Moderate G2 geomagnetic storm

Moderate G2 geomagnetic storm

The anticipated coronal hole solar wind stream really packed a punch and gave us moderate G2 geomagnetic storming conditions yesterday. The solar wind stream turned out to be stronger than anticipated as only minor G1 geomagnetic storm conditions were expected! The north-south direction of the IMF (Bz) dropped down as low as -17nT yesterday which is very respectable for a CIR ahead of the coronal hole solar wind stream.

 bWe are still occasionally reaching the minor G1 geomagnetic storm threshold today as the solar wind speed remains high (between 700 and 750km/s at the moment) but we are not expected stronger storm conditions than the this.

Fantastic auroral displays were seen at many high latitude locations today and yesterday. Even folks at upper middle latitudes locations managed to capture some aurora. Below we have a couple of images. Enjoy!
