Dear Colleagues,

Combined fits to PLANET collaboration data and public OGLE   
data for the OGLE-detected microlensing event OGLE 99-BUL-035 
indicate that this event is a very high amplification 
event that may have peaked near JD = 2451392.6, that is, 
about 15 hours before the date of this message.  

Event:           OB-99-035      (OGLE 99-BUL-035)
RA  (J2000):     17:49:01.66 
Dec (J2000):    -30:15:40.4

Baseline I magnitude reported by OGLE team is 18.89. 
The event appears to be exceedingly faint in the V band.
Approximate current magnification is about 34.                     

This event should be monitored closely to measure source 
resolution effects near the peak, which may be used to 
determine the relative proper motion of the lens.  Such 
high amplification events are also particularly sensitive 
to the presence of stellar and planetary companions.
