What happened to the storm? (UPDATED)
The past several days were supposed to include geomagnetic storming, however that did not obviously pan out. There will remain a chance for storming however when a high speed solar wind stream flowing from a larger coronal hole is predicted to reach Earth within the next 24 hours. More updates whenever necessary. High latitude aurora sky watchers should continue to be alert.

Moderate Storm Watch / Aurora Possible
Good evening. Coronal Hole #88 is now facing Earth and a solar wind stream flowing from this zone should reach Earth within the next 24 hours. Minor (G1) to Moderate (G2) geomagnetic storming will be possible at higher latitudes during the next 48 hours. High latitude sky watchers should be alert for visible aurora during this period.
