Pair of C-Flares
October 16, 2020 @ 15:30 UTC

C3.5 Solar Flare (SDO/AIA)

A pair of C-Flares were observed within the past few hours off the southwest limb. The latest was a minor C3.5 at 15:11 UTC (Oct 16). After further examination, the activity looks to be centered around a new plage that was in formation just before rotating off the limb. They did not originate around plage region 2775, still in view in the southwest quadrant. Because this activity is taking place around a region not facing our planet, there will be no impacts expected. Image by SDO/HMI.

Solar Update (UPDATED)
October 14, 2020 @ 00:30 UTC

Possible Active Region (SDO/AIA)

Solar activity continues at very low levels. AR 2775 decayed to a spotless plage and is non threatening.

A new region that began forming within the past few days while on the farside of the Sun is now turning into view off the east limb. We will find out during the next day or so if the region is continuing in a growth phase and if any spots will become visible. Attached image by the Solar Dynamics Observatory (SDO) using the 171 angstroms channel.

UPDATE: The new region was assigned AR 2776 on Wednesday. A few spots are currently visible and appears to be expanding somewhat. So far only minor B-Flares have been detected.

Visible Solar Disk (SDO/HMI)

Solar activity remains at very low levels heading into Sunday. AR 2775 did show minor flux emergence on Saturday, but was otherwise stable. Elsewhere, AR 2774 also in the southern hemisphere nearly decayed to plage status.

The geomagnetic field remained at quiet levels and is expected to continue in this state for the next few days. No Earth directed coronal mass ejections were observed in available coronagraph imagery.

Solar Update / New Sunspots

New Sunspots (SDO/HMI)

A pair of sunspots in formation are now visible in the southern hemisphere. They have yet to be assigned official active region status, however that could happen on Friday morning should they stick around long enough. So far they are both magnetically simple and not a threat for noteworthy solar flares. Something to keep an eye on over the next day or so. Image by SDO/HMI.

UPDATE: These new regions were officially assigned AR 2774 and AR 2775. This breaks the spotless streak of nearly two weeks.

Geomagnetic Disturbance
October 5, 2020 @ 21:20 UTC

Auroral Oval

The Bz component of the interplanetary magnetic field (IMF) carried past Earth via the solar wind is currently pointing south. This is helping to disturb our geomagnetic field (Kp4). High latitude sky watchers should be alert for visible aurora once dark outside.

ALERT: Geomagnetic K-index of 4
Threshold Reached: 2020 Oct 05 1949 UTC
Synoptic Period: 1800-2100 UTC
Active Warning: Yes

Solar Update

Visible Solar Disk.

The visible disk remains void of sunspots on Friday (Oct 2). A few minor plage regions belonging to Cycle 25 have popped up across the disk, but have so far failed to expand further. Solar activity should remain at very low levels.

Geomagnetic activity continues to trend towards quieter levels as the coronal hole stream wanes. Visible aurora should be confined to the polar zones this weekend.
