SOLAR CYCLE 25 ACTIVITY REPORT MARCH 04_2024

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C3 event observed at 1729 UTC

The total number of sunspots has decreased to 90 of which 21 of them are grouped into 8 active regions as follows: AR3591, AR3592,
AR3595, AR3596, AR3598, AR3599, AR3600 & new region AR3601

NOAA's solar flare forecast was updated for the next 24 hours: 85% chance of C flares, 25% chance of M flares and 1% chance of X flares. AR3595 has a beta-gamma magnetic field that harbors energy for M-class flares. All other regions have a stable magnetic field.

● Auroral Activity

The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 481 km/s (Elevated speed) at 0528 UTC Total IMF reached 19 nT at 11: 08 UTC (strong impact to the Earth's magnetic field)​

A shock in the solar wind was observed around 08:47 UTC this morning. The shock is possibly related to partial halo coronal mass ejection launched February 28. Taking into account the current solar wind and IMF conditions, geomagnetic conditions are expected to rise to storm levels within the next couple of hours. SpaceWeatherlive on X​

THE CME HAS ARRIVED: An overdue CME struck Earth's magnetic field on March 3rd (0930 UT). The impact sparked a G2-class geomagnetic storm with bright auroras around the Arctic Circle. SpaceWeather.com​

On March 03 Active geomagnetic conditions (kp4) were reached at 13:30 UTC. Minor G1 geomagnetic storm (Kp5) threshold reached at 14:24 UTC Moderate G2 geomagnetic storm (Kp6) threshold reached at 20:59 UTC SpaceWeather.com​

SUBSIDING STORM: A geomagnetic storm triggered by today's stronger-than-expected CME impact is subsiding now. Although storm levels are trending below G1 (Minor), high-latitude sky watchers should remain alert for auroras. The storm could re-energize itself as Earth passes through the CME's turbulent wake.

● Current Conditions at 04:42 UTC on March 04

Geomagnetic activity is at index Kp4 (active) after a brief period of a G2 geomagnetic storm. The CME mass hit the magnetic field harder than expected. The solar wind reached elevated velocities, however, at the time of this report the velocity remains at normal levels above 350 km/s. Although conditions for auroral observations at high latitudes are moderate, there were reports of auroras during the geomagnetic storm. The interplanetary magnetic field (IMF) has a strong impact on the Earth's magnetic field, reaching 13 nT. The last recorded solar flare was a C2 at 03:16 UTC.

SOLAR CYCLE 25 ACTIVITY REPORT MARCH 11_2024

Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a M7.4 event observed at 12:13 UTC from Region 3599 (S13W42) The flare generated a Moderate R2 radio blackout over Africa​

The total number of sunspots has increased to 77 of which 28 of them are grouped into 6 active regions as follows: AR3599, AR3600 AR3602, AR3603, AR3604 & AR3605

NOAA has updated its forecast for the next 24 hours: 80% chance of C flares, 25% chance of M flares and 5% chance of X flares. AR3599 has a beta-gamma-delta-class magneticfield that harborsenergyforX-classflares. This region is composed now of 15 sunspots occupying an area of 210 MH. The active region is currently facing Earth and will remain a threat for M or X flares
​

SNEAKY-DANGEROUS SUNSPOT: Sunspot AR3599 doesn't look dangerous. It is relatively small and has a simple, bipolar morphology--two factors which usually add up to "harmless." Yet today (March 10 @ 1213 UT), it produced a strong M7-class solar flare:​

​

Extreme ultraviolet radiation radiation from the flare ionized the top of Earth's atmosphere, causing a strong shortwave radio blackout over Africa and the South Atlantic: map. Mariners and ham radio operators may have noticed loss of signal for as much as 30 minutes after the flare.​

So far it does not appear that the flare hurled a significant CME toward Earth. SpaceWeather.com​

THE DAY THE SUN BROUGHT DARKNESS: Forty-five years ago today, the greatest solar storm of the Space Age engulfed our planet. A powerful coronal mass ejection (CME) hit Earth early on March 13, 1989, and within 90 seconds, the entire Hydro-Québec power grid failed. During the 9-hour blackout that followed, millions of Quebecois found themselves with no light or heat. Happy Anniversary? Maybe. We're better prepared today than ever before. SpaceWeather.com​

QUIET WITH A SLIGHT CHANCE OF STORMS:
Today, geomagnetic activity is low and the forecast calls for no bright auroras. However, a change may be in the offing. NOAA forecasters say that a CME might graze Earth's magnetic field on March 14th. A minor G1-class geomagnetic storm could result from the low-probability impact. SpaceWeather.com​

PROTONS ARE RAINING DOWN ON EARTH:
Solar protons are raining down on Earth's upper atmosphere today following a March 14th explosion from departing sunspot AR3599. This is causing a polar cap absorption event. Shortwave radio transmissions inside the Arctic Circle are being absorbed by the ionizing effect of the protons: realtime blackout map. SpaceWeather.com​

​

MINOR RADIATION STORM IN PROGRESS: The GOES 10 MeV radiation threshold has been passed which puts us in an S1 radiation storm. The main effect is to radio communications in the polar regions and may divert some transpolar flights.

SOLAR CYCLE 25 ACTIVITY REPORT MARCH 17_2024

Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M3 event observed at 1635 UTC from a unnumbered sunspot located on the west limb. The flare generated a Minor R1 radio blackout over Central & South America. Note that the polar regions were already suffering significant interference from the radiation storm of yesterday​

https://twitter.com/x/status/1769073752002756844

A second M flare M1.2 occurred at 21:55 UTC from the same region. The flare generated a Minor R1 radio blackout over West Pacific Ocean​

SOMETHING FLARE-Y THIS WAY COMES: Today, March 16th (1635 UT), Earth-orbiting satellites detected an impulsive M3.5-class solar flare. The source was just behind the sun's southeastern limb:​

​

The flare was partially eclipsed by the edge of the sun. That means it was stronger than it appeared, potentially even X-class. The underlying sunspot could rotate onto the Earthside of the sun before the weekend is done. SpaceWeather.com​

The total number of sunspots has increased to 67 of which 17 of them are grouped into 5 active regions as follows: AR3607, AR3610, AR3611, AR3612 & new region AR3613​

NOAA has updated its forecas for the next 24 hours: 75% chance of C flares, 5% chance of M flares and 1% chance of X flares. All regions have stable magnetic fields.​

● Auroral Activity

The geomagnetic field has been at quiet levels for the past 24 hours. On March 16 Solar wind speed reached a peak of 516 km/s (Moderately High speed) at 05:24 UTC No significant record on IMF​

Aurora Oval Bz: -0.98 nT South


● Current Conditions at 04:26 UTC on March 17

Geomagnetic activity is at index Kp0 (quiet) and the S1 radiation storm continues.

Over the last few days, the sun erupted in prominences, filaments, coronal mass ejections (CMEs) and now solar energetic particles, aka high energy protons. The CME yesterday from sunspot region AR3599 was not Earth-directed but accelerated protons to near lightspeed. The particles have charge, which means they spiral around (and follow) magnetic fields. That’s why – even though the CME wasn’t aimed at us – the protons headed toward us and are still showering Earth. The sun’s magnetic field curves out from the west side of the sun back toward Earth, so the fast protons follow the magnetic field (like a magnetic particle highway) and buffet our planet. EarthSky.org

The solar wind speed has reached a normal speed of 357 km/s. The interplanetary magnetic field (IMF) has no significant impact on the Earth's magnetic field. The last recorded solar flare was a C6 0359 UTC. On March 17, Solar activity is expected to be low. The geomagnetic field is expected to be at quiet to unsettled levels.​
