June 12 update: Sun activity low after slight increase
Today’s sun news: AR3030 rotated further into view. A small new region, AR3031, developed in the southeast. Overall sun activity is back to low.
Last 24 hours: Sun activity has decreased with 5 flares from AR3030, of which four were C-class flares and one B-class.
Next 24 hours: The forecast today is for a 60% chance for C flares, 10% for M flares, and 1% for X flares.
Next expected CME: There are no Earth-directed CMEs. Further analysis shows no inbound CME.
Current geomagnetic activity: Quiet.
A WEEK OF SUN: The sun has been relatively quiet from June 2 – 10, slightly more than a week. Notable was an M1.2 but mostly just C and B flares. Minor non-Earth-directed CMEs and many dancing filaments. When will things pick back up? ????? pic.twitter.com/EyzpVV3HeN

June 11 update: CME coming our way
Today’s sun news: A filament around the visible center of the sun (south of solar equator, west of central meridian) blasted out a minor CME on June 10, 2022. It is Earth-directed, expected by June 13. Newly labeled sunspot region AR3030 has increased in both size and magnetic complexity since yesterday. AR3030 produced an M1.2-class flare yesterday (June 10, 2022) at around 10:30 UTC. Before that, the most recent M-flare – a stronger class of flare than B- or C-flares – was on May 25. The June 10 M1.2-flare provoked a minor R1 radio blackout over Africa. A coronal hole appeared north of the solar equator, east of the central meridian. Finally, on the sun’s far side, there were massive blasts yesterday from AR3016 and AR3018. Both are still behind the sun’s southeast limb (edge).
A faint front was seen propagating from SOHO/C3 imagery and may be associated with an eruption that occurred from around S30E10 last night–this CME may have an Earth-directed component but generally won’t be expected to provide any significant geomagnetic activity. pic.twitter.com/wP0zxMe5UM

June 10 update: New sunspot region AR3030
The sunspot region labeled AR3030 has now come around from the sun’s far side to the Earth-facing side of the sun. Is it the return of a former active region, AR3014, the biggest of Solar Cycle 25 so far? We last saw AR3014 on May 27, 2022, as the sun’s rotation was carrying it out of view. It was in the company of another, smaller region, AR3017. Now it’s uncertain whether we’re seeing AR3014 again, possibly regrouped with AR3017.
WAKIN’ UP! Activity has begun to pick up thanks to the new region on the northeast (left) limb of the sun. Many C flares then BOOM! An M1.2 around 10:30 UTC. Produced a radio blackout over Africa. How much will it pick up? ???? pic.twitter.com/KSMr1QnO6E

June 9 update: A spotless sun yesterday
Within the past 24 hours, the sun had its first spotless day (a partial day) in 2022. A spotless sun is a fairly rare occurrence on the approach to solar maximum, the highest point in the current solar cycle (Solar Cycle 25), expected around the middle of this decade. After being spotless, a sunspot group with about 20 small spots emerged in a circle, just east of sun center in the sun’s southern hemisphere. This region is now labeled AR3029. In the meantime, the STEREO spacecraft also sees a bright region just over the northeast limb (edge) of the sun.
NEW SUNSPOT REGION EMERGING RAPIDLY: A sunspot group with about 20 small spots has emerged just east of sun center in the southern hemisphere. Oddly they have emerged in a circle. Let’s see if it develops further at this break-neck speed over the next few days. pic.twitter.com/x686GkF9Xb

June 8 update: Sunspot regions rotating into view
The solar disk is almost spotless, with sun activity at its lowest levels in weeks. The individual sunspots in the two Earth-facing sunspot regions are barely visible. These regions are currently decaying and may soon be completely gone. But incoming regions on the east limb (edge) – now rotating into view – look promising. The one in the northeast (upper left of image above) could be related to two previous active sunspot regions – AR3014 and AR3017 – which rotated out of view 10 days or so ago. And the one in the southeast (lower left of image above) could be related to AR3018, which also left the Earth-facing part of the sun some days back.
June 7 update: Lots of filaments and prominences
The sun is still quiet. Its disk appears almost spotless, with just four tiny active regions. But this is just the sun taking a breather. The overall sunspot number over the past month is still at an all-time high for this point in the current sunspot cycle (Solar Cycle 25). The current level of sunspots is far surpassing NOAA’s official predictions for this point in the cycle. For more about this, see the tweet below. And, while we wait for more sunspots to form and rotate into view, the sun is covered with prominences and filaments. The potential eruption of these structures provides a possible source for CMEs, with the potential to impact Earth and cause future auroral displays.

June 6 update: CME arrived today
The CME glancing blow from the June 1 filament eruption didn’t strike yesterday as expected. But it’s here now. It brushed Earth’s magnetic field at approximately 10 UTC today (6 a.m. EDT on June 6, 2022). What does it mean for aurora-watchers? Probably nothing, as no geomagnetic storm has occurred. Meanwhile, overall activity on the sun itself remains very low.

A week of sun activity: May 19 to 26
A WEEK OF SUN! A four-panel look at SDO 1700, 304, 171, and 193-angstrom wavelengths from May 19 through May 26. Filament eruptions, coronal holes, a few flares of note, and more. ???? pic.twitter.com/HRiEUfcLmC

Bottom line: June 12, 2022: Sun activity back to low. A small new region developed in the southeast but overall things are quiet. Further study shows no expected CMEs.
