Observing Specialist: D.DeColibus
Previously reported TSpec pattern noise showed up in the instrument checkout darks. (tpsec_dark.0006.fits). Pattern is slightly misaligned from rows and columns at an angle of about 2 degrees.
Sky was clear all of first half, with some thin high clouds beginning around midnight and persisting until around 04:00.
No problems tonight.
