Un eshel, un Alpy600 et une Sardine au foyer d'un superbe télescope récemment mis en service sur le plateau de Calern. Nôtre première nuit a été gachée par des pluies diluviennes. Mais le ciel clair est ensuite vite revenu, nous observons des étoiles variables mal connues et des astéroides. A nous les découvertes grâce au télescope de 1m du C2PU !

First spectra of a supernova  in the galaxy PGC 006399 (ATel 6714) taken at C2PU with an Alpy600 low resolution spectroscope

Somes others results:

First specta ever of Dauban V250

A large h beta line for this unknown type variable. A relative featureless spectra for a probable fast rotator object.

Spectra of HR326, A Be candidate

H alpha and H beta lines are fill in by a slight emission. No emission in HeI lines. Seems to be a good candidate.

New phase of matter ejection of IU Aur, last seen was in December, 2013

V/R variations of HD39478, may indicate a multiple system

End of P cyg profile phase in h alpha of HD36112, a Herbig Be star with stron stellar wind

First spectra of JCT3, a recently visual double star discover at Observatoire de la côte d'azur with the Nice great 76cm refractor by Jean Claude Thorel with an angular separation of 0.3 arcsecond. A K type star.

Profile variation of HD38191, double peak in H alpha and H beta lines

Screeshot of mag 8.2 star acquisition

Mission team at C2PU is composed by Pierre Dubreuil, Alain Lopez, Stephane Ubaud, Thibault De France and Thierry Garrel

More to come with Sardine, a new echelle spectroscope, Alpy 600 and even star analyzer on asteroids.
