Limbdarkening during Partial Solar Eclipse

 


Plotting limbdarkening of the Sun.
  • black arrow is a crosssection of the limb including the two sunspots; both give a nice drop in the graph
  • red line is a crossection into the segment of the eclipse. 
The black line in the graph shows how the intensity is changed from limb to limb. The red line in the graph  has only one "drop" near the limb. The other "dark side" caused by the moon shows a sudden drop which is clearly different then the drop near the limb. 

Images of the Partial Solar Eclipse October 25

 


Picture of the partial Solar Eclipse of October 25, 2022, taken a couple of minutes before the end of the eclipse. The green color is because I'm using an OIII filter on top of a ND3.8 filter.
