Minor Geomagnetic Storm
According to the Space Weather Prediction Center (SWPC), a minor (G1) geomagnetic storm is suddenly in progress. A coronal hole stream was expected to move past Earth over the next several days.

ALERT: Geomagnetic K-index of 5
Threshold Reached: 2020 Aug 28 1759 UTC
Synoptic Period: 1500-1800 UTC
Active Warning: Yes
NOAA Scale: G1 - Minor

Aurora Watch
A series of narrow coronal holes are now beginning to partially face Earth. An elevated coronal hole stream should begin to move past Earth by August 29th and could lead to visible aurora at higher latitudes. A geomagnetic enhancement (Kp4) is currently in the forecast with a lesser chance for a minor (G1) geomagnetic storm.

CME Update
A slow moving coronal mass ejection (CME) observed on August 16th likely missed our planet and is no longer expected to deliver a glancing blow to our geomagnetic field. Widespread aurora beyond the Arctic (and Antarctic) circles will be unlikely tonight.

Eruption Observed (UPDATED)
A minor eruption measuring as a low level B-Flare was observed on Sunday around a plage region located in the southeast quadrant. A coronal mass ejection (CME) is associated, but so far looks to be headed mostly to the east and away from Earth. Another update will be provided once additional coronagraph imagery and a tracking model becomes available.

UPDATE: According to the Space Weather Prediction Center (SWPC), a glancing blow CME passage is predicted by August 20th. A minor geomagnetic disturbance may be possible within the next 72 hours.

Minor Solar Flare (UPDATED)
A minor solar flare measuring C2.0 was detected early Saturday at 06:47 UTC. The source was plage region 2770, now turning towards the northwest limb. A large coronal mass ejection (CME) is unlikely, however another update will be provided if necessary.

Coronagraph imagery reveals a weak coronal mass ejection that is heading to the west and away from our planet.

Solar Update
A new active region (AR2771) belonging to Cycle 25 is forming in the southeast quadrant today and will be monitored. A secondary region is now turning into view off the southeast limb and appears to be spotless for now. Image below courtesy of SDO/HMI.

Another Sunspot
Solar activity remains at very low levels as we head into Friday. The lone spotted region AR 2770 has been trying to form a few trailing spots today, but so far remains a magnetically non threatening region. There will remain a low chance for a minor C-Flare during the next 24 hours. Image below by the Solar Dynamics Observatory (SDO).

Aurora Watch
A coronal hole stream is currently moving past Earth above 500 km/s and is helping to stir up geomagnetic activity at higher latitudes. Sky watchers should be alert for visible aurora tonight should local weather and light conditions allow.

Another Sunspot
Hello and welcome to August!

Another region turned into view off the northeastl imb and looks to be sprouting a few small spots. Even a low level B-Flare was detected within the past hour. Should this region stick around long enough, it will be assigned AR 2769. The uptick in Cycle 25 activity continues. Image by SDO/HMI.
