- Curator's comments
- In 1868, Janssen and Lockyer independently, in India and in England respectively, had papers presented at the French Academy of Sciences on the same day, concerning their dicoveries of a method of observation of solar prominences in the absence of an eclipse, and the Academy commissioned a struck medal in 1872 to commemorate their joint discovery.
See R. K. Kochhar, "French astronomers in India during the 17th - 19th centuries", 'Journal of the British Astronomical Association', 1991, vol.101, no.2, pp.95-100.
For another struck version of the medal, see 1906,1103.539; and for a restrike, slightly smaller (by 1 mm) version with a different edge and finish, and a slight variation in design (one star in a different position), see 1931,0507.83; for a large, cast, uniface, version of the obverse, see M.6960.
A ticket accompanying medal 1906,1103.539 is inscribed, possibly by Parkes Weber, with the following information:
