Parkes observations for project P878 semester 2015APRS

Measuring the magnetic field and electron density of the solar wind is essential in order to understand the properties of solar corona. Detection of dispersion measure (DM) and Faraday rotation measure (RM) of linearly polarized radio sources caused by the solar wind provides a unique opportunity to measure these properties. Pulsars are therefore ideal sources for such study, especially for millisecond pulsars which can be used to obtain high timing precision to measure the DM variations caused by the solar wind. The millisecond pulsars, PSR J1022+1001 and others in the globular cluster M28 and Terzan 5 with ecliptic latitude of only -0.06, -1.55 and -1.37 degree are ideal for this work as the line-of-sight to these pulsars goes very close to the Sun. We can use these pulsars detect the different regions of the solar coronal, such as solar equator and south pole region. We also propose a unique study of the solar corona on small physical scales using the lines-of-sight to multiple pulsars in the M28 and Terzan 5 globular cluster.
