The Nobeyama Radioheliograph was completed in two years by 1992 March. It has been put into regular observations in late June 1992 for eight hours a day from 23h UT to 07h UT. It has caught some part of maximum activities of the Sun, but not so large as the flares in 1991 June. Observational results are described for faint structures on the Sun; an introduction to previous reviews is also given. Recent developments of image deconvolution software at Nobeyama are very promising to produce images of high‐dynamic range or of high quality. Examples of improved images with Steer algorithm are demonstrated. This image synthesis program will be released at Nobeyama for open use of the observed correlation data. The first light of the Dual‐frequency observations is also presented.
