Subject: Long term SLED test - Day 1 

 The measurement from the on-board PD of the Superlum SLED seems to be falling. This effect started around 5PM last night which is right about the time we moved the position of the PD that the SLED is illuminating on the optical table (via optical fiber).

Curiously, the current set point and delivered current to the SLED are dropping as well.
