October 17, 2010 #088 - Spokes on Saturn's Rings in 1888

NASA

As I was reading a Google scan of the February, 1888 - "The Journal of the Liverpool Astronomical Society", I was surprised when I looked at Plate XII (Figure 14 & 19). It is a drawing by a Society member, Thomas Gwyn Elger, of Saturn's Rings. What was striking about his drawings was an apparent record of "spokes" on the Rings. If memory serves me, I have read that these ghost like markings were discovered during the Voyager Mission as it scanned Saturn at the end of the 20th. century and more recently by the Cassini Mission. It appears to me that Mr. Elger may have got a jump on us by about a hundred years!

With a little Wiki research I found that Mr. Elger was a lunar mapper who had an observatory with an 8.5 inch refractor in Bedford, England. He was the first director of the Lunar Section of the British Astronomical Association and was a member of several other Astronomical Societies. His 1895 book - "The Moon: A Full description and Map of its Principal Physical Features" is highly regarded due to it's maps. (Available on Google Books) His sketches from 1884 to 1896 are now in the possession of the BAA. He even has a crater on the moon named in his honor.



These drawings and his notes are included for you to take a look at.
