Everything is looking normal. ISS diff power is a bit low but has been jumping up to ~2.5% every once in a while, and AMP1 output power is also a little low.


Laser Status:
    NPRO output power is 1.827W (nominal ~2W)
    AMP1 output power is 64.37W (nominal ~70W)
    AMP2 output power is 137.4W (nominal 135-140W)
    NPRO watchdog is GREEN
    AMP1 watchdog is GREEN
    AMP2 watchdog is GREEN
