Strange cloud

Rubbish quality apologies but it was pretty dark out and only had phone to hand.

No wind. Not a cloud in the sky. Well, except this one which appeared to be moving and shrinking and quickly disappeared.

But long after there was a real flurry of satellite activity with umpteen in quick succession travelling NW to SE and a few travelling N to S and a couple going from SW to NE!

Then a literal string of satellites zoomed across the sky from NW to SE evenly spaced. Maybe 30 of them! Presume they were starlink satellites but did start to wonder how much repositioning of military satellites must be going on right now :/
