|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.

|Coronal Hole to Face Earth (UPDATED)|
Good evening. A middle latitude coronal hole (#88) will become geoeffective after May 15th. Enhanced geomagnetic activity will be possible once a high speed solar wind stream arrives past Earth. Visible aurora may be possible beginning Monday.|
UPDATE: A minor (G1) geomagnetic storm watch was added for May 16th. More updates to follow in the days ahead.

Good evening. Solar activity remains at very low levels with no noteworthy solar flares to report. Both regions 2654 and 2655 are expected to remain stable over the next 24 hours.|
Geomagnetic activity is also at quiet levels and no major geomagnetic disturbances are currently in the 72 hour forecast window. Stay tuned for the last information.
