Michael,

Well, I miss on two counts.  I had previously been looking at the 
equator.  But only down to about -1.  Possibly I get to -1:37 but I doubt 
it.  I will check the data for pre-event data.  In case you did not notice, 
there was a (near) full moon last night so I was looking at +70.  Even 
there I got mostly saturated frames.
