A large collection of spectra has been gathered by Robin Leadbeater here http://www.threehillsobservatory.co.uk/epsaur_spectra.htm

By the way my spectra are present in both analysis as many other amateurs. Nothing can be done alone, this campaign was an example of what a pro am spectroscopic campaign should be.

An extended long term monitoring along the 27 years of the orbit is encouraged. Send any spectra to Robin Leadbeater as long as an on-line database will be available. Do it for the next generations.
