Itagaki, Yamagata, Japan, reports (via H. Yamaoka, Kyushu University) that this possible supernova (cf. CBET 2569) was fainter than mag 19.0 in his image taken on Dec. 1.608 UT, which indicates that this is a recent outburst. Corrigendum. On CBET 2569, the website URL for the discovery image should read: http://www.jacopobaldi.it/dati/psn%20in%20NGC1954.jpg.
