Query: Microflaring of a solar Bright point   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 10^4 - 6 10^5 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.
