AT 2026kqj  - CV Type Transient

AT 2026kqj (Cygnus)
AT 2026kqj (Type: CV) discovered 2026-04-24.344 UT by GEOTS
Alias: GEOTS-Balaji-2026-006
Discovery Magnitude 16.2 (Clear Filter)
vs Prior Non-Detection Limiting Magnitude 18 (Clear Filter)
Discovered in Cyg using 14" f/2.0 Astrograph at Golden Ears Observatory (MPC code U55).
Group reports the discovery of a variable source located in Cygnus. The source has undergone a
significant flux increase, brightening by approximately 2 magnitudes since its last recorded
observation on April 17, 2026. Notably, the object is an orange star, suggesting a late-type
stellar classification. A search of the International Variable Star Index (VSX), Gaia DR3, and
the ASAS-SN Sky Patrol database yields no prior record of known variability or cataloged
transient activity at this position.
