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.
