Apod 4.2

This amazing Apod photo of the day may give some people the impression that the sun is going out of control. However, the photo was taken on March 30th by the Solar Dynamics Observatory. This photo of the sun is a depiction of the flase-colored sun is the composite view that covers the extreme ultraviolet wavelengths that traces the hot plasma at temperature that reach 1 million Kelvin. The SDO will send about 1.5 terabytes of data back to each each day. the recent data released includes a high-reslution movie of the large and eruptive provinces that are quite apparent along the solar limb at the upper left of the photo. This also photo shows the sun in a discolored version is an extremely interesting way to examine details of the sun that you may have missed once before.
