Around solar minimum, solar flares might occur less than once per week. The amount of energy released is equivalent to millions of nuclear bombs exploding all at the same time! Solar flares are an often occurrence when the Sun is active in the years around solar maximum. Material is heated to many millions of degrees in just minutes and radiation is emitted across virtually the entire electromagnetic spectrum, from radio waves at the long wavelength end, through optical emission to X-rays and gamma rays at the short wavelength end. ![]() A solar flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released. A solar flare is defined as a sudden, rapid, and intense variation in brightness. That’s good news for Northern Lights fans, but there could be some serious connectivity and power problems for civilization, especially considering it comes at a time when we’re more dependent on satellite communications than ever before.A solar flare is basically a giant explosion on the surface of our Sun which occurs when magnetic field lines from sunspots tangle and erupt. Many space watchers forecast an increasing number of sunspots and solar flares between now and sometime in the next few years before activity resumes.īy some accounts, this current solar cycle phase called solar maximum has already been more active than expected and may be one for the record books. The Sun is moving toward the peak of activity in its 11-year cycle of sunspot activity. It also enlarges the aurora borealis and aurora australis, making them potentially more active and visible at lower latitudes.Īll this could be just the beginning. Such space weather could be harmful to spacecraft in orbit and could deliver small doses of radiation to astronauts on the International Space Station.

The sun gave off several CMEs as well as two strong M flares over the weekend, which move much slower than the particles in the flares. In the most extreme cases, bursts and bursts of charged plasma called coronal mass ejections (CMEs) can often affect electrical equipment and grids on the ground. However, flares can also briefly disrupt radio and satellite communications in the part of the world that is in line of fire, including navigation systems such as GPS. These bursts of radiation travel at the speed of light, reaching Earth in less than ten minutes, but our planet’s magnetosphere prevents most energetic explosions from reaching the surface. ![]() Solar flares are bursts of energetic particles that usually erupt from sunspots on the Sun’s surface. While an X1 is a significant flare, flares up to X28 have been recorded which, according to NASA, overloaded the sensor during the most powerful flare in 2003. Each letter is ten times more powerful than the previous, so an X-flare is ten times more powerful than an M flare and 100 times more intense than a C flare. Flares are grouped by intensity into C, M and X class flares with X flares being the most powerful. The eruption was classified as an X1 class flare, peaking at 4:25 p.m. ![]() NASA’s Solar Dynamics Observatory and other Sun watchers picked up an intense X-class flare from our local star on Sunday afternoon, the most powerful burst of energy seen from the Sun since May 10. A powerful X-flare from the Sun as recorded in 2003. ![]()
