Description

To study the ionosphere using LOFAR, strong radio sources such as Cassiopeia A (Cas A) or Cygnus A (Cyg A) are typically observed. However, few studies have explored the use of other sources, such as those from the 3C catalogue, for detecting ionospheric fluctuations. In my work with the LOFAR station LV614, I have conducted approximately 100 observations targeting 3C147 and 3C295, including both daytime and nighttime sessions.

I have successfully detected ionospheric activity using both sources. These observations were carried out in parallel with simulated observations of Cas A, enabling direct comparison with traditional ionospheric studies. In addition to data collected with station LV614, I have also performed observations using other international LOFAR stations. In all cases, ionospheric scintillations were detected.

In my poster, I will present the first results from these studies, demonstrating the potential of 3C sources for ionospheric research.
