Today I got a newsletter from NASA & it talks about the "Blue Moon" events.
Have a look here:
Blue Moon
It confirms my memories: The time was 1883, the year an Indonesian volcano named Krakatoa exploded. This explosion caused great clouds of dust to rise up into the high atmosphere & circle the world which produced a blue moon to be seen in all the world.
Apparently ash from forest fires can produce the same effects - something I didnīt know about.
