Update of the website with the observations of comet 46P/WIRTANEN + update Af(rho) graph. 46P on 21 nov, 46P on 22 nov, 46P on 23 nov. 46P on 25 nov – Af(rho) parameter graph update.
it is a clear night with some high clouds. i decided to observe some Be-stars which are more faint and where i didn’t have any spectrum: HD 199218, HD 193182, HD 192445.
a clear (cold) night and very low humidity in the air, excellent conditions for observing. spectroscopic observations are obtained from the C11 with LHiResIII spectrograph: RR Lyr, V764 Cas, HD 206773, VV Cep.
during this evening i did some spectroscopic observations with the LHiResIII spectrograph: HD 203699, pi Aqr and HD 206773 which i must interrupt due clouds which are coming in .
between cloudy period i could do some spectroscopic observations during a clear period in the evening: HD 224544, HD 23552, 18 And.
some spectroscopic observations are obtained with the LHiResII spectrograph during this evening: VV Cep, RR Lyr and gam Cas.
We can start now, after some test imaging runs of comet 46P/WIRTANEN, with daily follow-up. In collaboration with Franz-Josef Hambsch and his remote observatory (ROAD) in Chile (IAU G39). check-out the overview of 46P/WIRTANEN Observations … Read more
during e short period of clear wky, i could obtain some spectra of Be-stars with the LHiResIII, unfortunate, clouds were coming in , so i couldn’t start with the RR Lyr observation: stars that could … Read more
