20080322 prominences

A collection of prominences visible late in the day on Easter Sat. I measured the largest of the prominences, - the arched one, as having a span of at least approx 240,000km or 2/3 of the Earth - moon distance. (this assumes that the arch is perpendicular to the Earth - Sun direction, in practice it is probably aligned at some other angle, and so would be greater than 240,000km)


other sizes: small medium large original auto
