Correlation between increases of magnetic fluxes
and brightenings of coronal structures around
emerging flux regions
Keiji Yoshimura
One of the main topics about Solar-B sciences should be, of course,
relationships between various magnetic features on the photosphere
and coronal diverse structures.
I found examples of some correlation between total magnetic fluxes
in emerging flux regions (EFRs) and brightness of coronal structures
around the EFRs. The bright coronal structures appeared at the side
of the EFRs in TRACE EUV images along with the increases of magnetic
fluxes in the EFRs. The structures were visible in 171 angstrom images,
but not in 195 images. They persisted on a time scale of hours and
spread laterally to the widths of the EFRs. They were likely bunches
of loops which were partially visible.
