Maps of Solar Eclipses from 1835 to 1839
During the annular solar eclipse of May 15, 1836, astronomy Francis Baily observed and recorded a curious phenomenon which we now call Baily’s Beads. The lunar surface is irregular with craters and mountains and during an eclipse, the gaps between these features on the limb of the Moon in silhouette will create brilliant bits of sunshine. Baily observed this effect and understood its cause.
You can read about Baily’s observations in a paper titled On a Remarkable Phenomenon that occurs in Total and Annular Eclipses of the Sun at https://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?bibcode=1838MmRAS..10....1B
Baily’s Beads is a striking effect seen when an annular or total solar eclipse is about to reach its fullness and was seen and described in earlier eclipses. Baily’s account was the first to describe this phenomenon in detail and today bears his name.
