Hey ASOD!

Why did the GRS get lighter and smaller after 1975?
As you see under my sketch, the GRS was brickred before a white spot became in
and passed the GRS on 9. nov. -75.
The GRS had allways a brick-red color before this happened, and since then, it
has been light red, orange or yellow!
The GRS was very easy to see on the disc of the planet before that!
Can anyone tell what happened?

I used color – pencils on black paper.
Loc.: Trondheim, Norway.

Best wishes Per-Jonny Bremseth.

    I can remember well those doys of the big, oval red spot.
    Nice sketch from the old days.
