Looks like a M6III - M7III spectrum.

Hen 4-129 from last night. I don't have expertise to make classification of it but have submitted the fits file to Francois and Jaroslav.

Hi all,

IRAS 18120+4530 and KIC 4918300.
IRAS 18120+430 seems to be a symbiotic system.

Very faint stars for my setup but a really nice challenge

Two others candidates taken in automatic mode from Chile last night :

- AL 4 (Mag. V=14,80) nothing to see, only a continuum

Image


- AS 241 (Mag. V=15,80) Balmer's lines in emission

Hello all,

Here is my new contribution to this classification program with DV Aur which is identified as a long period variable in the Simbad database.
I obtained the following spectrum of DV Aur the 18th of September at 1 h 52 TU with my Alpy 600 (resolution of 509, JJ = 2459840.5781) and an acquisition time of 60 min (6 x 600s) :
