Geomagnetic Storm Watch (UPDATED)
An upgrade to the Moderate (G2) geomagnetic storm watch threshold was just released by the NOAA Space Weather Prediction Center (SWPC). The increased activity is expected to begin on Saturday (Aug 31) and would be the result of an expected coronal hole stream past Earth. More to follow this weekend.

Larger Coronal Hole to Face Earth
The next coronal hole in line will begin to face Earth during the next few days. This "T" shaped hole in the suns atmosphere should be the source of a high speed solar wind stream past Earth beginning this upcoming weekend. Perhaps some good news for high latitude aurora sky watchers. Image below by SDO/AIA.

Coronal Hole to Face Earth
Hello again folks. Been a while since I've last posted an update. Solar activity has been pretty much at a standstill with nothing noteworthy to report up until today.

A coronal hole (56) located near middle latitude will begin to turn into an Earth facing position over the next several days. A solar wind stream flowing from this hole may reach Earth by the middle of next week and could possibly boost geomagnetic activity around our polar regions. More updates to follow whenever necessary. Image by SDO/AIA.

Geomagnetic Storm in Progress
An expected coronal hole stream is now moving past Earth near 600 km/s. Minor (G1) geomagnetic storming is being observed at high latitudes.

ALERT: Geomagnetic K-index of 5
Threshold Reached: 2019 Aug 05 0813 UTC
Synoptic Period: 0600-0900 UTC
Active Warning: Yes
NOAA Scale: G1 - Minor

Another Coronal Hole Faces Earth
Another coronal hole (48) is now beginning to directly face Earth. A high speed solar wind stream flowing from this hole should likely reach Earth by August 5th. Enhanced geomagnetic activity, possibly reaching minor (G1) storm levels will be possible at higher latitudes. More to follow.
