104 Spotless Days & Limb Darkening




The picture of the Sun today shows again a Sun without any sunspots. So far this year, 104 spotless days are registrated; in 2017, it took a full year for those 104 spotless days. This means we are heading towards a solar minimum.

The picture also shows the Sun is more bright at the center and darker towards the edges. This phenomena is called Limb Darkening - which I will explain later (when I have time :)


Sun with SolarMax III and ASI224MC


The Sun today around UT08h45 observed with SolarMax III (f/5.7 70/400 DS BF15) and ASI224MC for 60s. This time true color stacking providing a red color instead of BGGR blue color (see my blog here). 





The Sun with SolarMax3 and ASI224MC


The Sun this morning; observation with SolarMax 3 (f/5.7 70/400; BS en BF15) and ASI224MC. Capturesoftware SharpCap for 60s and stacking using AutoStakkert in BGGR. This results in a (false) blue color, but the provides a nive and higher contrast. Located centrally on the Sun's disk you can see a white bright active region, but without sunspots. Also different prominences can be see at the limb of the Sun.
