All of a sudden, starlight is not coming into the STT. It is visible in the acq camera. Track spiral search took a long while to recover.

Ever since this incident, the STT had a hard time trying to keep the star in the STT box. STT pupil is moving in and out of the box. No fringes obtained ever since.

Fringes found at -1180um earlier.
