AR 3664 at the Sun's Edge Image Credit & Copyright: Sebastian Voltmer

Explanation: What did the monster active region that created the recent auroras look like when at the Sun's edge? There, AR 3664 better showed its 3D structure. Pictured, a large multi-pronged solar prominence was captured extending from chaotic sunspot region AR 3664 out into space, just one example of the particle clouds ejected from this violent solar region. The Earth could easily fit under this long-extended prominence. The featured image was captured two days ago from this constantly changing region. Yesterday, the strongest solar flare in years was expelled (not shown), a blast classified in the upper X-class. Ultraviolet light from that flare quickly hit the Earth's atmosphere and caused shortwave radio blackouts across both North and South America. Although now rotated to be facing slightly away from the Earth, particles from AR 3664 and subsequent coronal mass ejections (CMEs) might still follow curved magnetic field lines across the inner Solar System and create more Earthly auroras.

Aurora Banks Peninsula

Image Credit & Copyright: Kavan Chay

Explanation: This well-composed composite panoramic view looks due south from Banks Peninsula near Christchurch on New Zealand's South Island. The base of a tower-like rocky sea stack is awash in the foreground, with stars of the Southern Cross at the top of the frame and planet Earth's south celestial pole near center. Still, captured on May 11, vibrant aurora australis dominate the starry southern sea and skyscape. The shimmering southern lights were part of extensive auroral displays that entertained skywatchers in northern and southern hemispheres around planet Earth, caused by intense geomagnetic storms. The extreme spaceweather was triggered by the impact of coronal mass ejections launched from powerful solar active region AR 3664.

Solar X Flare as Famous Active Region Returns

Video Credit: NASA, Solar Dynamics Observatory

Explanation: It's back. The famous active region on the Sun that created auroras visible around the Earth earlier this month has survived its rotation around the far side of the Sun -- and returned. Yesterday, as it was beginning to reappear on the Earth-facing side, the region formerly labeled AR 3664 threw another major solar flare, again in the highest-energy X-class range. The featured video shows the emerging active region on the lower left, as it was captured by NASA's Earth-orbiting Solar Dynamics Observatory yesterday in ultraviolet light. The video is a time-lapse of the entire Sun rotating over 24 hours. Watch the lower-left region carefully at about the 2-second mark to see the powerful flare burst out. The energetic particles from that flare and associated CME are not expected to directly impact the Earth and trigger impressive auroras, but scientists will keep a close watch on this unusually active region over the next two weeks, as it faces the Earth, to see what develops.

Ignore the madhat notes

:Product: Forecast Discussion :Issued: 2024 May 29 0030 UTC

Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center

# Solar Activity

.24 hr Summary… Solar activity was at low levels with numerous C-class flares. The main culprits of this activity were ARs 3691 (N27E20, Ekc/beta-gamma-delta) and 3697 (S18E69, Eho/beta-gamma). The largest flare of the period originated from AR3697 as a C8.9 at 28/1841 UTC. Region 3697 has yet to fully rotate into view, making proper classification precarious at best while 3691 was little changed. Region 3692 (S08W24, Cro/beta) exhibited decay in its trailing spots, and 3693 (N05E07, Dao/beta) continued to increase the separation between its leading and trailing groups. The remaining active regions were relatively stable and quiet. An asymmetric halo CME, first observed in LASCO coronagraph imagery at approximately 28/0524 UTC, was deemed to be a far-sided event, thus no Earth-directed CMEs were observed in available coronagraph imagery.

.Forecast… Solar activity will likely reach moderate levels with a few M-class flares (R1-2/Minor-Moderate Radio Blackouts) while maintaining a chance for isolated X-class flares (R3/Strong Radio Blackouts) through 31 May.

Energetic Particle

.24 hr Summary… The greater than 2 MeV electron flux was normal to moderate and the greater than 10 MeV proton flux remained at background values.

.Forecast… The greater than 2 MeV electron flux is expected to remain at normal to moderate levels through 30 May. There is a slight chance for a greater than 10 MeV proton event exceeding the S1 (Minor) threshold through 31 May primarily due to the flare potential of Regions 3691 and 3697.

Solar Wind

.24 hr Summary… Solar wind parameters were at or near nominal levels. Solar wind speed averaged below 350 km/s. Total field ranged from 1-7 nT while the Bz component was between +5/-4 nT. Phi became predominantly positive after approximately 28/0607 UTC.

.Forecast… An enhancement in the solar wind environment due to indirect shock arrival from the 27 May X2.8 flare event may arrive by late 29 May. The solar wind environment is expected to return to ambient-like levels over the course of 30 May and remain there through 31 May.

Geospace

.24 hr Summary… The geomagnetic field was at quiet levels.

.Forecast… Isolated active levels, with a chance for G1 (Minor) storming, are expected on 29 May with any shock arrival from the 27 May CME. Quiet to unsettled conditions are expected on 30 May as any lingering shock effects wane. Mostly quiet conditions are anticipated to prevail 31 May.

Forecast of Solar and Geomagnetic Activity 27 May - 22 June 2024

Solar activity is expected to be at a chance for moderate (R1-R2 / Minor-Moderate) levels due to the return of previous active region 3664 (S17, L=347).

There will be a slight chance of S1 (Minor) solar radiation storms from 28 May through 09 Jun upon the return of old region 3664.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at low to moderate levels.

Geomagnetic field activity is expected to be at unsettled to active levels on 27-28 May and 08-12 Jun due to the influence of positive polarity CH HSSs. Mostly quiet levels are expected on 29-31 May, 01-07 Jun and 13-22 Jun.

Esta vista panorâmica composta bem composta olha para o sul da Península de Banks, perto de Christchurch, na Ilha Sul da Nova Zelândia. A base de uma pilha rochosa em forma de torre está inundada em primeiro plano, com as estrelas do Cruzeiro do Sul no topo da moldura e o pólo celeste sul do planeta Terra perto do centro. Ainda assim, capturada em 11 de maio, a vibrante aurora austral domina o mar estrelado do sul e a paisagem celeste. As cintilantes luzes do sul faziam parte de extensas exibições aurorais que entretinham os observadores do céu nos hemisférios norte e sul do planeta Terra, causadas por intensas tempestades geomagnéticas. O clima espacial extremo foi desencadeado pelo impacto das ejeções de massa coronal lançadas pela poderosa região solar ativa AR 3664.

AR 3664: Giant Sunspot Group Image Credit & Copyright: Franco Fantasia & Guiseppe Conzo (Gruppo Astrofili Palidoro)

Explanation: Right now, one of the largest sunspot groups in recent history is crossing the Sun. Active Region 3664 is not only big -- it's violent, throwing off clouds of particles into the Solar System. Some of these CMEs are already impacting the Earth, and others might follow. At the extreme, these solar storms could cause some Earth-orbiting satellites to malfunction, the Earth's atmosphere to slightly distort, and electrical power grids to surge. When impacting Earth's upper atmosphere, these particles can produce beautiful auroras, with some auroras already being reported unusually far south. Pictured here, AR3664 and its dark sunspots were captured yesterday in visible light from Rome, Italy. The AR3664 sunspot group is so large that it is visible just with glasses designed to view last month's total solar eclipse. This weekend, skygazing enthusiasts will be keenly watching the night skies all over the globe for bright and unusual auroras.
