A large solar filament is currently stretching across the southeast quadrant. It is so long that is measures over 350,000 km in length and is transitioning into a prominence off the southeast limb. Every now and then these plasma rich features can become magnetically unstable and collapse leading to odd shaped coronal mass ejections. For now it remains anchored in place. A full description of what a prominence / filament is can be found below. A prominence is a large, bright plasma feature extending outward from the Sun's surface when viewed against the darkness of space around the edges (limbs) of the Sun. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's hot outer atmosphere, called the corona. This same feature is called a filament when viewed above the solar surface and appear as dark, dense lines. They are one of the most common solar features, especially towards solar maximum. Most times they remain magnetically anchored in place or fall back toward the Sun, although every now and then they can erupt and lead to coronal mass ejections. SolarHam.com |

Two Events At Once May 23, 2024 @ 02:35 UTC Quite a busy past hour on the Sun. In addition to the prominence eruption in progress off the southeast limb, an M4.2 solar flare was just observed around AR 3679 nearing the west limb at 02:16 UTC (May 23). So far it does not appear that an Earth directed CME will be associated with either event, but additional imagery will be required to make a final determination. Stay tuned for more updates. |
