Euclid Spots a Spiral Galaxy

The spiral galaxy IC 342, located about 11 million light-years from Earth, lies behind the crowded plane of the Milky Way: Dust, gas, and stars obscure it from our view. Euclid used its near-infrared instrument to peer through the dust and study it.

Solar Activity
Solar activity reached high levels this period with 7 M-class flares, all but two from Region 3932 (S18E06, Fkc/beta-gamma). The largest flare of the period was an M4.9/Sb at 25/0449 UTC which had an associated Type II sweep (1064 km/s). An associated CME was observed in LASCO starting near 25/0500 UTC. This event is being analyzed at the time of this summary. Newly numbered Region 3938 (N20E59, Dsi/beta-gamma) produced M-class activity, including an M2.8 flare at 25/0430 UTC.
Solar Wind
Solar wind parameters varied this period. Total field was at nominal background levels, with a peak of 6 nT, and Bz varying between +/- 5 nT. Solar wind speeds slowly decreased from ~550-500 km/s. The phi angle remained predominantly negative.
Energetic Particle
The greater than 10 MeV proton flux remained elevated above background but well below the S1 threshold, mostly due to activity that erupted on the far side of the Sun over 20 Dec. The greater than 2 MeV electron flux reached moderate levels.
