Yoshida, Japan, writes that the quasar 0133+476 (also known as DA 55; cf. Veron-Cetty and Veron 2001, "A Catalogue of Quasars and Active Nuclei (10th edition)", see: http://www.obs-hp.fr/www/catalogues/veron2_10/table1A_v10.dat; RA 01h 36m 58.6s DEC+47 51' 29" (2000) has been found to be notably bright, as indicated by the following CCD magnitudes provided by members of Yoshida's MISAO project (all using an SBIG ST-8 camera): 2000 Dec. 1.47 UT, 16.2 (N. Ohkura, 500-mm camera lens); 2001 Dec. 11.46, 15.5 (Ohkura); 2002 Jan. 2.40, 16.6 (Ohkura); 2007 Sept. 12.81, 15.4 (Y. Nakashima, 7.6-cm f/6.6 refractor); 2007 Oct. 6.75, 15.3 (N. Ohkura and Y.Nakashima, 7.6-cm f/6.6 refractor); 2007 Nov. 11.63, 14.1 (Nakashima); Dec. 3.52, 14.9 (Nakashima) The USNO-A2.0 catalogue lists this quasar at red mag 18.3 and blue mag 18.5.

S. Blondin et al. add that a spectrum of Feb. 8.43 UT by Calkins, shows it to be a type-II-plateau supernova, 3-4 weeks past explosion.
