もう９月の半ばだが、９月に入って快晴の夜は無い。３日ほど撮影を試みた夜があったが、曇りで中断になっている。
８月は大変暑かったが、晴れた日も多かった。倉敷に帰省していたこともあって、撮影は思うように進まなかった。
そんな中、世界時９月８日に、へびつかい座新星が発見された。同夜に撮影していたが写っておらず、最初、新星出現は誤報と思っていたが、翌９日に撮影した画像にはしっかり写っていた。
https://blogs.yahoo.co.jp/novaaql1993/38029536.html
他に、新星関連の発見の情報は無かった。UGEMを使った変光星観測も観測星が定まらず、まったく進捗なくリストができていない。
その他、最近思うのは、ASAS-SNやKWS他、自動サーベイ、全天撮影がなされ、CVなどのCCDや写真による観測は、それほど必要性が無くなったのではないだろうか？ それより、眼視でいつも眺めていた視野に、忘れた頃にピカッと光る星を自分の目で捕らえる、そんな醍醐味を味わえるのはアマチュアしかいない。

へびつかい座新星 No3
Brazilian Transient Search (BraTS)のC. Jacquesさん, J. Barrosさん, E. Pimentelさん, P. Holvorcemさんらのグループは、8月8.96日(世界時; 以下同様)に口径28cmの望遠鏡とCCDカメラを用いて撮影した画像から11.1等の新星を発見。
2018 08 9.112
Discovered by C. Jacques, J. Barros, E. Pimentel, P. Holvorcem, on behalf of the Brazilian Transient Search - BraTS - at SONEAR Observatary, Oliveira, Brazil with three frames with 10 seconds exposure using an astrograph 11"f/2.2 + CCD camera under limiting mag = 16.5. Nothing is visible at this location on the previous frame (limit mag = 16.0) taken 2018 July. 8.991 UT.

TCP J19544251+1722281 was found by Robert Fidrich, Budapest, Hungary on DSLR images made using 4x60s DSLR images made Canon EOS 1000D camera with 180mm focus telephoto lens. The star was 12.0V on 31.9451 July and 11.66V on 3,9886 Aug. and 10.7V on 08.9381 Aug. VSX lists an SR variable ASASSN-V J195442.95+172212.6 with a range between 12.16-12.84V with 418 days period. ASAS-SN data show a sudden rise from 12.35C on 05.49 August to 11.46V on 06.3317 Aug -- a strange fast brightening for an SR variable with 418 days period. Maybe a symbiotic variable in outburst?
