I've been watching this with interest throughout the day. Is this the first NLC detected so far for 2008, and, if so, for how long has the data been collected? I can't seem to find any relevant archives on the site.

as far as I know they started their campaign (online!) on 2008-05-15. I watched the site the time before and there was always the hint to "come back next summer campaign". The first part of measurement images ("profiles") were shown online on 2008-05-15 and the complete results ("profiles" + "image") on 2008-05-16.
There >can< be a >weak< hint for a short detection on 2008-06-04 at approx 19:30 pm but the results from today are evident.
NOT included: the days / times when they are clouded out or they do some technics.
But... ...good that you ask... I forgot that I was NOT online from 2008-05-26 to 2008-05-29...
Correction 2008-06-09: (O.k. - my brain is sorted new... : I modified the date from 30 to 29. When I was online on 2008-05-30 there was still the old result online from 2008-05-16. So I was sure that the detections from yesterday have been the first detections this year.)
