The Solar X-ray Imager obtains images at multiple wavelengths on the electromagnetic spectrum from 6 to 60 angstrom units (Å). [3] The imagery obtained by the XSI and XRS on GOES 12 allowed forecasters to see space phenomena such as coronal holes , whose geomagnetic and proton storms impact electrical grid systems on Earth as well as radio ...
In solar physics and observation, an active region is a temporary feature in the Sun's atmosphere characterized by a strong and complex magnetic field.They are often associated with sunspots and are commonly the source of violent eruptions such as coronal mass ejections and solar flares. [1]
The ionospheric disturbance enhances VLF radio propagation. Scientists on the ground can use this enhancement to detect solar flares; by monitoring the signal strength of a distant VLF transmitter, sudden ionospheric disturbances (SIDs) are recorded and indicate when solar flares have taken place.

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.
When that magnetic activity is released, it creates intense bursts of radiation resulting in solar flares – considered by NASA to be our solar system's largest explosive events. Solar flares ...
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 ...
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.
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.
