Description

On 26 February 2026 at 10:38:18.84 UT, Fermi-LAT triggered on high-energy emission from GRB 260226A. This event exceeded a very high energy threshold, making it only the second GRB to do so since GRB 090510. Following this alert, we conducted follow-up observations of this source. Here, we present the WCDA observations from both triggered and triggerless data, along with some preliminary results.
