• Sunspot Light-Bridges • A Bridge from the Photosphere to the Corona? Light-bridges are lanes of bright material that divide the umbra in a sunspot. They are often observed during the break-up of sunspots and therefore can represent the re-establishment of convection which is normally inhibited by the sunspot's strong magnetic field. Their increased brightness suggests a higher plasma temperature than in the surrounding umbra, and they have been shown to display significantly enhanced chromosph
