After a time of calm in the sun of the sun, this week changed with the strongest solar flacker from 2025 and coronal masses that could trigger northern lights in the coming nights.
What happened in the sun
On May 13th and 14th, NASA discovered the solar flares X1.2 and X2.7, which so far the strongest since 28 and 2025. Solar torches are unpredictable and intensive energy and electromagnetic radiation from the sun surface. X-Class describes the most intense torches, while according to NASA, the number provides more information about its strength. On May 14th there were also two slightly weaker solar torches of the M-Class with M5.3 and M4.7.
Most of the activity comes from a new solar stain called 4087, which according to Spaceweather.com has appeared on the left side of the sun.
Coronal masses and Auroras
Solar torches do not cause Auroras, but short -wave radio -blackouts. At the speed of light, the radiation from a solar flare lasts to reach the earth. After the X-Class solar torches, short power outages were reported all over the world.
It is what can follow in the course of a sunlight in which Aurora hunters are interested. Solar -flares often trigger what solar physicists call coronal mass emissions, in which a cloud of overloaded particles leaves the sun surface and flooded over the solar system, but at a much slower speed over the radiation from a solar factor. After the solar flare on May 14th, a CME was discovered, but it travels towards Mars, not on earth.

Northern lights prediction
The Aurora borealis is known to be difficult to predict. This is because it is very difficult to know whether a CME is bound and if it is, exactly when it is arrived. After all, there are no satellites near the sun to recognize the speed of a CME. This data can only be recorded if the effect of the CME on the sun wind – the current of charged particles from the sun that drives in all directions in the solar system – is measured by the DSCOVR satellite by NOAA that creeps up the earth. DSCOVR measures the speed and magnetic intensity of the sun wind, which is of crucial importance for calculating the change. Only then can an Aurora display from the NOAA world room weather -forecast -forecast, but there is not much warning -only 30 minutes. The northern lights are the result of the sun wind, which interacts with the magnetic field of the earth.
The return of solar maximum?
The sun has an approximately 11-year cycle in which its magnetic activity bends and subsides. How active it becomes is measured by counting solar spots on its surface, dark spots that indicate complexity – and often create solar torches and cmes. The Solar Cycle Cycle 25 NASA and NOAA forecast Memanel announced the arrival of Solarmaxumum in October 2024, although the exact date has not been visible for a few years. Some maximum solar times have a double peak that we could now approach.
Even if the number of sun spots decreases, large Aurora displays are possible. “This period of the sun drop is characterized by a decreasing number of sun spots, but not necessarily through less effects, even after the solar maximum,” said Lisa Upton, co-chair of NASA and NOAAS solar cycle 25 forecast. In fact, the falling phase of the solar maximum can see extreme sun events.
I wish you a clear heaven and wide eyes.
