Chen-Wei Wang, Shao-Lin Xiong, Shi-Jie Zheng and Yan-Ting Zhang report on behalf of the Insight-HXMT team:

At 2024-11-14T11:05:03 (T0), Insight-HXMT/HE detected a long burst, GRB 241114B.

The Insight-HXMT/HE light curve mainly consists of three
episodes with a T90 of 25.0 +0.3/-0.5 s. 
The 1s peak rate, measured from T0+30.5 s, is 7255 cnts/sec. 
The total counts from this burst is 33848 counts.

All measurements above are made with the CsI detectors operating in the regular mode with the energy range of about 80-800 keV (deposited energy). Only gamma-rays with energy greater than about 200 keV can penetrate the spacecraft and leave signals in the CsI detectors installed inside of the telescope. 

Insight-HXMT is the first Chinese space X-ray telescope, which was 
funded jointly by the China National Space Administration (CNSA) and 
the Chinese Academy of Sciences (CAS).
