Observer: Juan Espinoza
Observed for most of the night from 0230 to 0830 UTC.
Conditions were Non-Photometric most of the night.
Problems were encountered, see the summary for details.

Seeing and Weather:
   Beg: Seeing 1.6 arcsec, Patchy Clouds, Winds Light & Variable
   Mid: Seeing 1.8 arcsec, Cirrus, Winds Calm
   End: Seeing 1.6 arcsec, Cirrus, Winds Calm

Observing Summary:

Late start because of clouds - 0230 UT (10:30pm)

Because of this I was only able to get a short amount of data for
Portugal (no SKY, second round of S279, and no normacore)

On the first target (s279) the observations were not in order (j instead of h first)
I was able to get observe HD193727 and HD221624.
(I am not sure if this is worth doing)(I would appreciate it if Portugal 
would let us know if the whole Portugal program is worth doing
if the complete program won't be finished).

Not all OSU targets were observed due to the lack of time.

Aql's differential magnitude in R band = 2.45
