Hi Len, Yes the sky here was pretty murky too. There was a bit of brightening but one can never be sure under such circumstances! It looks like we're in for another week of pretty poor weather here's hoping it clears for the following week, peak season! cheers, Bill.
Fairly clear 0130-0200 this morning, first time it's not been clouded-up since the 3rd, but (albeit not with a great view north due to being in the Dyfi valley) it appeared to be all quiet. Having slept through the pre-Midnight period I cannot say whether this represents a full N.O. but little seemed to be occurring.
Negative for NLC from Elland, West Yorkshire this morning 11/07/2011 twixt 01:00 UT and 01:50 UT with a useful north horizon .Like John I slept through the pre-midnight period ( no chance for grabbing a daytime nap on Sunday and I had been busy NLC ing the night before ! ). Len E
Missed the post-sunset slot tonight but checked out the pre-dawn one & nothing doing here. Think July 14-15 counts as a no-no.
Cheers - John
I think that goes some way to demonstrating the need for caution in using observer reports. Does a reported time bracket (say, 01:00-02:00) mean that the display started and then faded during that period, or does it merely represent the period the person could observe? We can't tell, and often, there aren't enough reports from similar latitudes close enough together also in longitude to allow the story to be 'filled in'.
Again, given the propensity for internet indignation to set-in, this is an observation on the potential weakness of observations for scientific purposes, not a criticism of observers themselves. We all do what we can, and what we do is very demanding!
No - that's a good point. There may have been a post-sunset showing.
Having said which, there appears to have been a tendency for the pre-dawn shows to be the more intense ones but I say "appears" pointedly! There are so many variables such as timing and distribution of tropospheric cloud-cover, observer stamina.availability and so on! The great things about satellites is a) they're above all cloud and b) they don't need sleep!
Hi, A couple of nice evenings but nothing seen 22.30UT-01.00UT on 22/23 July and 22.30-01.30UT 23/24 July. Skies now much darker around midnight. The season looks like its shaping up to have been quite a short one this year, still a few weeks to go though. Cheers, Bill.
