EWS    (Early Warning System)= OGLE 
 Write:<<EWS  YYYY-AAA-NNN>>  

        <<EWS  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.
    Since 1998, the year is included in the format 'YYYY-BUL-NNN'    and the objects are designated 'EWS'.
    In other galaxies, events have the same format:    ex.: 1999-CAR-1 microlensing event observed in the Carina galaxy,    2005-SMC-001 in The SMC.
    See the OGLE-IV Early Warning System webpage:    http://ogle.astrouw.edu.pl/~ogle/ogle4/ews/ews.html 
    Only first refs with EWS objects are cited.
