(chart and light curves)
VSNET real-time light curve system is now available through WWW. This system automatically reflects the observations (to vsnet-obs) reported in the VSNET-recommended format (see the Web pages for details).
The system is still in test operation. As initial targets, we have chosen SS Cyg, Nova Cas 1995, AM Her, V1159 Ori and omicron Cet (Mira). Some of them have been chosen to support the current schedules of satellite observations. If you are observaing these stars, we would be very glad if you can report the stars in question in the prescribed format by VSNET. To participate in this real-time light curve project, it is enough if you can append a few to several lines of observations in VSNET format, to your regular observations. We hope this might not be so time-consuming.
In you have recommendations to the real-time light curves, please feel free to send a mail to vsnet-adm@kusastro.kyoto-u.ac.jp.
