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.
