摘要: We use G-band and Call H image sequences from the Dutch Open Telescope (DOT) to study magnetic elements that appear as bright points in internetwork parts of quiet solar photosphere chromosphere. find many these recurrently with varying intensity horizontal motion within longer-lived patches. develop an algorithm for detection patches all identified last much longer than granulation. The outline cell patterns on mesogranular scales, indicating flux tubes are advected by granular flows boundaries. Statistical analysis emergence disappearance average patch lifetime long 530 ± 50 min (about nine hours), which suggests constituting strong fields not generated a local turbulent dynamo.
