摘要

We observed X-ray bright points (XBPs) in a quiet region of the Sun with the X-Ray Telescope (XRT) aboard the Hinode satellite on 2006 December 19. XRT's high-resolution X-ray images revealed many XBPs with complicated structure and evolving dramatically with time. Almost all of the dynamic eruptions in the quiet region were composed of XBPs, and they had either loop or multiloop shapes, as is observed in larger flares. Brightening XBPs had strong magnetic fields with opposite polarities near their footpoints. While we have found a possible example of associated magnetic cancellation, other XBPs brighten and fade without any associated movement of the photospheric magnetic field.
