AI Summary
CHIME/FRB pipeline identified a subsequent fast radio burst (FRB) on 2026-07-10 at 19:59:42.844 UTC with high association probability (0.98) to known source 1163334440, indicating a likely repeating FRB system. The burst exhibits a dispersion measure of 173.88 pc/cm³ with SNR of 17.03, localized to RA 291.39°, Dec 85.90° with ~6 arcsecond positional uncertainty. Observations span 400-800 MHz with dual polarization, confirming astrophysical origin from a high-latitude source near the celestial pole.
