Saharan Dust in the Wind

Thursday, 29 August 2024

Dense bands of dust streamed offshore from southern Morocco in summer 2024. The VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite acquired this image of a plume of Saharan dust as winds lofted it over the Atlantic Ocean on Aug. 24, 2024.

Solar Activity
Solar activity reached moderate levels. Region 3932 (S17E54, Ekc/beta) produced an impulsive M1.9 flare at 21/0038 UTC; the largest event of the period. Region 3927 (S08E25, Hsx/alpha) was split this period, with the lead spot maintaining the 3927 designation, and following intermediate and trailer spots being named new Region 3933 (S08E34, Dao/beta). Minor to moderate growth was observed in Regions 3928 (S14E34, Dai/beta), 3930 (S22W49, Cai/beta), 3932, and 3933.
Solar Wind
Solar wind parameters were mildly enhanced this period. Total field strength reached 9 nT and the Bz component varied between +/-8 nT. Solar wind speeds ranged between 450-560 km/s. Phi angle was predominantly oriented in the negative sector.
Energetic Particle
The greater than 10 MeV proton flux was elevated around 4 pfu, but remained below S1 (Minor) levels. The greater than 2 MeV electron flux was at normal to moderate levels. .Forecast... The greater than 10 MeV proton flux is expected to remain below S1 (Minor) levels over 22-24 Dec. The greater than 2 MeV electron flux is expected to continue at normal to moderate levels through 24 Dec.
