               MOA 2007-BLG-197: sudden rise and fall


Dear Colleagues,

after observations by MOA and by PLANET with the Danish 1.54m at ESO LaSilla
and the SAAO 1.0m showed event MOA 2007-BLG-197 slowly rising above the
predicted ordinary light curve for about a week, recent PLANET data collected
with the Canopus 1.0m near Hobart (Tasmania) reveal a sudden rise and fall,
whose shape is compatible with a caustic exit, near the end and still in 
progress. First SAAO data from this night appear to agree with this.
 
Light curve and data are available on our webpages.

Event:           MOA 2007-BLG-197
RA (J2000):      18:07:04.729 
Dec (J2000):     -31:56:46.77 

The baseline I magnitude reported by the MOA team is 19.32.

PLANET observers:
Danish 1.54m:   Uffe Jorgensen, Tobias Hinse
SAAO 1.0m:	Ondrej Pecha, John Caldwell, John Menzies
Canopus 1.0m:   Stefan Dieters
