1 Schmeer, Patrick This object was observed above its usual brightness only on 2021 February 26 and 27, and possibly March 2 (vsnet-alert 25544). Extremely long flare or fast microlensing event? BY variations (~0.2 mag.) at minimum. Gaia EDR3 parallax 18.686 ± 0.028 mas (distance 53.46 ± 0.08 pc). ASAS-SN magnitudes contaminated by nearby stars. Range has been corrected.
