Tell us how complex sunspots are and contribute to protecting human beings in and near outer space.

What is Sunspotter?

Although the Sun is 150 million km away, its activity affects us. Eruptions from sunspot groups can coat the Earth with X-rays and high-energy particles, endangering astronauts and the ISS, interrupting GPS signals, damaging our satellite infrastructure, exposing high-altitude and high-latitude aircrafts to radiation, and even disrupting the electrical grid. The Sunspotter project aims to expand human knowledge about the Sun and more effectively protect human beings in and near outer space.

What do you do?

Sunspotter aims to construct a reliable measure of sunspot group complexity.  For this, you have to take pictures of a sunspot group, and tell how complex the group is on a scale from 1 to 10. This will help answer the following questions: are sunspots born complex or do they evolve to become complex? Do complex sunspot groups produce more eruptions?
