Large volcanic event on Io detected by sodium using C14 on AP 1100 mount

An article published at phys.org (https://phys.org/news/2019-01-sodium-reveals-volcanic-jupiter-moon.html) today reports on the detection of a large
volcanic eruption on Jupiter's moon Io that occurred sometime between
mid-December 2017 and early January 2018.

The discovery has been reported in a letter to the Astrophysical Journal.

Impressively, the equipment used was very modest, being of the type used by many amateur enthusiasts.

Very good report!
It’s sometimes amazing what can be done with amateur sized scopes.
Spectroscopy has been a very popular “tool” for the amateur and many observations have been made of IO’s sodium cloud etc.
Science observations does have to be difficult.

This would have to be on the playlist at night in any observatory in Benson, Arizona. :)
