4. May 16th, Prelude to the Discovery
UT 10:35 OGLE-243 is binary, should we drop it? OGLE-270 too crowded?

UT 10:42
Yeah, I agree on OGLE-243, but OGLE-270 is interesting.

OGLE-270, OGLE-243 anomaly!

6. May 16th, Prelude to the Discovery
UT 17: “Fog is now causing 5 mags of extinction. Only Jupiter is visible now”
Grant
UT12: Fixing tracking;
More MOA-198, Fog is coming, look at OGLE-270?
Berto
UT 19:11, clouded out
Jennie
Did Jennie’s data, but can’t reduce the Auckland data (ap8). 
Subo
Yeah, let’s do OGLE-270!
UT 16: OGLE-270 is either peaking in 3 hrs at very high-mag or anomalous, priority override MOA-198
Andy

7. May 17th , by the noon (US) OGLE didn’t observe; Canopus clouded out
UT 16: Ask for 14 more CTIO points

10. Coordination Conclusions: I wish I don’t have to sleep
Have a wristwatch running UT
Maybe everyone should try Dave’s coffee while observing?
from David Moorhouse
to Subo Dong
Special observations require the right type of coffee I think we have some very noisy non-normalized data on the left hand side.
Isn’t this a planet???
