Dear CBAers,

This would be an interesting event to follow in photometry.  An I filter
would be ideal, but unfiltered is OK if you don't have the filters.  It's
likely to be a quite crowded field - I didn't say it would be easy!

Subject: Extreme Microlensing Event

Dear Suvi,

        Tonight, there is a very rare microlensing: an
extremely high magnification event of an intrinsically
bright star.  I expect that it will be I=11 over MDM
tonight.  This presents a rare chance to get a spectrum
of a bulge star when it is highly magnified.  Also,
if the event undergoes a caustic crossing, spectra
can effectively spatially resolve the source.  If you
are interested in getting a spectrum of this source,
please let me know.  The source is called OGLE-2004-BLG-254.
Its J2000 coordinates are:

17:56:36.20  -32:33:01.8
