BRIXIIS Observatory activities

during this clear evening and later, after midnight, moon disturbance, i took also images of comets as follow-up with the 0.4-m f/3.8 telescope: comets which are observed are: 29P,  C/2016 R2, C/2017 K2, C/2018 W2, C/2019 J2 (not detected), C/2019 K4, C/2019 L3 and C/2019 N1. stars where a spectrum is taken are: HD 175863, nu Cyg, cx Dra and 10 Cas.

spectroscopic observations are obtained with the C11 and LHiResIII septrograph with 2400 l/mm grating. Stars which are observed are:  HD169033, HD 207232, omi Her.

comet observations with the 0.4-m f/3.8 newton telescoop: C/2016 R2, C/2017 K2, C/2018 U1, C/2019 N1

during this evening several Be-stars are observed with spectrograph LHiResIII and 2400 l/mm grating: 28 Cyg, V2120 Cyg, V442 And, 60 Oph. Also with the 0.4-m f/3.8 telescope, some comets are observed (sky SQM in zenit 19.25) : 68P, C/2016 R2, C/2017 K2, C/2018 U1, C/2019 D1 (not detected), C/2019 K8, C/2019 L3, C/2019 M3, C/2019 N1

during this clear night (SQM – zenit here about 19.25) i observed comets with the 0.4-m f/3.8 corrected newton: 29P, 68P, 260P, 114P (not detected), A/2019 K6 (not detected), C/2016 R2, C/2017 E3 (not detected), C/2017 K2, C/2018 N2,  C/2018 U1, C/2018 W2, C/2019 D1, C/2019 J3 (not detected), C/2019 K4, C/2019 K8, C/2019 L3, C/2019 M3, C/2019 N1.  With the C11 and LHiResIII spectrograph (with grating 2400 l/mm) several be-stars are observed: 31 Aqr, pi Aqr, Alfirk, 1730 Vul, 58 nu-Cyg, 31 Peg

During this hot evening, i started with comet observations and spectroscopic observations of some Be-stars. Be-stars which are observed are: 28 Cyg, omi And, omi Cas,  lam Cyg, gam Cas .   Unfortunately later on this night, cirrus clouds where coming in and i loos a lot of contrast, so i interrupt the observations. Comets which are observed are: 68P/KLEMOLA, C/2019 J2 (PALOMAR) (not detected), C/2019 L3 (ATLAS) and C/2019 M3 (ATLAS).
