[vsnet-j 2717] V4745 Sgr: prediscovery data


　すごい情報が入りました。ASAS survey が本格稼動していて、V4745 Sgr の増光
　フェーズを捉えていたようです。データは自動公開されるらしいので、その気に
　なればいろいろ探せるのかも知れません（新天体探しまで可能なのかどうかは
　わかりませんが）。

＃これらのサーベイデータをもとに何か発見した場合の credit とかはどうなる
＃んでしょうね？

Dear Taichi Kato,

ASAS has measured the following light curve of V4745 Sgr:

object           HJD      YYYYMMDD(UT)     mag   inst

SGRV4745     2737.85456   20030408.35456 <14.0V ASAS3V
SGRV4745     2739.86553   20030410.36553 10.63V ASAS3V
SGRV4745     2741.83844   20030412.33844  8.37V ASAS3V
SGRV4745     2743.83514   20030414.33514  8.02V ASAS3V
SGRV4745     2744.85345   20030415.35345  7.80V ASAS3V
SGRV4745     2747.86327   20030418.36327  7.41V ASAS3V
SGRV4745     2755.78626   20030426.28626  9.26V ASAS3V
SGRV4745     2757.79449   20030428.29449  9.32V ASAS3V
SGRV4745     2759.85935   20030430.35935  9.44V ASAS3V

Please note, that any photometric measurement of the ASAS3V system
is available over the internet within 5 minutes after observation.
It takes about 1.5-2 nights to cover the whole sky, so most of the
recent measurements of any object are only 0-2 days old.

One can access current (and archive) photometry of any object directly from
http://vsnet.astrouw.edu.pl/cgi-asas/asas_lc/ID
where ID has format HHMMSS-DDNN.N 
	HHMMSS - right ascension, 
	[+or-]DDNN.N - declination (DD -degrees, NN.N - minutes)
e.g. 
SGRV4745 http://vsnet.astrouw.edu.pl/cgi-asas/asas_lc/184002-3326.9

Regards,
Grzegorz Pojmanski, ASAS
