Collection consists of white-light (unfiltered), full-disk images of the sun provided
by various solar observatories and institutions. White light pictures show how the
Sun appears to the naked eye, when all the colors of the rainbow are collected by
the camera. In a white light photo, the part of the Sun that we see is called the
"photosphere". It has a temperature of about 6000 degrees Celsius, much cooler than
the corona. |
