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

List of Events/Features
| Time | Feature | Event | AIA Movie | RHESSI | Quicklook Images | Comments |
| 19:43-19:44 | small stripes | Maybe A6.4Microflare@19:43 | Near solar disk center | No | File:1943.png | Few stripes at lower frequency below 1.5GHz, maybe a microflare. Radio flux increase corresponding the west source. |
| 20:08-20:10 | Type III | C1.2@19:59 | Near Ar2501 | No | File:2008ty3.png | Type III like features at lower frequency around 1~1.3 GHz, Radio source locate on the limb |
| 20:08-20:10 | Broadband GS | C1.2@19:59 | Near Ar2501 | No | File:2008GS.png | Broadband gyrosynchrotron emission across entire 1-2 GHz band, Radio source locate on the limb |
| 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. |
