A. Udalski and M. Szymanski, on behalf of the OGLE collaboration:
The Early Warning System (EWS) designed for detection of
microlensing events in progress has been implemented for the
second phase of the Optical Gravitational Lensing Experiment -
OGLE-2. Information about detected events in progress is
available on WWW
page and
Anonymous FTP.
Astronomers interested in e-mail notification,
are requested to send an e-mail to ogle-ews@sirius.astrouw.edu.pl.
Short notes will also be posted at The Astronomer's Telegram page.
Each night about 25 million stars are monitored in the Galactic
bulge with the 1.3-m Warsaw telescope at Las Campanas
Observatory, Chile. Also large parts of the LMC and SMC are
regularly observed. In the 1998 bulge season (Mar-Oct) 15
microlensing event candidates has already been detected. 5 of
them are still in progress. The expected detection rate is about
50 microlensing events per observing season.
