At 8:00 received Verbal of an injection ("Transient injections detected").  Could noticeably see elevated PCALX spectrum (pink circle trace) on the running DARM measurement in the front of the Control Room.  Attached is a screenshot of the INJ_TRANS guardian node windows, other CAL windows and running DARM measurement as well. 

With regards to the Guardian, this was controlled automatically (i.e. no operator intervention).  INJ_TRAN went to a INJECT_STOCHASTIC_ACTIVE state when it was running and then returned to the normal WAIT_FOR_NEXT_INJECT state when injection was complete.

8:00-8:13 Period when injection was run.  H1 range took a notable drop to about 105Mpc during this time.
