Aloha!
The Suns surface has been very interesting to follow the past few days. A fascinating solar filament stretching across the surface is one of the longest recorded, over 700,000 km long. Solar filaments are made up of unstable plasma held above the solar surface by the Sun’s magnetic field.
I was able to observe it for 2 days in a row and marvelled over its sheer size, looking like a tear in the Suns surface. On this day there was also an interesting filament like region near the west limb that was wide and appeared dimensional in light and dark values. The “wishbone” prominence to the north appeared to be from beyond where the limb was visible, the top portion reaching toward the observer.
