It reached up to 14.0 mag in 2007 November. # I do not know how valuable this report is. Sorry if this is not important at all... http://www.aerith.net/pub/QSO_B0133+47.gif Special Notes We discovered a quasar QSO B0133+47 brightened up to 14 mag in 2007 November. It is recorded as 18-19 mag in the catalogs, so it is revealed to be an optically violently variable QSO. Taichi Kato commented that a quasar with such a large amplitude is rare. Well researched in the radio observations, however, little observed optically. Nobody has noticed that this quasar becomes so bright. It is about 7 billion light years from our planet, and the apparent brightness of 14 mag is extraordinary at this distance. In the DSS plates, it has been so faint as around 18 mag until 1992, but small outbursts have occurred twice in 1993 and 1995. However, it is much brighter than any past DSS plates in the MISAO Project CCD images on 2007 November 11. John Greaves pointed out that it is recorded bright as 14.3 mag and 15.0 mag in the UCAC2 and CMC14 catalogs. Both observations were in 2002. Reinder J. Bouma pointed out that it was recorded as 15.0 mag on 2002 Sept. 24 in the Skymorph archive. No records brighter than 18 mag have been found before 1992, and no records fainter than 17 mag have been found after 1995. This quasar may became very active in recent years. John Greaves reported that an infrared flaring was observed in 2008 November by I.N.A.O.E. (Instituto Nacional de Astrofi'sica, Optica y Electro'nica) in Mexico (ATel #1874). It turns to be so faint as 18-19 mag again in 2010. Esteban Reina Lorenz reported that it faded down to 19.18 mag in 2010 November. This is the faintest record in its history.
