Observing Summary:

Hello -

Non-photom program completed (almost). -- At the beginning, although clear
skies above, was very hazy and with a lot of clouds to the north wich
eventually moved in at around 0530 UT.

Again.  Lots of problems observing Portugal targets; sn1999ao... no problems.
nb-225, however, was observed once for 1200 sec. only to get an extremely
elongated image due to light and variable winds but strong enough to not let
me keep the telescope still (even with one great guiding star). I tried going
back to it but it was no use, the telescope kept on oscillating.  The rest of
the other Portugal targets were observed with similar problems but
accomplished anyhow.

The rest of the program accomplished accordingly and I obtained CCD sky flats
in both binnins - 2x2 & 1x1.

Differential magnitude for Aql: 3.44
Magnitude of XTE in V band: 18.2

cheers and see you next week
