM-B) launched in Dec. 2020. As the third member of GECAM constellation, GECAM-C was launched onboard SATech-01 experimental satellite in July 2022. GECAM mission is funded by the Chinese Academy of Sciences (CAS).
