SDO: The Sun Magnetogram (Field Lines)
The magnetogram image shows the magnetic field in the solar photosphere, with black and white indicating opposite polarities. This feed also shows any named active regions.
Note: This feed is updated at unpredictable intervals. It may be slightly delayed from other Sun feeds. This is also why it appears jerky in video form.
