Solar Update
Good evening. Solar activity declined to somewhat lower levels during the past 24 hours following a pair of M1 solar flares very early Thursday morning. Region 2567 continues to produce occasional C-Flares and will remain a threat for an isolated M-Flare as the cluster moves closer towards the western limb. Attached image below courtesy of SDO/HMI. Stay tuned to SolarHam.com for the most up to date spaceweather news, data and imagery.

M1.2 Solar Flare / Region 2567
It's been a while, but the first M-Flare since April 18th was just detected around region 2567 at 00:46 UTC (Jul 21). This flare (M1.2) was in addition to a number of C-Flares this evening, including a C4.7 flare at 22:17 UTC (Jul 20). More updates should a coronal mass ejection be associated with any of these events. The active region continues to move out of a geoeffective Earth facing position with every passing day.

UPDATE: An Earth directed CME was not associated with the events listed above. An impact to our geomagnetic field is unlikely.

CME Passage / Storm Warning
A CME shock passage was observed Tuesday evening by the ACE spacecraft. A geomagnetic sudden impulse was detected at 23:55 UTC (Jul 19) signalling the passage past Earth. Minor (G1) geomagnetic storming is currently being observed at higher latitudes. A watch for moderate (G2) storm conditions will be in effect until 06:00 UTC (July 20).

WARNING: Geomagnetic K-Index of 6 expected
Valid From: 2016 Jul 20 0030 UTC
Valid To: 2016 Jul 20 0600 UTC
Warning Condition: Onset
NOAA Scale: G2 - Moderate

SUMMARY: Geomagnetic Sudden Impulse

Solar Update / Region 2567
Good evening. Solar activity remained at fairly low levels during the past 24 hours. Region 2567, now directly facing Earth, was able to produce a long duration C6 solar flare at 23:35 UTC (July 17). So far it does not appear that a noteworthy coronal mass ejection (CME) is associated with this particular event. There will remain a small chance for an isolated M-Flares while the active region directly faces our planet. Elsewhere, a new sunspot is forming in the northeast quadrant and appears stable for now. Stay tuned to SolarHam.com for the latest spaceweather data and imagery. Attached image below of the C6 solar flare courtesy of SDO/AIA.

Solar Update / New Sunspots
Good morning. Here is an updated look at the visible disk on Friday. Solar activity is currently at very low levels, although we could see an increase with the addition of new sunspot 2567. The region formed just behind region 2565 and could possibly produce minor C-Flares. There is also a small chance (5%) for an isolated M-Flare according to NOAA/SWPC. All other visible numbered regions are currently stable. No Earth directed coronal mass ejections were observed during the past 24 hours. Stay tuned to SolarHam.com for the latest spaceweather data and imagery.

Solar Update
Hello again folks. Solar activity was very low during the past 24 hours with no noteworthy solar flares to report. Region 2564 showed some signs of minor decay, whereas region 2563 did develop a few new spots. Region 2562 in the southeast quadrant is currently stable. There will remain a chance for minor C-Class solar flares. A new sunspot is turning into view off the east limb and was assigned number 2565 this morning. So far it appears to be a magnetically simple "Alpha" region, however we will need to wait another day or so to get a better look.

A minor (G1) geomagnetic storm watch will be in effect during the next 24 hours. A coronal hole high speed solar wind stream is expected to become geoeffective. Stay tuned to SolarHam.com for the most up to date information.

Our friend Alex Dzierba sends us the nice imagebelow showing region 2564, along with 2565 that he captured from his location in Hawaii. Thanks for sharing!

Solar Update
Good morning. Solar activity during the past 24 hours remained low, although region 2564 was responsible for a C8.6 solar flare at 00:59 UTC (July 10). There will remain a chance for minor C-Flares during the next day with a smaller chance for an isolated M-Flare. Stay tuned to SolarHam.com for the most up to date spaceweather data and imagery.

New Sunspots / Storm Watch Continues
Good evening. Minor geomagnetic storming was observed during the past 24 hours as a high speed solar wind stream remains geoeffective. Isolated periods of storming will remain possible during the next 48-72 hours.

Solar flare activity remains at lower levels, although an increase may be possible with the addition of region 2564, now turning into view off the east limb. Stay tuned for the latest update. Attached image below courtesy of SDO/HMI.

Solar Update / Storm Watch
Good evening. A coronal mass ejection (CME) observed Tuesday evening was directed to the west and away from Earth.

A couple of small sunspots (2559 and 2560) were numbered yesterday. Although enough to break the spotless sun streak, they both faded away within the past 24 hours. A new sunspot may be forming in the southwest quadrant and will be monitored. Attached image below courtesy of SDO/HMI.

Lastly, an enhanced solar wind stream is now becoming geoeffective. A minor (G1) geomagnetic storm watch will be in effect for the next 24-48 hours.

Filament Eruption and CME
A filament eruption Tuesday evening in the northwest quadrant looks to be responsible for a coronal mass ejection (CME) now visible in the latest LASCO C2 imagery. So far it appears to be headed mostly towards the west, however further updates will be provided once complete imagery becomes available. Stay tuned.

Solar Quiet / Coronal Hole
Good evening. Apart from a couple of very small pores, the visible disk remains spotless for the 12th day in a row. Solar activity is likely to remain at very low levels. Geomagnetic storming failed to materialize during the last watch from a few days ago. Another coronal hole (#93) will become geoeffective by the upcoming weekend and perhaps bring another watch into play. More updates in the days ahead. Image below courtesy of SDO/AIA.

July 3, 2016 @ 00:45 UTC
Solar Update
An expected coronal hole solar wind stream is now geoeffective. An isolated period of minor (G1) storming will be possible at higher latitudes. Conditions are expected to decrease to quieter levels within the next 24-48 hours.
