After the clouds were gone, i could start with observing. Colmets that could be observed are 12P, 103P, 237P, C/2023 E1 with my comet-setup of Newton telescope 0.4-m f/3.8. With the C11-telescope and LHiReSS III spectrograph, i could obtain 2 spectra of V442 And + 14 Lac in high resolution of the H-alpha region.
comet and spectroscipic observations on aug. 3
After an very long period of bad weather, this evening, this evening had a brief period of clear skies. I could obtain 2 spectra and 2 comets, after 2 hours clouds where coming in and i must close the 2 observatories. comets that are observed are: 12P and 103P. the spectra i could obtain are: V442 And and 10 Cas.
spectroscopic observations on 15 june
After a warm day and after the clouds cleared, I was able to start around 23h local time to record spectra of alpha Draconis for the STAROS project.
spectroscopic observations on 14 june
again a clear night. i could start around 23h local time in evening twilight with capturing a spectrum of alpha Draconis (spectroscopic double starsystem) in h-alpha region in high resolution (R~15000) with LHiRess and C11 setup, exposuretime was 6 x 600 sec (STAROS-project – This database concerns the star alpha Draconis (Thuban, HD123299), a relatively bright spectroscopic binary of type A0III (V=3.68), with an orbital period of 51 days.). After this star, i observed Be-star 10 Cas and exposuretime was 2 x 1200 sec. data for the BeSS database.
spectroscopi observation on 13 june
still very clear night with good transparancy. I took a spectrum in high resolution of H-alpha region of alpha Draconis in participating of the STAROS project.
spectroscopic observation on 10 june
a clear grey night (sun hole not lower than 18° below the horizon) again a high-resolution spectrum in H-alpha region of Alpha Draconis for STAROS project
spectroscopic observation on june 8.
It gets dark later and later each time and last night started high resolution spectrum of Alpha Dra for HR spectrum in H-lapha region. data can be found in the STAROS database .
spectroscopic and comet observations on 4 june
a clear night but cocktail of low transparancy, wind gusts and almost full monn (99%) disturbing ths observations/ comet that where observed are: 12P, 80P (not found), 103P (not found), C/2019 T4, C/2020 R7, C/2020 S4, C/2022 L2, C/2022 Q2 (uncertain), C/2022 V2, C/2022 U4, C/2023 E1. Spectroscopic observation for H-alpha region in high resolution (R > 15.000) of Alpha Draconis for STAROS project.
comet observations on 17 may
spectroscopic and comet observations on 25 april
a clear night as start was perfect to start with some observations. Comets that could be observed are: 65P, 118P, 119P, 180P, C/2019 U5. after the last comet, i must close the observatory due incoming clouds. With the C11 + LHiRess spectrograph i could obtaihne 2 spectra of the H-alpha region in high resolution of Be-stars: HD 175863, teta CRB.
