AR4419 produces M1-class solar flare in the northwest of the Sun; plasma filament eruption recorded in the southwest

• The active region AR4419, located in the northwest quadrant of the Sun, produced an M1 class solar flare on Tuesday, March 24, 2026. At the same time, on the southwest side of the solar disk, a plasma filament flare was recorded, a phenomenon that is often associated with mass ejection.

• A coronal mass eruption (CME) of M1 class, while moderate, is significant enough to potentially cause disruptions in high-frequency radio communications and could generate a CME directed toward Earth in the coming hours or days. The filament eruption in the southwest could also contribute to geomagnetic activity should the plasma ejection head in our direction.

• Observatories such as NASA's Solar Dynamics Observatory (SDO) and NOAA's GOES have clearly recorded both events. Images show the intense brightness characteristic of the M1 eruption and the plasma material being expelled from the filament in the southwest. To date, NOAA's Space Weather Prediction Center (SWPC) maintains heightened vigilance. If the ejections are confirmed and directed towards Earth, it is possible that auroras will be visible at lower latitudes and that there may be impacts on satellites and power grids in the coming days.

• This is the second notable eruption of AR4419 in just a few days, indicating that the region remains active and could produce stronger events (class M or even X) in the next 48-72 hours.
