14. TCV [Oulu]
spaceweb@oulu.fi - last update: 20 September 1998, 2020 UT (RR) . Traveling Convection Vortex (TCV) is a name given to a specific type of daytime magnetic impulsive events observed by high-latitude ground-based magnetometer arrays. Since the most likely source for TCVs is the solar wind , they are considered to be important processes in transfering energy from the solar wind into the magnetosphere . ... For example, one AMPTE Lithium release in the solar wind caused a TCV event . ...

... Several years ago, John Butler and myself derived the radiative energy output from the `quiet' corona of some twenty odd stars, similar in many ways to our own Sun, and found that there was a one-to-one correspondence with the total amount of energy radiated during flares on these stars over a period of say one day. ... The velocities derived increase from 0 km/s at 20,000K to a red-shift of 10 km/s at 190,000 K for the quiet Sun, and to 15 km/s 100,000 K for the active region. ...
