Technical Summary: We propose to use MDI magnetograms and Dopplergrams for a correlative study of the emergence of NOAA 7978 on 1996 July 6 from 14:00 UT to 24:00 UT. We will compare the change of the magnetogram images with that of radio images which we have obtained using the VLA. We have already processed the VLA data to determine the change of radio flux, area, and intensity associated with the EFR event. MDI magnetograms of this region will be used to identify locations of foot-points of the coronal magnetic fields where the radio emission comes from. We will examine the positional and temporal correlation of the radio images with the magnetogram images to investigate which physical parameter is the most responsible for the increase of radio emission associated with the EFR. We also hope to learn how the magnetic fields expands and forms an arch filament as they rise above the coronal base by matching the locations of polarized radio sources with those of the photospheric magnetic fields seen on the magnetograms.
