I did not see last Monday's eclipse, except on television. Here in
the Pacific Northwest, we only got a 20% exposure, and skies were
overcast.

As they moved across the country displaying successive totality, I

between one and three little red spots at the edge.

Solar activity over the past reporting week, April 4-10, remains
weak.

With the big increase in sunspot numbers and solar flux reported in
