The project Sun4All aims to promote science in general and astronomy in particular. The project is based on an asset of over 30000 images of the Sun (spectroheliograms) that are kept at the Astronomical Observatory of the University of Coimbra, as result of a work of over 80 years of daily solar observations, started in 1926. This is a Sun observation collection of great scientific value.

The project aims at involving all citizens in the analysis and counting of the sunspots is a very important aspect of the study of the phenomena occurring on the surface of Sun and to understand the solar activity and solar cycle. On the other hand studying the sunspots, besides being interesting itself, presents an important tool to understand much of what happens on the Earth climate.
