The story

Plate I of The Trouvelot Astronomical Drawings, Charles Scribner's Sons, New York, 1881: a group of sun spots and veiled spots, observed on June 17, 1875, at half past seven in the morning. The Sun was Étienne Léopold Trouvelot's particular interest, and the veiled spots were his own find, made that same year. Sunspots are cooler regions where knots of magnetic flux hold back the Sun's churning surface; they come in pairs, grow and shrink, and rise and fall on a cycle of about eleven years. Trouvelot made about 7,000 astronomical drawings in his life. Fifteen were published as chromolithographs, and this one opens the set.
