Tomorrow might be a washout in the North West for the lunar eclipse, but with the high expectation of thunderstorms, there could be sprites. These phenomena are extremely rapid and are best photographed.
The place to look for sprites is above the tops of distant thunderheads. Sprites might be linked with cosmic rays that strike the top of the atmosphere, creating secondary electrons that trigger upward bolts.
Cosmic rays are increasing in intensity due to the solar minimum with its weakened magnetic field, so the chances of observing sprites are greater.

Of cause, we all hope the forecast is wrong.

It would be nice to witness both phenomena Paul: the eclipse with episodes of fire and brimstone. :D

We didn't stand a chance yesterday evening.
Skies were cloudy and grey with a gusty wind (too many balloons) But here's something.

Macclesfield and surrounding area. Missed the worst of the weather :D
