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 ...

Since 1996, geomagnetic storms and solar flares have been monitored from the Solar and Heliospheric Observatory (SOHO) satellite, a joint project of NASA and the European Space Agency (ESA). Extreme geomagnetic storms were registered in 2003 and 2024, both sparking northern lights as far south as Florida.
May 2024 solar storms: X1.2(X1.3)-class flares [93] and X4.5-class flare. [94] The flares with a magnitude of 6–7 occurred between 30 April and 4 May 2024. On 5 May the strength of the solar storm reached 5 points, which is considered strong according to the K-index. The rapidly growing sunspot AR3663 became the most active spot of the 25th ...
A NASA telescope has captured the biggest solar flare in years, which temporarily knocked out radio communication on Earth. Multiple pilots reported communication disruptions, with the impact felt ...
The 4 August flare was among the largest since records began. [10] It saturated the Solrad 9 X-ray sensor at approximately X5.3 but was estimated to be in the vicinity of X20, [11] the threshold of the very rarely reached R5 on the NOAA radio blackout space weather scale. [12] A radio burst of 76,000 sfu was measured at 1 GHz. [8]
