Three solar flares occurred over a 24-hour period this week. While we may not see them with a naked eye, they can affect Earth. Here's how.
The sun is entering a new phase and it's going to have serious repercussions for human life. Experts: Sun’s increasing solar flares could cause major problems Skip to main content
Our life-giving death star is experiencing its "solar maximum," which sounds like the name of a Christian rock band and is defined as the peak activity period within the sun's 11-year solar cycle.
Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
A solar flare from a sunspot region associated with this activity and preceding this period produced the then largest flare detected during the Space Age at about X20 (the first event to saturate spaceborne monitoring instruments, this was exceeded in 2003) but was directed away from Earth.
Solar flares strongly influence space weather near the Earth. They can produce streams of highly energetic particles in the solar wind, known as a solar proton event. These particles can impact the Earth's magnetosphere in the form of a geomagnetic storm and present radiation hazards to spacecraft and astronauts. A solar flare
Solar flares decrease as the sun nears solar minimum. So, throughout the 11-year solar cycle, flares may occur several times a day or only a few times per month, according to NASA.
A propagation effect is anything that impacts the path or state of an electromagnetic wave after it is produced. These effects therefore depend on whatever mediums the wave passed through before being observed. The most dramatic impacts to solar radio emission occur in the corona and in Earth's ionosphere. There are three primary effects ...
