# ALMA Solar Ephemeris Generator

## TL;DR

The paper introduces an online tool that simplifies the calculation of solar surface feature positions, aiding in ALMA solar observations and adaptable for other observatories.

## Contribution

It presents a user-friendly online ephemeris generator specifically designed for solar features, enhancing observation planning for ALMA and other facilities.

## Key findings

- Successfully used for ALMA solar observation planning
- Provides accurate predicted positions of solar features
- Easy integration with ALMA Observing Tool

## Abstract

An online software tool for the easy preparation of ephemerides of the solar surface features is presented. It was developed as a helper tool for the preparation of observations of the Sun with the Atacama Large Millimeter/submillimeter Array (ALMA), but it can be used at other observatories as well. The tool features an easy to use point-and-click graphical user interface with the possibility to enter or adjust input parameters, while the result is a table of predicted positions in the celestial equatorial coordinate system, suitable for import into the ALMA Observing Tool software. The tool has been successfully used for the preparation and execution of solar observations with ALMA.
