Images from GONG

	This image 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 colorized 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). TIFF format image. This and other products based on the near-real-time GONG synoptic magnetograms are available on the GONG synoptic magnetogram page.
