  First-of-its-kind radio imaging of decameter solar stationary type IV radio
burst has been presented in this paper. On 6 September 2014 the observations of
type IV burst radio emission have been carried out with the two-dimensional
heliograph based on the Ukrainian T-shaped radio telescope (UTR-2) together
with other telescope arrays. Starting at 09:55 UT and throughout 3 hours, the
radio emission was kept within the observational session of UTR-2. The
interesting observation covered the full evolution of this burst, "from birth
to death". During the event lifetime, two C-class solar X-ray flares with peak
times 11:29 UT and 12:24 UT took place. The time profile of this burst in radio
has a double-humped shape that can be explained by injection of energetic
electrons, accelerated by the two flares, into the burst source. According to
the heliographic observations we suggest the burst source was confined within a
high coronal loop, which was a part of a relatively slow coronal mass ejection.
The latter has been developed for several hours before the onset of the event.
Through analyzing about 1.5 million of heliograms (3700 temporal frames with
4096 images in each frame that correspond to the number of frequency channels)
the radio burst source imaging shows a fascinating dynamical evolution. Both
space-based (GOES, SDO, SOHO, STEREO) data and various ground-based
instrumentation (ORFEES, NDA, RSTO, NRH) records have been used for this study.
