Details on Acronym:   EWS
  
EWS (Early Warning System)= OGLE
Write:<<OGLE YYYY-AAA-NNN>>
<<OGLE YYYY-AAA-NNNN>>
Object:Microlensing Event  (SIMBAD class: LensingEv = (Micro)Lensing Event)
Note:OGLE microlensing events, first named by the authors as OGLE NNa events in Galactic Bulge.
Starting 1998, the year has been included in the format: 'YYYY-BUL-NNN' and the objects were at first designated 'EWS'.
In other galaxies, events have the same format. For example, 1999-CAR-1 microlensing event observed in the Carina galaxy, or 2005-SMC-001 in the SMC.
