Sunspot AR1785 evolution over 2 days
Sunspot AR1785 is evolving and changing shape rapidly as it crosses the sun. The top part of this image was taken late evening two days ago and the bottom is today’s image from this morning. In that time it has stretched and lengthened by more than 40,000 km, 11 times as wide as the Earth (source – spaceweather.com). The images are taken using white light Baader solar film at full aperture on a Skywatcher 200p telescope.
