[36.05] Observations of X-Ray Bright Points

K. L. Harvey (SPRC)

Since the launch of Yohkoh in 1991, a number of collaborative observing campaigns have been conducted to determine the association of X-Ray Bright Points (XBPs) with the underlying photospheric magnetic fields and chromospheric structures. Simultaneous, high-time and spatial observations were obtained by the Yohkoh Soft X-Ray Telescope and several ground-based observatories (NSO/KP, BBSO, MSO, NSO/SP, HAO, SOONSPOT).

In this paper, the results of the analysis of these data will be presented, focusing on and quantifying the XBP time and spatial variability, the association of XBPs with the evolution of the photospheric magnetic fields and of chromospheric structures observed in HeI 1083 nm and H\alpha. The interpretation of the XBP phenomena in terms of magnetic field reconnection will be considered.
