Re: Solar Talk - Monday 23rd November 19.30UT
Mark,
You did an outstanding presentation here! Wonderful! You should have been a teacher. I started out back in the late 1970's and early 80's drawing and notebook recording my white-light observations using 50mm and 60mm refractors and those little eyepiece solar filters and later projection. I would take an instamatic camera and photograph the images. I still have my old notebooks and the 60mm refractor! Living at 35 degrees north latitude I have seen an aurora only once in my life. Back around 1980-81. It was in the north and was not green but red!
If I understand radiation exposure right, cosmic rays are worse at minimum. Our atmosphere shrinks lowering protection against them and the sun is less active to " push them away " and it's heliosphere is smaller. Cosmic rays are LOWER during maximum but solar radiation is higher forcing planes to a lower altitude during CME events. Cosmic rays of course do not originate from the Sun but are from events far outside the solar system.
And I had no idea the sun had belts. That explains why we see the southern hemisphere coming alive now and it explains the double-peaks on the activity graphs.
I wish for more activity but certainly not a Carrington-Class event. I bet it would short out our computers, including the ones in our cars out too. And think, we would be hand driving our mounts, lol, I do that anyway, after the power went out. But that would be the least of our problems....
Thanks again Mark. Awesome presentation!!
