This was a highly active storm cell passing up the eastern side of the Pennines and was spotted directly east of Macclesfield. Because it was dark you could see the distant continuous flickering with the naked eye (often referred to as “Heat Lightning” as it lights up the atmosphere around it). I made an attempt to capture it with the camera but it didn’t show up very well as it was too faint. Only one brighter flash was caught but even that wasn’t impressive enough to do a screen grab for you. The discharge rates were high around 5-10 seconds. It was coupled with another cell to the NE which discharged about once every 2 minutes, and every time it did, the higher-powered cell to the east flickered in return, so it looked like they were communicating with each other.

There was obviously no thunder as it was so far away. If I wasn’t as impressed as I was with the discharge rates, especially given the time of year, I wouldn’t have logged this storm. I thought it was worth noting in case someone else remembers experiencing it that lives on the other side of the Pennines.
