Sunspot 2671
Good evening. Here is a look at new sunspot 2671 as it turns into view off the east limb. The active region in formation is currently producing minor C-Class flares and depending on additional development, it could potentially produce an isolated M-Flare. Image is courtesy of SDO/HMI. More updates whenever necessary,

Solar Update
Solar activity remains at very low levels. Region 2670 is magnetically simple and not considered a threat from strong solar flares.

Geomagnetic activity is also quiet and is expected to remain so for the next few days. Widespread aurora is not in the short term forecast.

Storm Watch Update
A coronal hole stream is now moving past Earth above 600 km/s. As of this update, only disturbed (Kp4) geomagnetic conditions have been observed. A minor (G1) geomagnetic storm watch will remain in effect for the next 24 hours.

Moderate Storm Watch / Coronal Hole
Alright, so region 2670 (ex 2665) is no longer considered to be a major flare threat. Now what?

How about a moderate (G2) geomagnetic storm watch?

A high speed solar wind stream flowing from the middle latitude extension of coronal hole #18 is expected to become geoeffective by late Friday night (August 4). Geomagnetic storming will be possible at higher latitudes. More updates this weekend. Image below by SDO/AIA.

The Return of 2665 (Updated)
Right on schedule, old sunspot region 2665 is now turning back into view off the east limb. Minor B-Class and low level C-Class flare activity is now being detected. We will get a better look during the next 24 hours. Image courtesy of SDO/HMI.

UPDATE: Old region 2665, now reassigned 2670, appears to be greatly decayed and may no longer be a threat for noteworthy solar flares. More updates whenever necessary.
