Microflaring of a solar Bright point
Abstract
A solar X-ray Bright point (BP) was observed with the SUMER-spectrograph of the SOHO-observatory. The data consist of four far-UV spectral lines formed between 2 104 - 6 105 K, with 2 arcsec spatial, 2.8 min temporal and 4 km/s spectral resolution. A striking feature is the strong microflaring and appearance of several short lived transients. Using simultaneous magnetic field measurements the region observed seemed to lie above a cancelling flux region. With respect to the filling factor and emission measure this particular BP was similar to the average surface of a moderately active solar type star.
