AT 2026eva (Orion)
AT 2026eva (Type: CV?) discovered 2026-03-03.154 UT by GEOTS
Alias: GEOTS-Balaji-2026-002
Discovery Magnitude 16.6 (Clear- Filter)
vs Prior Non-Detection Limiting Magnitude 18 (Clear- Filter)
Discovered in Ori using 14" f/2.0 Astrograph at Golden Ears Observatory (MPC code U55).
We report a variable star candidate not currently archived in the VSX database.
Analysis of ASAS-SN (All-Sky Automated Survey for SuperNovae) light curves
reveals a brightness fluctuation exceeding 1.0 magnitude, suggesting a potential long-period
variable or high-amplitude eclipsing system.
