This movie shows the magnetic field in the corona of the sun derived
from GONG data. Magnetic field lines that are closed on the Sun are
shown in blue, those that are open to interplanetary space are shown in
red (negative inward pointing field polarity) and green (positive
polarity). The fields are plotted over the magnetic field image, whose
flux density is indicated by a grey scale from white
(maximum-strength positive flux) to black (maximum-strength negative
flux). GONG continually obtains a full-disk magnetic field image every
minute, and creates several products that are placed on the Web in
near-real time for the research community. These products include
10-minute-average images, hourly updated synoptic maps, and seven
projections of the extrapolated magnetic field (also updated on an
hourly basis).
The movie covers Carrington Rotations 2054-2056 (March-April 2007). |

This MPEG movie contains 863 frames of high-resolution image-merged GONG network magnetograms from 031203:01:01 to 040107:23:01; averaged over 11 minutes in each hour; gap-filled by synthetically rotating the Sun and interpolating between frames before and after each gap. Gap-filled frames are indicated by a * after the date stamp. A simple zero-point correction has been applied.
