Title	Parkes observations for project P885 semester 2019APRS_01

Creator	Fernando Camilo

Subject	Astronomical and Space Sciences not elsewhere classified

Description	We propose to observe the magnetars 1E 1547.0-5408 and PSR J1622-4950 approximately weekly, to track their rotation, flux density, and polarisation, as we have been doing through this project. As of this week (8 Dec 2018), XTE J1810-197 is again a radio magnetar, after 10 years dormant! (We have been observing it sporadically during its low state waiting for such an event.) Its likely chaotic rotation will be better tracked in detail elsewhere, but weekly observations with the UWL receiver will provide unique measurements of its radio spectrum and broad-band behaviour. Our observations provide an important window into remarkably dynamic magnetar magnetospheres, and characterise the conditions under which radio emission takes place therein, placing constraints on the emission mechanisms, which in at least some significant respects differ from those of ordinary pulsars.
