SST Observing Report: 09-July-2004

Summary: On our last day, the best day yet. The wind was over 10
m/sec all day but was unfortunately a little too far east to give
completely excellent seeing. But we observed all day and have many
many excellent frames that will be MFBD-restored to the highest
resolution. No movies longer than probably 10 minutes though - the
seeing was always highly variable due to gusty turbulence out of
the caldera.

Observed AR 642 in the morning until 1230 UT at which point we
switched to the new spots emerging at about S7 W1 - very close to
disk center. We also did 15 minutes of quiet Sun at Disk center at
1540 in concert with TRACE. We stored every frame of this target
in order to try and get a high cadence movie. Seeing wasn't good
enough though to give a cadence higher than about 30 seconds.


Observers:  Tom Berger, Mats Lofdahl, Goran Scharmer.

Targets:    AR 642 at S8.4 E45.3
            New AR at S7.3 W1.2
            QC at disk center for 15 minutes.

Weather:    morning conditions T = 12C, h = 5%, W = 12.3 m/s
            from 68 deg.

Seeing:     good/very good from 8 to 1700 UT! No long movies, but
many many excellent frames scattered throughout the day.

Optical setup:   Cameras 1,2, & 3 are synchronized with the Oslo
external shutter.
