Einstein Probe WXT detects potential GRB at RA 21.92°, Dec 66.60°
AI Summary
Einstein Probe's Wide-field X-ray Telescope triggered on a transient event on 2026-10-15 at 17:37:52 UTC with a signal-to-noise ratio of 6.0 in the 0.5-4 keV band. The source is localized to RA 21.92°, Dec 66.601° with a positional uncertainty of 0.05°. The net count rate of 0.014 counts/s is derived from a 20-minute accumulated image, which may underestimate the true flux for shorter-duration bursts. No follow-up observations or classification confirmations have been reported.
