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.

Solar X-ray Imager (SXI) are full-disc X-ray instruments observing the Sun aboard GOES satellites. The SXI on GOES 12 was the first of its kind and allows the U.S. NOAA to better monitor and predict space weather .
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.
The SWPC and Nasa satellites have been monitoring recent activity of strong solar flares, which originate from sunspot regions. "A flurry of activity occurred the weekend of 28-29 December as ...
NASA’s Solar Dynamics Observatory captured this image of a solar flare on Oct. 1, 2024. NASA had a busy start to October, as the agency announced that the sun emitted several major solar flares ...
It's the biggest flare of this 11-year solar cycle, which is approaching its peak, according to NOAA. The sun produced its biggest flare in nearly a decade Tuesday, just days after severe solar ...
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.

A solar flare is an intense burst of radiation associated with sunspots that releases magnetic energy out into space, according to NASA. These giant explosions from the sun send energy, light, and ...
