Space Weather dot com report reveals a quiet Sun, with huge streaks of magnetic filament streaking across it.
From the report:
The sunspot number may be low, but the sun is far from blank. Amateur astronomers monitoring the sun report a large number of magnetic filaments snaking across the solar disk. Sergio Castillo captured more than half a dozen in this picture he sends from his backyard observatory in Inglewood, California.”
The report continues:
“Filaments are popping up all over the solar surface,” says Castillo. “Each one has a unique shape and length.”
The longest one, in the sun’s southern hemisphere stretches, more than 400,000 km from end to end. “It’s one of the longest filamentary structures I have ever seen,” says veteran observer Bob Runyan of Shelton, Nebraska.
If any of the filaments collapses, it could hit the stellar surface and explode, producing a Hyder flare. Filaments can also become unstable and erupt outward, hurling pieces of themselves into space. Either way, astronomers with solar telescopes are encouraged to monitor developments.
