As soon as the Solar disk is covered by the Moon, the Solar corona appears. The shape and size of the corona varies with time and Solar activity. The corona is visible throughout totality which can vary in length from just seconds up to a maximum of just over 7 minutes. This eclipse was viewed from LaPaz, Baja, Mexico. Totality lasted about 6 minutes, 52 seconds, the longest total solar eclipse for several hundred years in the future. Film: Kodachrome 64. Lens: 700mm f/11. Image scanned from slide.
