PSL Weekly FAMIS Task (3920 and 8849)
High power oscillator diode box current adjustment(s) [FAMIS 8449]

With the ISS off, the diode box currents were adjusted.  A screen dump of the laser main screen is attached.

Diode Box [#] Old [A] New [A]
1 52.3 53.0
2 54.5 54.8
3 54.5 54.8
4 54.5 54.8
Another largish increase, just like last week. Not surprising really given that the diodes are near their end of life. The power, with the ISS on, went from ~153 W to ~155 W. This completes FAMIS task 8449 Power watchdog reset [FAMIS 3920] Both the front end and oscillator power watchdogs were reset at 18:24 UTC (10:24 local). This completes FAMIS task 3920.
