Part of Solar cycle 25 |
The solar storms of May 2024 are a series of powerful solar storms with intense to extreme solar flare and geomagnetic storm components that have been ongoing since 10 May 2024 during solar cycle 25. The geomagnetic storm produced aurorae at far lower latitudes than usual in both northern and southern hemispheres[1] with observations reported as far south as Florida.[2][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 an X1.0-class and multiple M-class solar flares and launched several coronal mass ejections (CMEs) toward Earth.[4] On 9 May, the active region produced an X2.25- and X1.12-class flare each associated with a full-halo CME. On 10 May, the region produced an X3.98-class flare, and on 11 May at 01:23 UTC it produced an X5.89-class flare with another asymmetrical full-halo CME.[5][6][7] The region also caused a S1 solar radiation storm with spikes reaching S2.[8]
Geomagnetic storm
Three CMEs from 8 May reached Earth on 10 May 2024, causing severe to extreme geomagnetic storms with bright and very long-lasting aurorae. Aurorae could be seen in Europe immediately after sunset from as far south as Croatia.[9] In North America, aurorae were seen as far south as Florida[10] and Zacatecas.[11] In the southern hemisphere, the aurora was seen in New Zealand,[12] Australia,[13] Chile and Argentina.[14] 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 (470–500 mi/s),[when?] the event was classified as a G5-class geomagnetic storm, making it the most intense storm since the 2003 Halloween solar storms.[15] Several other CMEs were expected to reach Earth on 11 and 12 May.[16]
Comparison to other solar storms
The disturbance storm time index (Dst index) is a measure in the context of space weather. A negative Dst index means that Earth's magnetic field is weakened. This is particularly the case during solar storms. The May 1921 geomagnetic storm has been estimated to have had a Dst index of −907±132 nT, whilst estimates for the Carrington Event superstorm of 1859 are between −800 nT and −1750 nT.[17]
As of 11 May 2024, the highest negative measurement for the May 2024 solar storms is −412 nT.[18]
