... April 13, 1998 . The Sun Changes . ... Explanation: Our Sun changes every day. This recent picture was taken in a very specific red color called Hydrogen-Alpha . Dark spots that might appear on the image are usually sunspots , dark magnetic depressions that are slightly cooler than the rest of the Sun's surface. Bright spots that might appear are usually plages , active regions that are slightly hotter than the rest of the Sun's surface. ... About APOD > . ...

... The active time at each angular bin is the sum over frames of the active time contributions from all CCD pixels, within the node-specific telemetry window, which overlap the surface of the bin. ... The active time, per frame, of a normal pixel is the full frame integration time multiplied by the node-specific fractional exposure; bad pixels contribute no active time. ... If an event is rejected for this reason only, then its pixels remain normal in the exposure map. ...
