Solar Triangle!
On 09/05/2025 01:35 pm by David Hawkes | South Yorkshire, UK
Today we have a nice solar sunspot triangle bounded by region AR4207 at the northern apex, followed by AR4210 and AR4206 forming the remaining sides. Newcomer AR4211 in the southeast completes an additional diagonal line of spots.
Skywatcher 200P 8” Newtonian, 9.5” Seymour Solar glass white light solar filter, Antares 1.5x Barlow lens, Baader UV/IR cut filter, Nikon Z7 II.
