Description
I will give an update on our Interplanetary Scintillation (IPS) project, in particular the finalised IPS catalogue consisting of over 5000 sources. I will describe the latest comparison with International Lofar, and our efforts to use these more conventional interferometric measurements to calibrate our IPS measurements, and how we might also attempt more detailed mapping of sub-arcsecond source structure.
More broadly we have been applying our IPS technique to EoR observations in order to understand ionospheric scintillation; both as an interesting phenomenon in its own right, and as a potential contaminant in other radio measurements, especially IPS. Early indications are that IPS is significant, and that ionospheric scintillation has a magnitude in line with predictions ($\sim$1% - $\sim$10% scintillation indices). However it is only weakly correlated with other indicators of ionospheric activity.
