| Abstract: |
A soft X-ray (SXR) coronal loop sometimes appears to connect
between opposite photospheric magnetic polarity elements
in a newly emerging magnetic bipole.
We looked into the photospheric magnetic field data
of high spatial resolution
around this kind of SXR loop brightenings.
While around most of them
we found many magnetic cancellation events, which can release enough
energies to make the coronal loops brighten in SXR through magnetic
reconnection,
we did not find any corresponding cancellation around some of the brightenings.
And we did not clearly find any SXR enhancements above the magnetic
cancellation site.
These observational facts suggest that there must be some
other mechanisms to heat up the coronal loops. |
