The solar storms of May 2024 are an ongoing powerful series of solar storms with intense to extreme solar flare and geomagnetic storm components ongoing since 10 May 2024. These storms were seen as far south as Florida, during solar cycle 25.[1][2] The storm produced aurorae at far lower latitudes than usual in both northern and southern hemispheres.[3]
Solar flares and coronal mass ejections
On 8 May 2024, a solar active region, which had been assigned the NOAA region number 3664, produced multiple near X-class and X-class solar flares and launched several coronal mass ejections (CME) in Earth's direction. The following day, the active region produced two additional X-class flares (X2.25 and X1.12) associated with two full-halo CMEs. The region produced X3.98 flare the next day and on 11 May it produced X5.89 flare with another asymmetrical full-halo CME.[4][5][6][7][8] The region also caused a S1 solar radiation storm with spikes to S2.[citation needed]
The eruption of an additional X5.4-class solar flare was reported 11 May 2024 at 01:23 UTC.[9]
Geomagnetic storm
Three CMEs from 8 May reached Earth on 10 May 2024, causing severe to extreme geomagnetic storm with bright and very long-lasting aurorae. Aurorae could be seen from Europe immediately after sunset even in Croatia.[10] In North America aurorae were seen as far south as Florida[11] and Zacatecas.[12] In the southern hemisphere the aurora was seen in New Zealand,[13] Australia,[14] Chile and Argentina.[15] Due to the interplanetary magnetic field reaching a magnitude of 73 nT with the component along Earth's magnetic axis oriented strongly south, reaching −50 nT, as well as due to moderately high solar wind density and speed reaching 750–800 km/s,[when?] the event was classified as G5-class geomagnetic storm, making it the most intense storm since the 2003 Halloween solar storms.[8] Several other CMEs are expected to reach on 11 and 12 May.[16]
Comparison to other solar storms
The disturbance storm time index is a measure in the context of space weather. A negative Dst value means that Earth's magnetic field is weakened. This is particularly the case during solar storms. The May 1921 geomagnetic storm had estimates of intensity of Dst = −907±132 nT, whilst estimates for the Carrington Event superstorm of 1859 are between −800 nT and −1750 nT.[17]
Currently, the highest negative measurement for the May 2024 solar storms is −412 nT.[18]
