I am 99% certain that I won't be driving 12 hours to Texas to join millions of my closest friends to view the eclipse on 8 April. Instead I will make do with the 73% coverage that will be visible here in Santa Fe. Yesterday and today I did some test images to get my camera settings dialed in. The telescope was an Orion 80mmED with a Lunt solar wedge and a ND-0.6 filter.

There is a large and active sunspot group that is about to rotate out of view around the western limb. Counterintuitively, this is a dangerous position for solar flares. A phenomenon known as the "Parker Spiral" causes charged particles to follow a magnetic flux spiral backward toward Earth. There was a radio blackout over the Pacific Ocean yesterday caused by a solar storm from this sunspot.
