CMEchaser, detecting line-of-sight occultations due to Coronal Mass Ejections

TL;DR

CMEchaser is a Python tool designed to detect when background sources are occulted by solar coronal mass ejections, facilitating analysis of archival data with a user-friendly interface.

Contribution

The paper introduces CMEchaser, a novel Python-based tool that automates the detection of line-of-sight occultations caused by CMEs using standard celestial coordinates.

Findings

Effective detection of CME occultations in archival data

Utilizes Astropy and Sunpy for accurate coordinate transformations

Enables large-scale searches for CME events

Abstract

We present a python-based tool to detect the occultation of background sources by foreground Solar coronal mass ejections. The tool takes as input standard celestial coordinates of the source and translates those to the Helioprojective plane, and is thus well suited for use with a wide variety of background astronomical sources. This tool provides an easy means to search through a large archival dataset for such crossings and relies on the well-tested Astropy and Sunpy modules.
