Overview

This observation was made in C configuration (max baseline length 3 km) with the full array (27 antennas) in L band (1-2 GHz), with 2 MHz frequency resolution and 50 ms time resolution. The observation was coordinated with Hinode and IRIS (HOP 297). Two C-class flares were covered: A C1.2 eruptive flare at the limb N11W88 starting at 19:59 and a C1.4 flare from AR 2501 near the disk center N03E23. RHESSI data is available for the impulsive phase of the C1.4 flare. File:20160218 sum.png

  • link to VLA overview movie: this should have ~10 s cadence at several frequencies (perhaps one for each spw, so 8), zoomed in to the flare site.

List of Events/Features

Time Feature Event Location RHESSI Quicklook Images Comments
19:43-19:44 small stripes Maybe A6.4Microflare@19:43 Near solar disk center No Few stripes at lower frequency below 1.5GHz, maybe a microflare.
20:08-20:10 Type III, Broadband GS C1.2@19:59 ? No Type III like features at lower frequency (which frequency range?) and broadband gyrosynchrotron emission across entire 1-2 GHz band
21:09-21:12 Pulsations C1.8@21:08 Ar2501 near solar disk center Yes File:2110.png Quasi-periodic pulsations in impulsive phase. Highest RHESSI response @ 25keV. Radio source located near a footpoint.
