# A confidence index for forecasting of meteor showers

## TL;DR

This paper introduces a confidence index for meteor shower forecasts, helping users assess the reliability of predictions by considering factors like parent body knowledge and planetary encounters.

## Contribution

It presents a novel confidence index that quantifies the trustworthiness of meteor shower forecasts based on current orbital and activity data.

## Key findings

- The index highlights the importance of parent body data.
- Close planetary encounters significantly affect forecast confidence.
- The approach improves understanding of forecast uncertainties.

## Abstract

The forecasting of meteor showers is currently very good at predicting the timing of meteor outbursts, but still needs further work regarding the level of a given shower. Moreover, uncertainties are rarely provided, leaving the end user (scientist, space agency or the public) with no way to evaluate how much the prediction is trustworthy. A confidence index for the forecasting of meteor showers is presented. It allows one to better understand how a specific forecasting has been performed. In particular, it underlines the role of our current knowledge of the parent body, its past orbit and past activity. The role of close encounters with planets for the time period considered is quantified as well. This confidence index is a first step towards better constrained forecasting of future meteor showers.
