Magnificent! The depression named Zylan is circulating in the North Sea. It will propel cold air towards France tomorrow. As it passed, winds reached 156 km/h this morning on the Scottish mountains with a felt temperature of -11
Sun news September 10: Storms and filaments
September 10, 2024,
Snip of a detailed analysis of the projected Sun's activities today
Today’s top story: Sun activity has been
moderate in the past day (
11 UTC yesterday to 11 UTC today), with
three M flares. And we’re having fun watching
filaments on the sun’s disk – glowing ropes of solar material and magnetic fields, arcing up from the sun’s visible surface – as we wait today for possible
geomagnetic storms at Earth. The sun’s disk is covered with filaments now, which could bring some eruptions. We also see prominences – the same thing as filaments, but seen on the sun’s limb (edge) – extending into space from the sun’s north and south poles. Meanwhile, a coronal mass ejection (
CME) that left the sun on September 8 is expected at Earth today. This anticipated arrival should bring geomagnetic storms at the level of
G1 to G2 (mild to moderate). Depending on when the CME arrives – and which part of Earth is experiencing darkness at that time – you might get auroras. Get your aurora watching gear ready, and stay tuned.
Last 24 hours: Solar activity is
moderate. In the last 24 hours the sun produced nine flares, three M and six C flares. The largest was an M3.4 at 17:08 UTC on September 9 from active region AR3814. The blast caused an
R1 (minor)
radio blackout affecting an area over the Caribbean Sea off the north coast of Colombia.
The list of M flares is:
• M1.0 at 12:17 UTC on September 9 from AR3811. R1 (minor) radio blackout over Ghana.
• M3.4 at 17:08 UTC on September 9 from AR3814. R1 (minor) radio blackout over the Caribbean Sea off the north coast of Colombia.
• M1.2 at 0:16 UTC on September 10 from AR3814. R1 (minor) radio blackout over the Pacific Ocean.
Only sunspot region AR3814 kept its
beta-gamma magnetic complexity. The remaining labeled active regions show simpler alpha and mostly beta configurations. The sun has nine sunspot regions on its Earth-facing side. We welcomed a newcomer, AR3822. It emerged in the northeast quadrant east of AR3814. Two large
coronal holes also emerged on the Earth-facing side of our star, one in the northeast quadrant and the second in the southeast.
Next 24 hours: The chance for
C flares is 99%. The chance for M flares is 55%. The chance for
X flares is 15%.
Next expected CME: No Earth-directed coronal mass ejections (
CMEs) were observed in available coronagraph imagery.
Current geomagnetic activity: Earth’s magnetic field is quiet at the time of this writing (
11 UTC on September 10). The arrival of a coronal mass ejection (CME) that occurred from a
filament eruption on September 8 might bring
G1-G2 (minor-moderate)
geomagnetic storm conditions anticipated for later today. This combined with high-speed
solar wind from a
coronal hole might create conditions for auroral displays at northern latitudes, perhaps as far south as the northern U.S. states of New York, Washington and Wisconsin. Alert for aurora chasers. Clear skies to you!
