General information
Swift triggered on GRB 260118.48 (trigger 1442056) at a position near RA=11:20:55.22, Dec=−61:54:33.5 with a reported error radius of about 0.05°. MASTER-SAAO observed the field ~3.25×10^4 s after the trigger and reported only optical upper limits.
Wavelength coverage
- Gamma-rays: Swift trigger reported.
- Optical: MASTER-SAAO clear-band (C) imaging gives upper limits of ~18.0–18.3 mag at ~3.245×10^4 s post-trigger.
No observations were mentioned for X-ray, UV, IR, or radio.

Redshift
What’s special vs typical
- The field lies at very low Galactic latitude (b ≈ −1°), which can make optical counterpart identification harder due to extinction and crowding.
