Objects Session Notes
(2) Pallas - Minor Planet 220P/McNaught - Comet C/2022 N2 (PANSTARRS) - Comet Nova Per 2020 - Nova (N Per 2020, PGIR20fbf, TCP J04291888+4354233, TCP J04291884+4354232) AT 2026yvy - Type Nova? Transient (non-detection) - UGC 4424 attempt failed (due to bad guiding) Variable Stars (photometric monitoring) - RZ LMi Nearby Stars (astrometric monitoring) - Gliese 65 (UV Cet)
