The Space Weather Prediction Center is one of the nine National Centers for Environmental Prediction (NCEP) and provides real-time monitoring and forecasting of solar and geophysical events, conducts research in solar-terrestrial physics (i.e. heliophysics), and develops techniques for forecasting solar and geophysical disturbances.
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.

The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.
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]
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 ...
A solar flare is an intense burst of radiation near a sunspot that releases magnetic energy out into space, according to NASA. These giant explosions from the sun send energy, light, and particles ...
On 8 May 2024, a solar active region which had been assigned the NOAA region number 13664 (AR3664) produced an X1.0-class and multiple M-class solar flares and launched several coronal mass ejections (CMEs) toward Earth. [6] On 9 May, the active region produced an X2.25- and X1.12-class flare each associated with a full-halo CME.
The sun spit out the huge flare on Thursday, resulting in two hours of radio interference in parts of the U.S. and other sunlit parts of the world. Scientists said it was the biggest flare since 2017.
