![]() ![]() The HSO is comprised of several heliospheric, geospace and planetary spacecraft that watch the sun and measure its activity. NASA also has a fleet of spacecraft - known collectively as the Heliophysics Systems Observatory (HSO) - designed to study the sun and its influence on the solar system, including the effects of space weather. They monitor and record changes in sunspot size, number and position to evaluate the likelihood of an Earth-directed solar flare and/or CME from an active region. Scientists at the National Oceanic and Atmospheric Administration (NOAA)'s Space Weather Prediction Center analyze sunspot regions daily to assess the threats. However, we cannot be certain when the next Carrington-level event will occur as space weather is notoriously difficult to predict. Though solar storms with half the intensity of the Carrington Event are more frequent, occurring about every 50 years. Luckily for us, solar storms like the Carrington Event happen once every 500 years or so, according to NOAA SciJunks. When is the next Carrington Event?Ī composite image of the sun produced by the Solar Orbiter spacecraft in March 2022. have estimated that a Carrington-class event today would result in between $0.6 and $2.6 trillion in damages to the U.S. ![]() Researchers from Lloyd's of London and the Atmospheric and Environmental Research agency in the U.S. government lists adverse space weather as one of the most serious natural hazards in its National Risk Register, and companies have contingency plans to deal with severe events - as long as they have sufficient warning of them. It’s been conjectured that a storm on the scale of the Carrington event, if it happened today, could cause an internet apocalypse, sending large numbers of people and businesses offline. While solar storms rarely pose a direct threat to human life, there’s a risk they can impact safety-critical systems via electromagnetic effects - from space-based communications, navigation and weather forecasting services to electrical power distribution at ground level, according to ESA's Space Weather Service Network So now is a good time to look at the worst solar storms.ĭuring the Carrington Event, northern lights (aurora borealis) were witnessed as far south as Cuba! (Image credit: Noppawat Tom Charoensinphon via Getty Images) What would happen if a storm like the Carrington Event happened today? Sunspot activity rises and falls on an 11-year cycle, and we're currently approaching the next solar maximum in 2025. ![]() It's from these spots that solar flares, coronal mass ejections and other electromagnetic phenomena can emerge - with potentially hazardous consequences for our technological way of life. The origins of space weather can be traced to contortions in the sun's magnetic field, leading to dark blotches or sunspots on its surface, according to NASA Earth Observatory. The solar storm of 1859 is now known as the Carrington Event in his honor. This was a connection that had never previously been made, according to NASA Spaceflight. The program overlays NASA and USGS satellite imagery, aerial photography, topographic maps, Keyhole Markup Language (KML) and Collada files.The day after Carrington observed the impressive flare, Earth experienced an unprecedented geomagnetic storm, with telegraph systems going haywire and auroral displays - normally confined to polar latitudes - visible in the tropics, according to NASA Science.Ĭarrington put two and two together and realized that the solar flare he'd seen was almost certainly the cause of this massive geomagnetic disturbance.
