comet and spectroscopic observations on 3 jan.

I decided to open my observatory to observe some comets as follow-up, especially 64P. I have only 1 … 1.5 hour because clouds where coming.. observed comets are 46P and 64P. Spectroscopic observation of the binary HD20120 was obtained with the C11 telescope and LHiResIII spectrograph as a first test ot participate with my French friends for a project.
