General information
COLIBRÍ observed the field of GRB 260430A / EP260430a and reports no optical counterpart in stacked imaging at the referenced WXT position. The observations were taken 2.55–6.29 hours after the trigger with simultaneous r and z exposures.
Wavelength coverage
- Optical: 3σ upper limits in stacked imaging, r > 22.38 and z > 21.78 (AB; not corrected for Galactic extinction).
- X-ray: only the WXT source position is referenced; no X-ray measurements are reported here.
No observations are mentioned here for UV, IR, radio, gamma-ray, gravitational waves, or neutrinos.
