Floating fragments of sea ice spun into intricate patterns as ocean currents carried them south along Greenland’s east coast in spring 2024. The MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Terra satellite captured a moment of this dizzying journey on June 4, 2024.

Solar Activity
Solar activity reached moderate levels with multiple C-class flares and three M-Class flares. There are currently seven regions on the visible disk with the two most complex areas near center disk. Active Region 3712 (S26W12, Ekc/beta-gamma-delta) produced an M1.5/Sn flare at 17/0804 UTC and an M1.5/1b flare at 17/1046 UTC which had an associated Type-II (411 km/s) radio sweep. Region 3712 remained relatively stable, with slight growth and penumbral consolidation observed across the intermediate spot area. Region 3716 (N10W05, Dkc/beta-gamma) continues to grow larger with an increasing spot count, but was quiet. The remaining regions were either stable or experienced slight decay.
Solar Wind
The solar wind has been slightly elevated due to the arrival of a high speed stream (HSS) associated with a positive polarity coronal hole (CH). Solar wind speeds ranged between 400-560 km/s since 00 UTC and have oscillated around 450 km/s through the day. The total interplanetary magnetic field strength reached a peak of 12 nT at 17/1659 UTC and the Bz component has been predominantly negative reaching a minimum of -10 nT at 17/2321 UTC. The phi angle was moslty positive.
Energetic Particle
The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was at background levels.
