As initially expected, region 4274 is currently in a safe position for Earth with a strong angular displacement and, despite the high magnitude of the flare that occurred today, the second of the year, it will not be able to have a shock effect on the planet.

Another major explosion was recorded on the Sun this morning. At 11:30 Moscow time, a flare of magnitude X4.05 occurred. The epicenter of the event was once again region 4274, located in the Sun's northern hemisphere.

A very strong planetary-scale magnetic storm, nearly reaching the highest level of G5, is currently being recorded by geomagnetic monitoring equipment as the first of three plasma clouds expected to approach Earth today, amid the extreme increase in flare activity in recent days, approaches Earth. The current event level is G4.66, just one-third short of the highest level.

We publish the results of modeling the plasma motion in today's mass ejection

Spacecraft positioned on the Sun-Earth line, 1.5 million kilometers from the planet, have just been struck by a cloud of high-speed protons ejected from the flare's core. The solar particles are clearly visible in incoming images.

A solar flare of magnitude X5.16 was recorded. It peaked at 1:04 PM Moscow time. In terms of radiation flux, the event is 3-5 times greater than all flares this year. In terms of energy, it is estimated to be 10-20 times greater.

The results of repeated calculations confirm the arrival of two solar plasma ejections from the high-level solar flares that occurred on November 9 and 10 to Earth today, at the junction of November 11-12.

The velocity of the new plasma ejection, measured near the Sun, is likely at least 1,200 km/s, almost twice the velocity of yesterday's event (720 km/s). This means that the gas cloud ejected today will overtake the plasma ejection from yesterday's X1.79 flare, which is currently spreading through space, and they will arrive at Earth together—presumably, as before, around the junction of November 11th and 12th, meaning perhaps as early as tomorrow evening.

A repeat solar flare of the highest magnitude X was recorded in the same solar region, 4274. Maximum radiation was recorded at 12:19 Moscow time. The measured magnitude at the peak was X1.21.

The video shows the first early data from coronagraphs (instruments that observe the circumsolar region). In these images, the ejection is recorded as an expanding cloud of gas flying toward the observer. Based on the images, the ejection is frontal, extending along the Sun-Earth line with a positional offset of about 20 degrees toward the solar system's north pole.
