AR 2738 – April 15 and 16, 2019

Scroll down to content

A lovely large sunspot is evolving on the Sun these days, with currently B-class flares and a possible breakup. The views below show the spot in white light and H-alpha. Note the chromosphere in the animation as it stands above the photosphere.

Bresser 150mm achromat refractor, Quark Chromosphere for H-alpha, Lacerta Herschel prism for white light. ASI 174MM. Poor seeing as the Sun was about 35-40 degrees above horizon.
