The 777 Mile "Cloud"

 

This only shows about 1/4 of it's actual size

This is the other 1/4 on the left side of it

Geomagnetic Biologist Alfredo Kabil  “Just spotted what appears to be the largest shelf cloud on record to date. It is proportional to the size of Kamchatka peninsula Russia.” 

The Kamchatka Peninsula is 1,250-kilometre-long [777 miles]

But I think he only saw part of it.

It's the base cloud of the planet Napisiti.   It's always exactly the same shape, with the same blue/green light, and if it's coming at you, you'll know it.

 

I've seen it coming towards me, I tracked it coming in from the west because I'd seen the images coming up on FB and then I watched the radar, and sure enough it came in from the west, like a living breathing entity, moving like it was alive, pulsating and emitting pink horizontal lightning from the base.  It is absolutely breath-taking.  The videos below will give you some idea, but nothing like the real thing.

Oh, and the thunder is 10 times that of normal thunder.  You can hear it coming, like an express train, from many miles away.  And then it might pause and just stay in place before continuing on it's journey.

All these videos are in different countries.  There are literally thousands of videos of this thing.  Sometimes it drops rain bombs.
