              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
After Adlers Program we did a instrument block for the NA2 guide camera.
Mike Skrutskie then logged in to take some Jupiter/Io observations with TSPEC.  Very successful!!!
I then did some ARCTIC Fringe filter tests for Russet (start with image 4 in /ARCTIC_Fringe directory).  These were taken in LL mode (see below)
ARCTIC had a strange readout in quad mode.  the upper left quad was much fainter then the other three quads.  I sent a private email to Joe.  see atest.0039-41.  I did an init after exposure 39 and exp 41 was 5s instead of 60. I did find that after an arctic init the chip looks strange on the next exposure.  Another exposure after shows the "missing" quad.
I left ARCSAT in bypass mode so my observer could finish after SDSS closes their dome.
