Nobeyama Radioheliograph Event 19940116_2317


Note: 
  There are anomalous spikes in the flux plot
  that are probably due to the artifacts.
  Special care is necessary when using the given images in the archive.

Partial 17GHz images. Color map shows brightness temperature, contour shows 17GHz (r-l)/(r+l) levels, where 'r' and 'l' indicates right- and left-handed circularly-polarized components, respectively. Field of View is 314. x 314. arcsec
Contour levels of the thick lines are (r-l)/(r+l)=-0.1,-0.2,.. and those of the thin lines are (r-l)/(r+l)= +0.1,+0.2,...
Orange circle at top-left indicates the half-max. beam size
