White light network in the solar photosphere

Time-averaging technique is performed on a set of white light pictures obtained at μ=0.87. After eliminating short-lived granulations, the time-averaged pictures show some large scale but longlived brightness patterns which are not recognizable in any of the single frame snapshots. The patterns are brighter than the background and are co-spatial with the upper photospheric emissions and magnetic fields. We define these patterns as the white light network.
