The VLA can image the Sun with unprecedented high cadence (50 ms), spectral resolution (up to 1 MHz, or ~0.1% of the total bandwidth), and spatial resolution (~10?). Its unique capability of imaging coherent radio bursts at decimetric radio wavelengths allows tracing flare-accelerated electrons to their origin: the flare energy release site. Meanwhile, X-ray and EUV observations provide important complementary information of the flare geometry, dynamics, and plasma heating. The recent discovery of a solar flare termination shock (Chen et al. 2015, Science, 350, 1238) has clearly demonstrated the power of using such multi-wavelength observations to study flares. We have been awarded 30 hours of VLA time to observe solar flares from 2016 Feb 5 to Apr 25. The VLA observations will be supported by the NuSTAR.We will also propose for IRIS coordination.
