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.Comment: Submitted to The Mining Geological Petroleum Engineering Bulletin
