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]
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.
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 ...

Solar radio bursts are brief periods during which the Sun's radio emission is elevated above the background level. [16] They are signatures of the same processes that lead to the more widely-known forms of solar activity such as sunspots, solar flares, and coronal mass ejections. [17]
The communications blackouts that affect spacecraft re-entering the Earth's atmosphere, which are also known as radio blackouts, ionization blackouts, or reentry blackouts, are caused by an envelope of ionized air around the craft, created by the heat from the compression of the atmosphere by the craft. The ionized air interferes with radio ...
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.
