Sunspots rotating into view, waning CME effects
A cluster of moderately large sunspots is now rotating into view on the north-east limb and these sunspots have already been the source of a couple of C-class solar flares during the past 24 hours. It is unclear if these sunspots belong to one large sunspot region or if there are multiple regions close to each other and it is still too early to analyse the magnetic layout of this area as the sunspots are still too close to the limb.
Current data suggests there is a moderate possibility for aurora to appear at the following high latitude regions in the near future

Coronal hole faces Earth
The anticipated strong G3 geomagnetic storm watch never materialized as the coronal mass ejection that was supposed to arrive early yesterday didn't arrive until today just past midnight UTC. The impact was very lackluster with the Bt (total strength of the IMF) increasing to a moderate 15nT at best and the solar wind speed reaching just 420km/s. A far cry from the anticipated 700 to 800km/s. That once again goes to show how hard it is to forecast space weather events and any resulting geomagnetic conditions. We remain under the influence of the CME and high latitude sky watchers should remain alert for some nice aurora displays but middle latitude sky watchers will probably have to wait for the next opportunity.
13:55 UTC - Coronal hole
A transequatorial coronal hole is facing Earth. Enhanced solar wind could arrive in ~3 days

Active geomagnetic conditions (Kp4) Threshold Reached: 02:33 UTC
