Large sunspots have been rare in early April. Nevertheless, when cloudless skies and mild temperatures beckoned I set up my solar telescope and camera for some Sun watching. On April 7th only a single sunspot, numbered 1450, had nearly finished rotating across the Sun's disk. But this lonely sunspot was accompanied by an enormous, sinuous filament shown in the panoramic image below.
