MisV1436 = QSO B0133+47 の変光（撮影：大倉信雄さん、中島洋一郎さん）
視野：約12分角
このクエーサーの変光は、MISAOプロジェクトの新星探しの中で、吉田誠一（MISAOプロジェクト）が発見しました。中島洋一郎氏（岡山県）が2007年11月11日に撮影したノーフィルターCCD画像から、新星候補の1つとして、PIXYシステム2によって検出されました。吉田は、中島氏と大倉信雄氏（岡山県）が撮影した、2000年から2007年までのCCD画像を調べ、この天体が変光していることを確かめました。
このクエーサーのデータは、下記の通りです。

これらのカタログには、18〜19等のとても暗い天体と記されています。しかし、MISAOプロジェクトの観測では、2007年11月には14等まで明るくなっていました。
クエーサーは、たいへん遠くにある活動銀河の核です。たいていは電波で観測されていますが、目で見られるものもあります。電波の強さが変化することが知られていますが、目で見た明るさも変化します。しかし、京都大学の加藤太一氏によれば、これほど大きく明るさを変えるものは珍しいとのことです。
(2008年2月14日追記)
綾仁一哉氏（美星天文台）によれば、クエーサーには電波の強いものと弱いものがあり、電波の強いクエーサーは少数派であるそうです。
この天体は、クエーサーの中でも特に明るさの変化が激しい、「可視激変光クエーサー」と呼ばれるブレーザーのようです。綾仁一哉氏（美星天文台）によれば、これは、クエーサーの中でもかなりの少数派だそうです。このクエーサーは70億光年の彼方にありますが、この距離で14等というのは、凄まじい明るさです。
これまでの調査では、このクエーサーは電波では良く観測されており、電波の強度が変化することも分かっていましたが、可視光はあまり観測されていなかったようです。これほど明るくなることも、これまでは知られていませんでした。
そこで、MISAOプロジェクトでは、この天体をMISAOプロジェクトの1436番目の新しい変光星として、MisV1436 という符号を付けました。

1992年まではずっと18等前後の、たいへん暗い状態が続いていました。ですが、1993年と1995年の二度、小規模なバーストが起きていたようです。
しかしながら、MISAOプロジェクトの2007年11月11日の画像では、このクエーサーは、DSSのどの乾板よりも、はるかに明るく写っていました(*4)。MISAOプロジェクトでは、このクエーサーの、史上最も明るい姿を捉えられたことになります。
John Greaves氏は、UCAC2 と CMC14 という2つのカタログを調査して、このクエーサーが、UCAC2カタログに14.3等と記載されていることを指摘しています。これは、このクエーサーが2002年7月半ば頃にも、かなり明るかったことを示しています。CMC14カタログにも15.0等と記載されており、2002年後半にも明るかったことを示しています。CMC14カタログによれば、光度の標準偏差が0.7等以上もありますが、このクエーサーの変光の影響かもしれません。
また、Reinder J. Bouma氏は、Skymorphのアーカイブを調査し、このクエーサーが2002年9月24日に、15.0等の明るさで撮影されていることを見つけました。
このクエーサーは、1992年以前の画像では、18等より明るい記録が見つかっていません。また、1995年以降では、つねに17等より明るく記録されています。このクエーサーは、最近になってかなり活発になってきたのかもしれません。
綾仁氏によれば、このクエーサーは偏光率が高く、光度変化の大きいタイプの特徴を持つとのことです。下記の文献で、スペクトルに幅の広い輝線が観測されていることから、ブレーザーの中でも、BL Lac天体ではなく、「可視激変光クエーサー」に分類されるとのことです。
http://ads.nao.ac.jp//full/1996ApJS..107..541L/0000564.000.html
Greaves氏によれば、NASA/IPAC Extragalactic Database にて、このクエーサーの電波観測を参照することができます。この天体の相対論的な電波のジェットが電波強度の変化に寄与している様子が見られるとのことです。

2008年〜2009年のシーズンは、12月と3月に、二度のアウトバーストを起こし、12月18日には14.5等、3月18日には14.8等に達しました。
12月下旬から3月上旬までは、16等前後の明るさで推移しました。
1月7日には、Miguel Rodriguez Marco氏によって、突発的な減光も観測されました。
(2011年11月12日追記)
2010年の夏から冬にかけては、18〜19等と極めて暗い状態が続きました。
Esteban Reina Lorenz氏の観測では、2010年11月20日に19.18等と、史上もっとも暗い光度を記録しました。
しかし、2011年に入ると増光に転じ、2月には16等台半ばまで復光しました。
2007年から2011年にかけて、長期的には減光が続いています。
