The Sun has unleashed a powerful solar flare, Nasa has said. The flare, designated X2.3, belongs to the most intense X class of flares. It was spotted by Nasa’s Solar Dynamics Observatory, which ...
A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.
It was observed and recorded independently by British astronomers Richard Carrington and Richard Hodgson—the first records of a solar flare. A geomagnetic storm of this magnitude occurring today has the potential to cause widespread electrical disruptions, blackouts and damage due to extended cuts of the electrical power grid. [3] [4] [5]
How can solar flares affect technology? Solar flares only affect Earth when they occur on the side of the sun facing Earth, NASA says. Past solar flares have caused issues with technology, but it ...
The flare was rated an R3-strength (flares are rated R1-R5, with R1 being the weakest) by NOAA, meaning that it may cause a "strong" radio blackout. "Today's X9 (R3) flare was prolific, but ...
Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare". It is caused by the reflection toward the Earth below of sunlight incident on satellite surfaces such as solar panels and antennas (e.g., synthetic aperture radar ).
Every 11 years, the sun's magnetic field reaches its solar maximum, in which the number of solar flares is at its highest, according to NOAA. PHOTO: Wisconsin's night sky is glowing with the ...
Caused by an X8-class solar flare aimed directly at Earth Apr 2001 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 ...
