# Photometric observations of the asteroid 3200 Phaethon using small and middle telescopes

## TL;DR

This study used small to medium telescopes to observe asteroid 3200 Phaethon, aiming to detect possible cometary activity and model its 3D shape, while also estimating its color indices and size.

## Contribution

It provides new photometric data and shape modeling of Phaethon using a range of telescopes, focusing on detecting low-level cometary activity.

## Key findings

- No significant cometary activity detected.
- Estimated color indices and size of Phaethon.
- Modeled 3D shape based on photometric series.

## Abstract

The main aim of photometrical observations of the asteroid 3200 Phaethon was searching for its low-level cometary activity (possible coma and/or dust tail) in the pre-perihelion passage. We performed observational runs with telescopes ranging from 0.61-m to 2-m and BVR color imaging. Three longer photometric series were used for modeling of the 3D shape of Phaethon. The color indices and size of the asteroid were estimated.
