after a long period of clouds and rain, i could finally start with imaging of comet 46P/WIRTANEN and do some spectrosocopic observations of Castor and V442 And. The weather was not very good due the clouds that came over from time to time.
update observations comet 46P/WIRTANEN on 5 dec
I updated my website with the daily observations of comet 46P/WIRTANEN which where obtained from ROAD observatory, San Pedro, Chile in colaboration with F.-J. Hambsch. 46P on 30 nov., 46P on 1 dec., 46P on 2dec, 46P on 3 dec. , 46P on 4dec, 46P on 5 dec.
comet and spectroscopic observations on 30 nov.2018
a clear night after 2 weeks of clouds and rain. First is must rebuild a complete pointingmodel for my ASA mount, due a softwarecrash. After that i could obtain some comets: 29P/S-W1, 31P/S-W (dubious detection), 46P/WIRTANEN (now on about 16° above horizon in the severe lightpolution area, 64P and C/2017 T2. Then clouds where coming in and i must interupt the observations. With BRIXIIS-II observatory, several spectrocopic observations are made: VV Cep, 28 Cyg, V442 And, HD 26398 and Pleione. I made some changes on the setting of the grating, so i must take a ref.star again for the instrument response correction, but due the clouds i must interrupt the observations as well.
remote observations comet 46P/WIRTANEN 29 nov.

observations comet 46P/WIRTANEN last 4 days (25 nov.)
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.
spectroscopic observations on 18 nov.
spectroscopic observation on 17 nov.2018
spectroscopic observations on 15 nov.
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 .
