But, as I posted earlier (1999). This pic looked damn near a total eclipse. Ok, not a total though. Looks more like about 98% to me. Must've gone blind looking at it back then :-)
On 20 Mar 2015, Graham. grunted:
Last night having looked at the gloomy weather forecast here and decided it wasn't worth expending effort on sorting out eclipse-viewing gear; and further more that I'd be up and about for a good hour or so anyway before anything interesting started happening, so worse-case-scenario I'd work something out in the morning in the event of clear sky.
This morning, worst fears were confirmed - 100% cloud cover, so I just got stuck into my cornflakes and newspaper. Then suddenly, at about 9.15, BAM! bloody hell, the sun suddenly broke through; so there's me and SWMBO (who of course had told me to me to get organised last night notwithstanding) frantically rushing round the house looking for binoculars, tripod etc and fabricating cardboard shields. We were just in time to be able project the near-totality image on to a pale wall using hand-held binocs, which was all a bit crap really!
Last time we went camping in Germany in the totality zone; we obviously got the darkness, but sadly under 100% cloud cover.
When's the next one then? :(
All here:
Well I think if the sun was visible it might have looked much better too much diffusion thru the overcast cloud, just got a bit darker here and that was that. However the clouds vanished an hour later and the olde Sun was smiling down on us as if to say,
"Did yer like that then";?.
As old Fred Dibnah might have muttered once or twice, thrice even!..
How hard is it to get out the welding mask?
:o)
Even under a cloudy sky, the total eclipse I saw in 1999 was awesome.
Everybody with me in that field in Truro, were visibly moved with the experience.
Well worth the 12 hour round-trip from Manchester.
Drivel. I predicted it would be a non-event. Good visibilty here in the W. Midlands. Watched with electric welding visor Tried to take pix through the visor but camera wouldn't focus. It didn't get that dark. If it had been cloudy or no means of viewing, the eclipse would not have been at all noticable. PV panels did not shut down, lost maybe a Kwh of electricity production. If it have been midday I'd maybe have lost 2Kwh. (Assuming "good" day).
If it had been a total eleclise, the panels would have shut down, it takes about ten minutes for them to restart. So maybe would have lost maybe 3Kwh.
2017 USA looks a good one in terms of plenty of places to watch from.
I noticed that on gridwatch
It's to account for people having a cuppa while/after watching the eclipse, apparently there was a 3GW spike in 1999 and there wouldn't have been any PV needing 'cover' back then.
I looked but the moon was in the way.
You get the same many times a year, it turns night. A total eclipse has to be seen its not just the sky going dark.
It was very cloudy here and I gave up all hope of taking a picture, but the clouds cleared just in time and I took this:
It was taken on auto focus, auto exposure minus two stops. Metering was centre weighted. I cropped it a bit to get rid of a phone wire, and tweaked the gamma a bit.
I took a few close-up ones, and they showed the irregular surface of the moon. Well I think they did anyway.
I experimented taking a pic through welding glass but the exposures were too long.
Thing is, I wonder if the temperature change causes the clouds to clear. It was funny how the hole appeared in the cloud just at the right moment.

I'd have thought a temperature drop would have caused cloud formation. Cold air can't hold as much water vapour so it condenses into cloud, at least at low levels (up to few thousand feet), the atmosphere may behave differently at higher levels, 10,000'.
Having watched the time lapse here, the half hour ish before maximum sees things get very murky and the cloud decend almost down to us and a heavy mist forming. The half hour after sees the same in reverse, the mist disappears and the cloud base rises. Rest of the day is fairly stable, with occasional small breaks in the cloud, that remained well above us. Very much like the couple of hours from dawn to eclipse.
Did the eclipse bring on the murk?
Depends how you define spike.
The wonkypedia
Which has figures giving a 2.35 GW drop in demand over about 45 mins then a very rapid rise of 3 GW but only 650 MW of "new" demand. I wonder which the grid finds the hardest to handle, this drop and rise with relatively little extra generation being required or a rise post a football match or wedding that needs nearly 3 GW of "new" generation to prevent the lights going out.
As anyone who had ever sat through a partial eclipse before could have told them
It's not like partials are rare, there was one every 3-4 years when I were a lad
The current group of journos were spoilt. They were just starting out in 99 and there's been nothing since to "learn em" that anything less than total is, comparatively, a non event

What a superb picture the sun in that gap like that framed by the trees.
You should have sent that to Aunty BBC.. Oh!, hand on perhaps best not;!...

That's definitely a real prize-winner.

Excellent picture Bill Well done.
