14-04-13 Geomagnetic Storm Update HD

Best viewed with window expanded.
The lights dimmed. Something I take so naturally in stride over the years and just smile to myself when these events occur, the Geomagnetic Storm. Ground based magnetometers detected a geomagnetic sudden impulse measuring 29 nT at 22:57 UTC and this signals the passage of an expected Coronal Mass Ejection passed our planet. The ACE spacecraft initially detected a solar wind increase to near 500 km/s at 22:20 UTC.
We might say hmmmm that's not very strong, well it isn't over yet we have until the 15th inclusive to measure the strength of the plasma cloud impacting our geomagnetosphere. (This is basically a continuation from yesterday with its updates)
Enjoy ;)
