              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had an amazing night tonight!  The sky was clear with sub arcsec seeing.  We tested the arctic diffuser and, aside from an issue up the diffuser not being able to retract while the instrument is inverted, everything worked well!
Eilat Glikman offered to give her time to Leslie Hebb, who has collaborators Suvrath Mahadeven and Gummi Stefanson being trained on site.
Tspec exhibited corrupted images and I will attempt power cycling it tomorrow.
