Big Sunspot / Farsided Eruption

AR 2785 and 2786 (Nov 24) SDO/HMI

AR 2786

Large sunspot region 2786 along with smaller region 2785 continue to turn into view on Tuesday. 2786 is quite large, the dark core being slightly larger than the planet Earth. Despite its size, the region is not magnetically complex enough to be a threat for large solar flares. Things can change so stay tuned!

UPDATE: With the help of big AR 2786, the solar flux has reached 100 on Tuesday! This is a first for Solar Cycle 25.

Farsided Eruption

Old region 2781 currently transiting the farside of the Sun produced a fair sized solar flare that is associated with a fast moving coronal mass ejection (CME). Because this happened on the opposite side of the Sun relative to Earth, it will be directed completely away from our planet. Old region 2781 is still about 6 days away from turning back into Earth view. Image by STEREO Ahead.

Sunspots (Nov 22) SDO/HMI

New Sunspots

Good evening. Solar activity was at low levels on Sunday with minor C-Flares observed around newly assigned region 2785, now turning into view off the southeast limb. Another new sunspot is now just making appearance off the limb and we will get a better look over the next 24 hours. Existing region 2783 is now showing some flux emergence within the trailing section and will be monitored. The solar flux index for today is 88. With another region turning into view, along with potential development with 2783, the SFI should climb above 90 on Monday.

Minor Storm Observed

In other news, the coronal hole stream continues to flow past Earth near 600 km/s. Active geomagnetic conditions, possibly reaching minor (G1) storm levels will be possible during the next 24-48 hours. High latitude sky watchers should be alert for visual aurora.

Coronal Holes (Nov 22) SDO/AIA

A solar wind stream flowing from partially Earth facing coronal hole #96 should contribute to minor geomagnetic enhancements during the next 24-48 hours. There will be a lower chance for an isolated period of Minor (G1) storming. Aurora sky watchers should be alert at higher latitudes.

Activity Behind Limb (Nov 20) - SDO/AIA

Despite being a few days away, Solar X-Rays is already picking up some activity from behind the southeast limb on Friday.

A pair of likely active sunspot regions have been seething with activity the past few days and will be turning into view later this weekend. Although much can change, an increase in solar activity is expected. Image below captured by the STEREO Ahead spacecraft on Thursday shows the source regions. Stay tuned for more updates.

Farsided Active Region(s) - STEREO Ahead

Earth facing space weather remains at very low levels. The lone numbered region (AR 2783) remains magnetically stable and non threatening at this time.

A possibly large sunspot group, or perhaps a pair of regions is about 5 days away from the east limb. We will have a better idea during the next few days. Judging by the latest video run by STEREO Ahead, they appear to be fairly active.

Visible Disk (Nov 15) SDO/HMI

With AR 2782 now a spotless plage and AR 2781 about to turn out of view off the southwest limb, we could perhaps see brief period with no visible sunspots. Whatever remains of old regions 2778 and 2779 is expected to turn into view during the next 24-36 hours. Another region trailing behind 2778/2779 appears more likely to have visible spots and is about 48-72 hours away from the east limb. Stay tuned to SolarHam.com for the latest updates.

AR 2782 (Nov 13) (SDO/HMI)

Good day to everybody. Region 2782 continues to turn into a better Earth facing position and looks to have sprouted a few small spots within the central section of the group. For now the region does not appear to be a threat for moderate to strong solar flares.

A minor C2 flare around AR 2782 on Wednesday was associated with a small CME, but it is directed to the east and away from Earth. Little to no impacts should be expected.

New AR 2782 (Nov 11) (SDO/HMI)

With sunspot region 2781 commanding all of the attention the past little while, a new sunspot group (AR 2782) is now turning into view off the southeast limb. So far the region does not appear to be too threatening, but we will get a better look over the next few days. Image by SDO/HMI.

Potential Active Region (Nov 8) (STEREO-A)

Hello again folks. Solar activity remained at low levels during the past 24 hours with only minor flaring observed around AR 2781. The largest flare was a C5.7 at 05:18 UTC.

A potential new active region located high in latitude behind the southeast limb popped up during the past few days and will begin to turn into view beginning on Monday.

AR 2781 (Nov 6) (SDO/HMI)

Large active region 2781 continues to produce occasional C-Flares as it moves across the southeast quadrant. The region gained beta-gamma magnetic status on Friday and will remain a threat for an isolated M-Flare. The next several days will see 2781 in prime position for possible Earth directed eruptions.

In the northeast quadrant, AR 2780 remains small and inactive and is not considered a threat for flares at this time.

A weak coronal hole stream is moving past Earth above 450 km/s and this could generate minor geomagnetic disturbances at very high latitudes. Storming is not in the forecast.

Stay tuned to SolarHam.com for the latest information.

Sunspot Group 2781 Growing
November 5, 2020 @ 01:40 UTC

AR 2781 (Nov 5) (SDO/HMI)

Large active region 2781 is expanding in size and despite being a "monster" sunspot, it only has a beta magnetic configuration for the time being. This could change over the next few days as the region continues to evolve. The region continues to turn into an Earth facing position and future eruptions could potentially be directed towards Earth. The largest flare detected up until this update was a fairly minor C7.3 at 00:22 UTC (Nov 5). Solar Cycle 25 is finally starting to step it up a notch!

Stay tuned to SolarHam.com for the latest space weather news and data.

Big Sunspot (UPDATED)
November 4, 2020 @ 02:15 UTC

Returning Active Region (SDO/HMI)

UPDATE: Active Region 2781 continues to move into view and it is quite large, however mostly stable for the time being. This region is likely capable of producing isolated C-Flares, and with any changes magnetically, perhaps an isolated M-Flare. More updates to follow whenever necessary.


As expected, old region 2777 is turning back into view and it expanded in size while transiting the farside of the Sun. A few dark cores are now becoming visible and this region should be reassigned AR 2781 during the next 12 hours. So far the solar X-Rays are stable in very minor B-Class territory. Although we do not have a good look yet, the sunspot group is likely a threat for isolated C-Class solar flares. Image by SDO/HMI.

Elsewhere, a small sunspot located in the northeast quadrant was assigned AR 2780, but is struggling to remain visible as we head into Tuesday.

Stay tuned to SolarHam.com as new sunspots associated with Solar Cycle 25 are appearing more frequently.

Solar Update / Active Region Approaching
November 1, 2020 @ 23:10 UTC

Region Approaching SE Limb (SDO/HMI)

Solar activity was at low levels on Sunday with a couple of low level C-Flares detected off the southwest limb in the vicinity of departing region 2778. Both regions 2778 and 2779 who were in a state of decay are now out of direct Earth view and will not be a threat for Earth directed eruptions.

Old region 2777 is about a day away from turning back into view off the southeast limb. Imagery courtesy of STEREO Ahead suggests that the region is possibly still active and producing perhaps minor C-Flares. We will get a better look during the next 48 hours.
