I don't know the switch-on time but here is a series of
10 minute measurements in 1.66 mHz bandwidth,

Time is start time of 10 minute measurement.  Looks like it
came on within +/- 5 mins of 00:30 UT - but was there some
tune-up or something before then, say from 00:10 onwards?
Hard to say from here.  Background noise starts to rise
rapidly from about 23:30 but this is distinguishable by
its random phase.   Phase seems to go steady from 00:10
onwards.
