Description:
We request Hinode and IRIS coordination to support flare observations by the Jansky Very Large Array (VLA) at radio wavelengths. 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.
