Hello,
ASASSN-25ao, an outbursting blue object was observed at CBA-KKO on 3 and 4 Feb 2026.
The object faded from an average of 15.85 to 16.16 CR (unfiltered magnitudes) over that period. The light curves showed a modulation hinting at a main period around 0.12d and a strong secondary period of 0.030d +/- 0.0005d, derived from GLS and PDM methods in Peranso.
Further observations are planned for Friday 7 Feb, when skies will be clear again.
