Helioseismic and Magnetic Imager First Light Briefing

About

NASA Caption: The Helioseismic and Magnetic Imager

The HMI will measure the waves rippling across the surface of the Sun and the strength and direction of the surface magnetic field. Wave data is used to create ultrasounds of the Sun, looking under the surface of the Sun to measure the winds that create the magnetic field. The magnetic field data is used to understand how the field erupts through the surface and becomes solar flares and coronal mass ejections, the storms of space weather.

This video is converted from the original video's frame rate of 60 to a slower frame rate of 15 which in turn allows a lower bitrate so that more computer users can replay it without pauses. Some artifacts are unavoidable during this conversion.
