Solar protons are showering Earth’s upper atmosphere after an explosion from sunspot AR3599 on March 14th. This is causing a polar cap absorption event, absorbing shortwave radio transmissions within the Arctic Circle.

With the Solar Peak approaching, we can expect a surge in solar activity, bringing along powerful solar storms, flares, and coronal mass ejections (CMEs). These events can put Earth‘s satellites, telecommunications, and power grids at risk, possibly causing radio blackouts, electrical system disruptions, and significant blackouts.
Recently, on March 14th, Sunspot AR3599, a departing active region on the Sun’s surface, burst in a stunning explosion. This event unleashed a torrent of solar protons, which are now raining down on Earth’s upper atmosphere. The impact of these highly energetic particles is disrupting shortwave radio transmissions within the Arctic Circle.
According to SpaceWeather.com, the ionizing effect of the protons is absorbing radio signals, leading to communication disruptions in the region. This event is expected to persist for at least another 24 hours, affecting various activities that rely on shortwave radio transmissions in the Arctic.
Auroras During Equinox
As the vernal equinox approaches on March 20th, skywatchers and aurora enthusiasts must be excited. Equinoxes are the times of the year when day and night are almost equal in length. There are two equinoxes: one in spring and one in autumn. In spring, the equinox happens around March 20th or 21st, and it marks the start of spring in the northern hemisphere and autumn in the southern hemisphere. During an equinox, the Sun crosses the sky’s celestial equator, making day and night almost the same length everywhere on Earth. That’s why we call it an “equinox,” which means “equal night” in Latin.
During the equinoxes, a phenomenon known as the “Russell-McPherron effect” occurs. This allows even weak blows of solar wind to trigger auroral displays.
Researchers have observed that cracks form in Earth’s magnetic field at this time of year providing an open pathway for charged particles from the solar wind to interact with our planet’s upper atmosphere. As these particles collide with atmospheric gases, they produce auroral lights.
For those living in high-latitude regions, the upcoming equinox presents an excellent opportunity to witness the auroras, the report added.
