Dark grey/yellow observation of the Sun, 13 May 1882
Splodgy dark grey/yellow observation of sunspots made by John Willis on 13 May 1882 at 6pm. On the reverse Willis has noted "This view of the sun was very fine - The bright faculae on the eastern limb were very conspicuous - and scarcely any drawing could give an adequate idea of their appearance. - The large group of spots are evidently the same as three visible on the 16 April, though somewhat altered in appearance. 13.5.82 - J.W." Faculae are areas of greater brightness on the Sun that are hotter; sunspots are cooler. One of 275 pencil, ink and colour wash observations of the Sun and Jupiter made by Willis in Folkestone between 1879 and 1906.
