Solar Update
Good evening. Solar activity remains very low with nothing of interest to report. Region 2635 continues to slowly decay as it rotates across the northwest quadrant.

Coronal Hole 63 will become geoeffective over the next few days. A solar wind flowing from this zone is expected to skirt past our planet and may lead to enhanced geomagnetic activity at higher latitudes. Geomagnetic storming is not currently in the forecast.

Solar Update
Following the quick emergence of region 2635 a few days ago and a few minor C-Flares, the region stabilized and solar activity declined back to very low levels. Only an isolated C-Flare will be possible during the next 24 hours. Geomagnetic activity around the polar regions is also expected to be fairly quiet during the next few days. More updates whenever necessary.

Solar Update
Good evening. Been very quiet on the sun the past few days with the visible disk briefly going spotless. A new sunspot (2635) is now forming in the northeast quadrant and will be monitored. An isolated minor C-Flare will be possible as the region evolves. Image below courtesy of SDO/HMI. Stay tuned to SolarHam.com for the most up to date spaceweather news, data and imagery.

Solar Update
Good evening. With the exception of inactive sunspot 2632 which will soon turn out of view, the visible disk is is now void of sunspots. Solar activity is expected to remain at very low levels in the short term.

A high speed solar wind stream continues to decrease as coronal hole 58 is no longer facing Earth. Geomagnetic activity should also continue to gradually decrease over the next 24 hours. Visible aurora will remain possible around the Arctic Circle. Stay tuned to SolarHam.com for the most up to date spaceweather data and imagery.

Icelandic Aurora
Enhanced geomagnetic activity continues on Thursday while a high speed solar wind stream remains geoeffective. Visible aurora is being reported by many at higher latitudes and this could persist for the next 12-24 hours. Below is a stunning self photo courtesy of Jon Dickson who captured the image last night from Westfjords, Iceland. Nicely done and thanks for sharing! Stay tuned to SolarHam.com for the latest information.

Geomagnetic Storm Watch (UPDATED)
A high speed solar wind stream above 600 km/s is now moving past Earth. Enhanced geomagnetic activity, possibly reaching minor (G1) storm levels will be possible during the next 24 hours. Sky watchers at higher latitudes should be alert for visible aurora.

UPDATE (00:00 UTC Feb 1): A minor (G1) geomagnetic storm is currently in progress thanks to a high speed solar wind stream above 700 km/s. Aurora sky watchers should be alert once dark outside.
