                         high time cadence (0.5 s) images from the Giant Meterwave Radio 
                         Telescope (GMRT) at 610 MHz associated with GOES C1.4- and 
                         M1.0-class solar flares and a coronal mass ejection (CME) onset 
                         that occurred on 2015 June 20. The high spatial resolution images 
                         from GMRT show a strong radio source during the C1.4 flare located 
                         \∼500\″ away from the flaring site with no 
                         corresponding bright footpoints or coronal features nearby. In 
                         contrast, however, strong radio sources are found near the flaring 
                         site during the M1.0 flare and around the CME onset time. Weak 
                         radio sources located near the flaring site are also found during 
                         the maximum of the C1.4 flare activity that show a temporal 
                         association with metric Type III bursts identified by the Solar 
                         Broadband Radio Spectrometer at Yunnan Astronomical Observatory. 
                         Based on a multiwavelength analysis and magnetic potential field 
                         source surface extrapolations, we suggest that the source 
                         electrons of GMRT radio sources and metric Type III bursts 
                         originated from a common electron acceleration site. We also show 
                         that the strong GMRT radio source is generated by a coherent 
                         emission process, and its apparent location far from the flaring 
                         site is possibly due to the wave-ducting effect.",
