This tool allows you to calculate the oriented figure of the solar disk which you can copy and paste on your images in order to inform of the position of the north-south axis of the Sun.

SpotLight

Use the position ruler to locate solar prominences relative to the Sun's north-south axis

This information is important in order to develop statistical models based on the position of areas of remarkable solar activity.

SolarRule

Place the template on the photo of the Sun. Adjust the size of the inner circle on the solar limb and rotate the template until it coincides with the object to be measured.

This tool also makes it possible to measure the height of prominences and solar flares from the limb.

Sol'Ex
