Scientists recorded a giant "king prominence" measuring the size of 80 Earths.
On the night of November 20 a huge solar prominence formed and detached at the Sun’s north pole, its size at the moment of detachment exceeding 1 million kilometers. For comparison — that is roughly 80 times the diameter of the Earth.
As scientists note, the source of the process is located on the far side of the Sun and is not yet accessible to observations. However, there are grounds to suspect a connection between this event and another large plasma ejection that occurred three days earlier in the same region. At that time the cloud most likely headed toward the interstellar object 3I/ATLAS, which is about 230 million km from the Sun.
Experts believe both events may be related to active solar region 4274, which last week, while it was still on the Earth-facing side, produced the two largest flares of the year — X5.1 and X4.0. That region has now moved onto the far side of the Sun.
Laboratory researchers note that in scale the current ejection is not much inferior to the legendary 1946 “Grand Daddy” prominence.
