Session: INS4: LOFAR, the LOw Frequency ARray: Ongoing Developments and Early Results

Presentation type: Poster      Poster Session B   

Summary:

Interplanetary scintillation (IPS) is a powerful means of observing the Sun’s extended atmosphere – the solar wind – through remote sensing. IPS – the twinkling of radio waves from a distant, compact, astronomical natural radio source – results from density inhomogeneities traversing the interplanetary medium moving outward from the Sun. Using the newly-developed IPS experiment on the novel European-based radio telescope, the LOw Frequency ARray (LOFAR), we have our first detection of a coronal mass ejection (CME) passing through one of our preliminary observations of IPS during the ongoing commissioning phase of the LOFAR system. Here, we identify the CME in white-light imagery, and briefly discuss and compare its characteristics/properties with other sources of data where available. We also note how such work will be taken forward with on-going test observations of IPS using LOFAR, and look to the future to fully combine LOFAR observations of IPS with those taken using other systems worldwide, including the European Incoherent SCATter (EISCAT) radar and the Multi-Element Radio-Linked Interferometer Network (MERLIN) which are also located within Europe along with LOFAR.
