The Sun can produce large-scale energetic events such as solar flares and coronal mass ejections (CMEs), which are often associated with accelerated particles and emission at radio wavelengths. To date, the site of and mechanisms responsible for particle acceleration are not well known. Here, we investigate these phenomena using radio observations of the September 10, 2017 X8.2 solar flare at 10-240 MHz from the recently constructed Irish Low Frequency Array (I-LOFAR; www.lofar.ie<http://www.lofar.ie>). The flare was located on the western limb and was on of the largest of a series of flares produced from NOAA Active Region 12673. The CME reached speeds of ~3000 km/s and the produced a shock that arrived at Earth 51 hours later. In this poster, we present I-LOFAR observations of Type III radio bursts associated with the expanding flank of a CME and a Type II radio burst associated with the shock driven by the CME. These observations allow us to better understand the nature and origin of accelerated particles associated with solar flares.
