Minor geomagnetic storm 18th June 2018

Raised solar wind speeds, increased particle density and a southerly magnetic orientation sparked a minor geomagnetic storm (G1, Kp5) which was detected on my magnetometer. The wind originated from a moderate coronal hole in the solar atmosphere, now rotating away from us.

Things have been pretty quiet of late.

Thanks for looking.

Well caught Stuart :bow clouded out here but then it doesn't get dark till after midnight anyway. I am still on the hunt for noctilucent clouds but I still haven't seen any. There was supposed to be lots last night but cloudy as usual.
