Gas flows in the transition region above sunspots
- 1. Oslo Universitetet (Norway)
Description
Strong downflows and moderate upflows in the transition region over a sunspot have been observed with the Spacelab 2 HRTS in 1985. The flows are found to be persistent, and it is suggested that they are common. Data show that the downflows are supersonic and that there is more than one characteristic flow speed in the downflows. Evidence is provided for constant downflows in the 30,000-230,000-K temperature range. 31 references
