Coronal Hole Faces Earth (UPDATED)
Good evening. Coronal Hole # 42 is now facing our planet. A high speed solar wind stream flowing from this zone is expected to reach Earth beginning November 20th. Enhanced geomagnetic activity (Kp4) and possibly an isolated period of minor (G1) storming (Kp5) will be possible at higher latitudes. Sky watchers should be alert for visible aurora during the next 48-72 hours. Image courtesy of SDO/AIA.

Minor Storm Watch
A minor (G1) geomagnetic storm watch is in effect for the next several hours as an elevated solar wind stream moves past our planet. High latitude sky watchers should be alert for visible aurora.

Valid From: 2017 Nov 16 0500 UTC
Valid To: 2017 Nov 16 1200 UTC
Warning Condition: Onset
NOAA Scale: G1 - Minor

Solar Update
Stop the presses!

After nearly two weeks of no visible Earth facing sunspots, a new region is now rotating into view off the southeast limb. So far the sunspot does not appear to be a threat for noteworthy solar flares and overall activity should continue at very low to low levels (minor C-Flares). Image courtesy of SDO/HMI.

Solar Update
Good morning. Periods of minor (G1) geomagnetic storming continued during the past 24 hours as a high speed solar wind stream moves past our planet. Currently the solar wind remains elevated above 550 km/s and isolated periods of minor storming will still be possible during the next few days. Ian Johnson shares with us this stellar aurora photo that he captured from Juneau, Alaska. Thanks for sharing!

Moderate (G2) Storm in Progress
A high speed solar wind stream nearing 700 km/s is helping to stir up a nice Moderate level (G2) geomagnetic storm as we head into Wednesday, Sky watchers across Scandinavia, northern Europe, UK, Canada, northern tier USA and Alaska should all be alert for visible aurora once dark outside.

Below is an awesome new photo captured early Tuesday by Sacha Layos from up in Alaska. Great job!

Bz South / Solar Wind Update
The Bz component of the interplanetary magnetic field (IMF) is currently pointing south as the solar wind speed gradually increases. Geomagnetic storming will be possible during the next 24 hours. Sky watchers at higher latitudes should be alert for visible aurora if dark outside.

Solar Update / Minor Storm Watch
Good evening. Solar activity continues at very low levels with no noteworthy activity to report during the past several days. The visible disk remains void of sunspots.

A high latitude coronal hole is now facing Earth. A solar wind stream flowing from this zone is expected to reach our planet by November 7th and may generate Minor (G1) geomagnetic storming at higher Earth latitudes. More updates in the days ahead. Image courtesy of SDO/AIA.
