Geomagnetic Storm Watch Issued
A pair of coronal holes stretching across the southern hemisphere are now turning into a geoeffective position. A solar wind stream flowing from these holes could reach Earth within the next 48-72 hours and lead to elevated geomagnetic at higher latitudes. A minor (G1) geomagnetic storm watch beginning on July 31st has been issued by the NOAA Space Weather Prediction Center (SWPC). More updates in the days ahead.

Oh So Quiet
Good morning. Below is a look at the not so active Earth facing side of the sun on Wednesday. Both numbered regions are quiet and non threatening. No Earth directed coronal mass ejections were observed during the past day.

So what can we expect in terms of solar activity during the upcoming months and years? A look at the smoothed solar flux and sunspot data will tell us that we are now exiting the second peak of the current solar cycle 24 and may very well be in the early stages of a slow decline to solar minimum. This does not mean that we have seen the last of large sunspot groups and big solar flares however. Spikes in activity will remain likely while make the long transition to the predicted solar minimum around 2019-2020.

Solar Update
Good morning. Below is an updated look at the visible solar disk on Sunday. Solar activity in terms of X-Ray flares remains at relatively low levels. All three visible sunspot regions are quiet and non threatening at this time. A pair of filament eruptions were observed during the early hours of July 19 (UTC). The first took place in the northwest quadrant beginning at 01:45 UTC, while the second occurred towards the southwest limb at 08:30 UTC. A faint coronal mass ejection (CME) is seen leaving the sun following the first event and so far appears to be headed away from our planet. The second event will likely be directed away as well. More to follow if necessary. Stay tuned to SolarHam.com for the latest information.

The Quiet Continues
Good morning folks. Here is an updated look at the visible solar disk on Friday. Solar activity continues at very low levels with no noteworthy solar flares to report. Region 2387 did show minor growth during the past day and could produce isolated C-Flares. All other numbered regions remain quiet. No Earth directed coronal mass ejections were observed during the past day. Stay tuned to SolarHam.com for the latest information.

Quiet Times
Good morning. Here is an updated look at the visible solar disk on Wednesday. Solar activity is at very low levels with no noteworthy solar flares to report. What remains of region 2381 is now turning onto the west limb and out of direct Earth view. A new sunspot is turning into view off the east limb and so far appears to be stable. We will get a better look at it during the next day or so. Geomagnetic activity is also at quieter levels with no storming currently in the forecast. Stay tuned to SolarHam.com for the latest spaceweather data and imagery.

Solar Update
Good morning folks. Solar activity on the sun is at very low levels on Sunday morning. The visible disk is down to three numbered regions, although what appears to be a relatively small sunspot is now turning into view off the east limb. There will remain a chance for minor C-Class solar flares. No Earth directed coronal mass ejections were detected during the past day.

Geomagnetic Storming Observed
An expected solar wind stream containing periods of southward Bz, currently above 500 km/s, is now streaming past Earth. Minor to Moderate geomagnetic storming is being observed at higher latitudes. Sky watchers should be alert for visual aurora tonight if it is dark outside.

Solar Update / Geomagnetic Storm Watch
Hello and welcome to another Friday. Solar activity during the past 24 hours was very low with no noteworthy solar flares to report. New region 2385 formed rapidly in the northwest quadrant and will be monitored. There will remain a chance for at least C-Class solar flares with regions 2381 and 2385 being the most likely to flare. A filament located high in latitude in the southern hemisphere erupted very early Friday morning (UTC). A coronal mass ejection (CME) became visible in the latest LASCO coronagraph imagery and appears to be headed well south of the ecliptic plane. An impact to our geomagnetic field is unlikely.

A minor geomagnetic storm watch will be in effect during the next 24-48 hours. A co-rotating interactive region (CIR), along with a coronal hole solar wind stream are expected to become geoeffective. Sky watchers at high latitudes should be alert for visual aurora.

Solar Update
Good morning. Here is an updated look at the visible solar disk on Tuesday. Solar activity during the past 24 hours was moderate. Region 2381 produced an M1.7 solar flare at 20:40 UTC (July 6). Only low level C-Flares were detected ever since. The active region decayed somewhat, but will remain a threat for an isolated M-Flare as it continues to evolve in the northeast quadrant. All other visible numbered regions are stable. A new active region off the southeast limb, perhaps the source of a coronal mass ejection observed on Monday, is now turning into view. We will get a better look during the next 24 hours. Stay tuned to SolarHam.com for the latest information.

Solar Update
Good morning and a happy 4th of July to my American friends to the south. I hope you all have a great day!

Solar activity on Saturday morning is at very low levels. All visible sunspot regions are currently stable. New regions 2380 and 2381 were numbered overnight. There will remain a chance for minor C-Flares and a low threat for an isolated M-Flare. No Earth directed coronal mass ejections were detected during the past day. Stay tuned to SolarHam.com for the latest information.

M1.5 Solar Flare / Minor Storm Watch Added
Good morning. Here is an updated look at the visible disk on Friday. Solar activity during the past 24 hours reached moderate levels. Region 2378, now turning into view off the southeast limb, produced a number of minor C-Flares, along with an impulsive M1.5 solar flare at 12:51 UTC. Additional minor C-Flares were also detected around regions 2373 and 2376. The threat for another isolated M-Flare will remain in place, with regions 2376 and 2378 being the most likely source.

As I first reported on Thursday afternoon, a large prominence eruption off the northeast limb flung a bright coronal mass ejection (CME) into space and away from our planet. An impact to our geomagnetic field is unlikely.

A minor (G1) geomagnetic storm watch is in effect beginning on July 5th due to negative polarity coronal hole stream expected to become geoeffective. Sky watchers at high latitudes should be alert for visual aurora later this weekend.
