Aurora Watch
A coronal hole stream is now beginning to move past Earth. A geomagnetic enhancement, possibly reaching minor (G1) storm levels will be possible at higher latitudes during the next 24 hours. Sky watchers with clear skies should be alert for visible aurora.

Next Coronal Hole Takes Aim
A large, oddly shaped coronal hole will begin to face Earth over the next few days and this means another high speed solar wind stream will be directed towards Earth. Another round of geomagnetic storming will be possible beginning November 9th and into the weekend. Aurora sky watchers at higher latitudes should be alert.

Coronal Hole Stream / Moderate Storm Watch (UPDATED)
A little later than expected, but a coronal hole stream containing a predominantly south pointing Bz is now moving past Earth. Enhanced geomagnetic activity will be possible during the next 24 hours.

UPDATE: A minor geomagnetic storm is now in progress at higher latitudes. A watch for Moderate (G2) storming is also now in effect. Aurora sky watchers with clear skies should be alert once it is dark outside.

Geomagnetic Storm Watch (UPDATED)
A large coronal hole is now facing Earth. Because of this feature, a high speed solar wind stream is expected to reach our planet within the next 48 hours. Minor (G1) geomagnetic storming will be possible at high latitudes. There may also be a smaller chance for isolated moderate (G2) storming as well depending on the dynamics of the incoming solar wind stream. Visible aurora will be possible this weekend. More to follow whenever necessary.

UPDATE @ 01:00 UTC Nov 4: As of this update, the anticipated coronal hole stream has yet to arrive past Earth. A solar wind increase should still be expected on Sunday and could still lead to a geomagnetic enhancement at higher latitudes.
