General information
SVOM/VT performed ToO observations of the Einstein Probe trigger field and reports no uncatalogued optical source within the EP-FXT and EP-WXT error regions at ~20 hours post-trigger.
Wavelength coverage
- Optical (400–650 nm; VT_B): 3σ upper limit > 23.5 mag at mid-time 21.53 h (57×50 s).
- Optical (650–1000 nm; VT_R): 3σ upper limit > 23.3 mag at mid-time 21.53 h (57×50 s).
No observations are mentioned in gamma-ray, X-ray (beyond localization), UV, IR, radio, mm, or neutrinos.
