G2 - Moderate Geomagnetic Storm, Aurora Seen as Far South as Colorado ~ The Watchers ~ 22 April 2017


Think of all the Divine Codes we are being fed through all this Solar and Cosmic Winds.... I believe that even if these events are not Earth-facing, we are still affected in some way. Our transformational process is now continuous and full-on!

A potent coronal hole has become geoeffective and possibly in a combination with an April 18 CME is causing geomagnetic storms reaching G2 levels. This is the second of two geoeffective coronal holes to affect Earth this week. The effects are expected to persist through April 24.

The solar wind parameters during the past 24 hours were indicative of waning influence of positive polarity coronal hole high speed stream (CH HSS), the first to affect Earth this week. After 11:00 UTC on April 21, observatories detected an enhancement in solar wind parameters, possibly from the periphery of a coronal mass ejection (CME) produced on April 18. This CME was not expected to affect Earth, as models showed it had no geoeffective component. However, it seems it was partially Earth-directed and our magnetic field received a glancing blow.

The total magnetic field strength (Bt) was near 5 nT at 11:15 UTC on April 21, when a steady increase to a peak of 14 nT at 16:13 UTC was observed. Bz was variable between +13/-11 nT, with a maximum southward value observed at 15:47 UTC. The solar wind environment decreased from 550 km/s to a low of 453 km/s around 11:15 UTC. Afterward, an abrupt increase in winds speeds occurred to a peak of just under 700 km/s at 20:50 UTC. Phi angle transitioned from the positive sector to the negative sector after 15:45 UTC.

The greater than 2 MeV electron flux briefly reached high levels with a peak flux of 2,810 pfu observed at 15:45 UTC on April 21. The greater than 10 MeV proton flux remained at background values.

The geomagnetic field reached G1 - Minor storm levels at 20:32 UTC, due to the likely passage of a transient feature combined with the onset of a co-rotating interaction region (CIR) preceding CH HSS influence.
