【Overview】
この二ヶ月間も日本の新星ハンターがそろい踏みといった感じでTOCPに掲載されたが、TCP J05390410+4748030 や TCP J18325790-1642211は、ASAS-SNでも捕らえられている。私もTCP J18325790-1642211のマイクロレンズ現象は同日撮影したので画像を再確認した結果、かろうじて写っていた。ASASS-Nは他にも明るいCVをたくさん発見した。14等まで明るくなったのは10個もあった。
その他、VSXに未登録の新変光星に気づいた。詳細は下段に記すが、今回もスイスにお住まいの笠井さんのご努力でVSXに登録された星があり、お忙しい中の作業で、頭が下がるばかり。

Yuji Nakamura, Kameyama, Mie, Japan, reports his discovery of this TCP (mag 11.3) in
Aur on a CCD frame taken on 2019 Mar 14.4227 UT (limiting mag 13.0) using a 135mm F4.0 lens. The object was not shown on a frame taken on 2019 Mar 09.4284 UT (limiting mag 13.0). There is a 19.2 mag star USNO-A2.0 1350-06029095 on this position.

新変光星
①YmoV07 18 14 11.88 -30 13 31.8
2015年にも増光に気がついた、VSXに未登録の星（M型？）。近くに MACHO123.24768.1053 (RRAB) があるが、 OGEL BLG525.4 94932 と同定され別物だろう。
変光の様子は以下のASAS-SNで確認できる。

笠井さんによる周期解析などによってVSXに登録された。ありがとうございます。
変光の様子は以下のASAS-SNで確認できる
③YmoV16 191601.78-071413.5 = NSVS13995739
もともと2014年に増光に気づき、昨年も位置が間違っていると指摘していた。しかし、位置や変光範囲などが明らかに異なるので今回新変光星と報告したが、結果的に NSVS13995739 の位置、要素が間違っていたということになった。一応、他の名称としてYmoV15が追記された。

④YmoV15 16 51 09.74 -33 31 02.9
VSXに未登録の変光星（ミラ型？）で明るい。まだ未登録なのが不思議なくらい。
ASAS-3のデータから P=200d前後、変光範囲は、11.8-<17V のようだ。
ライトカーブは、ASASSN-S/Pの以下で確認できる。まだ未登録の星。
位置は、USNO-A2.0カタログ0525-24255836 14.4B 14.2R から引用。
