VLA 20160218

Overview

(write a brief summary of the observation) 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 has coordination 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	Event	Location	RHESSI	Quicklook Image	Comments
19:43-19:44	C1.2@19:59		No		Few stripes at lower frequency, maybe in the pre-flare phase of the C-flare.
20:08-20:10	C1.2@19:59		No		Type III like features at lower frequency (which frequency range?) and broadband gyrosynchrotron emission across entire 1-2 GHz
21:09-21:12	C1.8@21:08	N03E23	Yes	File:2110.png	Quasi-periodic pulsations in impulsive phase. Highest RHESSI response @ 25keV. Radio source located near a footpoint.
