Multiband Color Monitoring of 3I/ATLAS through Ground-Based Relay Observations
Ariel Graykowski, Bryce Bolin, Laura-May Abron +140
We present multiband, long-baseline photometric observations of interstellar comet 3I throughout its 2025--2026 apparition using coordinated ground-based global relay observations.…
Photometry of comet 29P/Schwassmann-Wachmann 1 in 2012-2019
Olena Shubina, Valery Kleshchonok, Oleksandra Ivanova +2
The analysis of photometrical observations of comet 29P/Schwassmann-Wachmann 1 is presented. The broadband observations were carried out for 15 nights from 2012 to 2019 at the Lisn…
Long-lasting activity of asteroid (248370) 2005 QN 173
Oleksandra Ivanova, Javier Licandro, Fernando Moreno +8
We present the results of observations of asteroid (248370) QN obtained during July 2021 - January 2022 with three telescopes. Our analysis revealed the presence of the dus…

Oleksandra Ivanova, Igor Luk'yanyk, Dušan Tomko +1
We present an analysis of the photometric and spectroscopic observations of the split comet C/2019 Y4 (ATLAS). Observations were carried out on the 14th and 16th of April 2020 when…
Imaging polarimetry and photometry of comet 21P/Giacobini-Zinner
E. Chornaya E. Zubko, I. Luk'yanyk, A. Kochergin +8
We report results of polarimetric observations of comet 21P/Giacobini-Zinner made at phase angles, α=76-78 deg, between 10 and 17 of September 2018, and compare them with previous…
Monitoring polarization in comet 46P/Wirtanen
M. Zheltobryukhov, E. Zubko, E. Chornaya +9
We measure the degree of linear polarization of comet 46P/Wirtanen during two months, embracing the perihelion passage in 2018 December with phase angles ranging from α=18.1 to 46.…
Extremely low linear polarization of comet C/2018 V1 (Machholz-Fujikawa-Iwamoto)
E. Zubko, E. Chornaya, M. Zheltobryukhov +8
We measured the degree of linear polarization P of comet C/2018 V1 (Machholz-Fujikawa-Iwamoto) with the broadband Johnson V filter in mid-November of 2018. Within a radius of \r{ho…
