                ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: G.Saurage
 We had a sucker hole aright after sunset that we jumped on. We managed to
 stay open an hour before the threat was back. Opened 22:50 again during
 another hole, closed again at 00:20.
 2nd half Observing Specialist: R.McMillan
 Second half had a variety of fast-moving storms with rain, hail and
 lightning, plus high humidity and gusty winds.  There was a while
 when I thought we might have a hole open up, so I spent a lot of
 time watching weather closely.  Fortunately I didn't open, as the
 apparent hole turned into more rain with very little warning.
