  2. My estimation (based on the position of #AR4366) is that it will be Earth-facing in 4-5 days...

    "Sunspot Watch
    January 31, 2026 @ 04:15 UTC
    Newly assigned sunspot region 4366 continues to gradually develop as it turns into view in the northeast quadrant. It is currently producing minor C-Class flares and it is likely now a threat for a moderate M-Flare. Something to keep an eye on this weekend. Image by SDO/HMI.

    Growing Flare Threat
    January 31, 2026 @ 14:50 UTC
    AR 4366 continued to expand over the past 12 hours in both size and magnetic complexity. The region has a Beta-Delta magnetic configuration and is producing frequent mid level minor C-Flares. A moderate M-Flare will remain possible on Saturday.

    M6.6 Solar Flare
    February 1, 2026 @ 10:40 UTC
    Solar activity increases even further with an M6.6 solar flare peaking at 10:02 UTC (Feb 1). The source, AR 4366, is magnetically complex and is now a threat for an isolated X-Flare. Image below by SDO/AIA.

    High Solar Activity
    February 1, 2026 @ 16:50 UTC (UPDATED)
    What a difference a few days make on the Sun. Active sunspot region 4366 turned into a firecracker on Sunday with at least fifteen M-Class solar flares and one X-Flare (so far). Despite the brightness of these events, the mechanics have so far failed to launch any noteworthy coronal mass ejections into space and towards our planet. That could change over the next few days as the region continues to develop and currently sports a Beta-Gamma-Delta magnetic configuration. More solar flares including another X-Flare will remain possible.

    [And today...]

    Impulsive X8.1 Solar Flare
    February 2, 2026 @ 00:10 UTC
    An impulsive X8.1 solar flare was just detected peaking at 23:57 UTC (Feb 1). This is the second strongest flare in terms of peak X-Ray flux of the current solar cycle. Although a bright flare, new imagery suggests that if a CME is associated, it will likely be fairly mild. Stay tuned to SolarHam where you will get the most up to date and accurate information regarding this space weather event."

    Largest #SolarFlare Of #SolarCycle25 Observed

    May 14, 2024 @ 17:05 UTC (UPDATED)

    "The largest solar flare of the current solar cycle 25, and largest since 2017 was just observed around deparing #AR3664 off the west limb. The #X8.7 event peaked at 16:51 UTC (May 14) causing a strong R3 level radio blackout directly over North America. More to follow.

    "And Then...

    "An eruption in the vicinity of newly assigned #AR3682 measuring M4.4 was observed at 17:38 UTC (May 14). This event looks to be eruptive, meaning a #CME will be produced.

    "Solar Cycle 25 just kicked it up a notch!"

  5. Enormous '#Sunspot archipelago' 15 times wider than Earth could soon bombard us with #SolarFlares

    Story by Harry Baker, November 21, 2023

    "One of the largest and most densely populated sunspot regions seen in more than a decade has appeared on the sun's nearside to Earth — and has begun to unleash a barrage of solar storms that are shaking up our home star's surface in a big way. The sunspots' emergence could make it an interesting few weeks for Earth, which will soon be in the firing line of these eruptive dark patches.

    "The first sunspot group, named #AR3490, rotated onto the sun's nearside on Nov. 18 over the star's northeastern shoulder. The dark patch was quickly followed by another sunspot group, #AR3491, which trailed in its wake, #Spaceweather.com reported.

    "Scientists already knew that the sunspot groups were on their way because they had been tracking '#HelioseismicTremors," or ripples in the sun's surface, from the area. The sunspot region is 'so large, it is affecting the way the whole sun vibrates,' Spaceweather.com representatives wrote.

    "Since emerging, the sunspot groups have split up and birthed new dark patches, including #AR3492, #AR3495, #AR3496 and #AR3497, which has created a 'solar archipelago of sunspots,' astronomy news site EarthSky reported.

    "In total, the massive collection of sunspots spans around 125,000 miles (200,000 kilometers) across, which is more than 15 times wider than Earth, according to Spaceweather.com.

    "The sunspots have already spat out at least 16 C-class and 3 M-class solar flares — which are the third and second strongest flare classes, respectively — in the last 4 days, according to SpaceWeatherLive.com. And experts are warning that there could be many more of these flares in the next few weeks, as well as potentially #XClass flares, the strongest type of solar flare.

    "The impending flares may also birth coronal mass ejections (#CMEs), or enormous blobs of charged solar particles, that could slam into Earth and trigger strong geomagnetic storms, which could cause radio blackouts and spark vibrant aurora displays.

    "Astronomers have also spotted several large loops of plasma, known as #SolarProminences, growing above some of the sunspots in the group. The largest loops tower more than 40,000 miles (64,000 km) above the surface, according to EarthSky, and could snap off and fling into space at any moment, temporarily leaving behind enormous 'canyons of fire' in the sun's surface.

    "At least three sunspot groups have also emerged on the sun's southern hemisphere in the last few days.

    "The sunspots' emergence is the latest sign that the sun is fast approaching the explosive peak in its roughly 11-year solar cycle, known as the solar maximum, which scientists now predict will begin next year.

    "During solar maximum, sunspots become much more frequent and increase in size as the sun's magnetic fields get tangled up, allowing the dark patches to grow more easily.

    "The latest dark patches make up 'probably the biggest sunspot region I've seen so far from [the current] solar cycle,' Chris Wicklund, a meteorologist and aurora photographer, wrote on X (formerly known as Twitter). 'The next 14 days could be very interesting,' he added."

  6. Finally a relatively quiet weekend conditions on the #amateurradio #hamradio bands. 7 #sunspot regions with less than triple digit #sunspots. Looks like #coronalholes have a slight potential of producing a minor #geomagneticstorm. #spaceweather #solarcycle25
