abstract = "We present a study of decimetric radio activity, associated with
two (GOES C1.4 and M1.0 class) flares and a coronal mass ejection
(CME) of 20 June 2015, using the first high time cadence (0.5s)
610 MHz observations of the Giant Meterwave Radio Telescope
(GMRT). The GMRT images show strong radio sources during the M1.0
flare and CME, which are located near the flaring site, while, in
contrary, a strong spike radio source during the C1.4 flare, with
no corresponding coronal or magnetic features, are rather located
about 500 arcsec away from the flare site in soft X-rays. Although
weak radio burst sources are located near the flaring site, during
the C1.4 flare maximum, associated with the spike radio source,
which show a good temporal correspondence with a metric typeIII
burst identified by the Solar Broadband Radio Spectrometer at
Yunnan Astronomical Observatory. A multi-wavelength analysis, in
combination with potential field source surface extrapolation, has
been carried out to investigate the genesis of non-thermal radio
emitting electrons, which revealed that the distant spike radio
source, noticed during the C1.4 flare, is actually connected to
the main electron acceleration sites and is generated by a plasma
emission instead of a loss cone maser instability.",
