              ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Clear skies overhead but radar returns in neighboring counties most of the night.
Variable seeing. Near morning twilight, clouds and radar returns approching.
Pointing has been off on NA1 in NE portion of sky last two nights echelle has been
on (did not do an echpoint because running out of time on sky). With a a little
cloud + filter, ecam looks like flat field with light on the right side of field,
see 851-852.fits.
ecam locked up, non responsive with blank field (see file 857) giving this error:
10:44:52 APO.gabrelle.ecam 9 ecamera f text="could not read new image file: [Errno
2] No such file or directory: '/export/images/forTron/guider/gimg0206.fits'"
10:44:52 APO.gabrelle 865 ecam f text="\"could not read new image file: [Errno 2] No
such file or directory: '/export/images/forTron/guider/gimg0206.fits'\""
power cycled ecam and recovered. We continued exposing the whole time so no time was
lost.
