Imaging riometer of two-dimensional multi-narrow beams is a powerful radio instrument to investigate the structure of cosmic noise absorption (CNA) in the auroral ionosphere caused by the precipitation of energetic electrons. However, the instrument has a demerit of delay-look for imaging because of the use of a large capacity computer for data processing. Quick-look (QL) system of the imaging riometer was developed by using a personal computer. This system has a function to view the CNA images in real time. Quiet day curves (QDC's) which indicate the condition of quiet ionosphere are determined from daily variations of cosmic noise intensity obtained during the initial ten days. Thereafter the QDC's are set into real-time data processing as a reference. The QL system has an advantage for real-time comparison with auroral images by the all-sky TV camera.
