Nobeyama Radioheliograph (17 GHz)
Movie
This GIF movie well demonstrates
the excellent imaging that is possible with large interferometer arrays
designed specifically for the Sun. Click on the animation or the

Very Large Array (VLA) Flare Movie
This GIF movie shows another
long-duration flare (contours) observed at the Very Large Array radiotelescope
and superimposed on Ha
images taken with a high-speed camera. This view from above allows
us to watch the development of magnetic loops filled with energetic electrons.

Nobeyama Radioheliograph Erupting
Prominence Movie
This GIF movie shows a very
large prominence protruding from the solar limb that erupts rather spectacularly.
Such eruptions and their associated coronal mass ejections, when directed
at the Earth, can cause magnetic storms and other problems. The radio
disk of the Sun has been subtracted away, so that we see only the arc of
the solar limb along the left edge of the frame, and the erupting prominence
heading toward the right. Click on the image at the left to start
the GIF movie (910 kb), or select the "caption" link for more information
about the animation.

Nobeyama Radioheliograph Flare
Ejecta Movie
This GIF movie looks similar
to the one above, but this is quite different from a prominence eruption.
Instead, this movie shows a flare-related plasmoid shooting up into an
existing loop, and shortly after the loop erupts. The solar disk
is seen along the right edge of the frame. Click on the image at the left
to start the GIF movie (474 kb), or select the "caption" link for more
