The OGLE team informs about a microlensing event in progress -
OGLE-1998-BUL-18 (17:54:21.79, -29:53:24.0, J2000)
which is presently about 2 days before maximum.
It is relatively bright star (I0=15.5), rising rapidly.
Preliminary microlensing fit to the light curve predicts
large maximum magnification to be reached on
JD=2450971.831 (1998-06-07.33 UT)
Follow-up observations, both photometric and
spectroscopic, are strongly encouraged. Finding chart, coordinates
