Minor G1-class geomagnetic storms are possible on Jan. 19th when a CME is expected to graze Earth’s magnetic field. The CME was hurled into space on Jan. 14th by a dramatic twisting eruption in the magnetic canopy of sunspot AR3182. High latitude sky watchers should be alert for auroras when the CME arrives.

ANOTHER X-CLASS SOLAR FLARE: Earth-orbiting satellites detected another X-class solar flare today–the second in less than a week and a possible harbinger of more to come. There are now two large, unstable sunspots capable of producing these strong explosions, and both are turning toward Earth.

X-CLASS SOLAR FLARE: A large and potentially dangerous sunspot is turning toward Earth. This morning (Jan. 6th at 0057 UT) it unleashed an X-class solar flare and caused a shortwave radio blackout over the South Pacific Ocean. Given the size and apparent complexity of the active region, there’s a good chance the explosions will continue in the days ahead.

SIGNIFICANT FARSIDE EXPLOSION: A powerful explosion rocked the farside of the sun yesterday, hurling a bright CME over the edge of the solar disk. It may have been an X-class event. Helioseismic echoes suggest that the source of the blast is just behind the sun’s southeastern limb and could turn to face Earth later this week.

A new, apparently large sunspot group is emerging over the sun’s eastern limb, right here. Even before it rotated into view, the sunspot produced multiple M-class flares partially eclipsed by the edge of the sun. Even stronger flares may be in the offing as the sunspot turns fully toward Earth.

SOLAR ACTIVITY INTENSIFIES: After months of relative calm, the sun burst back into life yesterday with a remarkable series of M-class solar flares. The fusillade ionized the top of Earth’s atmosphere and caused a rolling global shortwave radio blackout. If current trends continue, an X-flare may be in the offing, with at least one dangerous sunspot directly facing Earth.

Today, there are nine distinct sunspot groups crossing the face of the sun–the greatest number so far during young Solar Cycle 25. This would seem to boost the odds of a solar flare. However, all nine sunspots have relatively stable magnetic fields disinclined to explode. Solar activity may remain low despite the high sunspot count.

A new sunspot (AR3153) is rotating over the sun’s southeastern limb, and it is a big one. NASA’s Solar Dynamics Observatory (SDO) is seeing at least two dark cores significantly wider than Earth. The entire group is inset in this magnetic map of the sun’s surface taken by SDO during the early hours of Dec. 2nd.

Possible CME Impact.
A shock wave in the solar wind hit Earth’s magnetic field today, Nov. 25th, at approximately 0230 UT. It might have been the belated arrival of a CME that left the sun on Nov. 19th, hurled in our direction by an erupting filament of magnetism. So far the weak impact has not caused a geomagnetic storm.

GEOMAGNETIC STORM WATCH: NOAA forecasters say there is a chance of G1-class geomagnetic storms on Nov. 20th when a high-speed stream of solar wind is expected to hit Earth. The gaseous material is flowing from a large southern hole in the sun’s atmosphere. Arctic sky watchers should be alert for auroras.
