  Check out the paper by Udalski et al., available from
the astro-ph preprint server:

From the abstract:

    Photometric observations of three fields in the direction of
    the Galactic center (800 epochs per field) were collected on 32 nights
    during time interval of 45 days. Out of the total of 5 million stars
    monitored, about 52000 Galactic disk stars with photometry better than
    1.5% were analyzed for flat-bottomed eclipses with the depth smaller
    than 0.08 mag. 
    Altogether 46 stars with transiting low-luminosity objects were
    detected. For 42 of them multiple transits were observed, a total of 185,
    allowing orbital period determination. Transits in two objects:
    OGLE-TR-40 and OGLE-TR-10, with the radii ratio of about 0.14
    and estimate of the radius of the companion 1.0-1.5 R_Jup, resemble
    the well known planetary transit in HD 209458. 
    The transiting objects may be Jupiters, brown dwarfs, or M dwarfs.

 
  Very impressive!  The OGLE group looks at stars in the Large Magellanic
Cloud with a big telescope, so they are searching a very different 
portion of parameter space than the Mark IV would.  But it shows what
one can expect to find.  I recommend examining the JPG images of their
events you can find at
