Event overview of the 19 day corotating type IV continuum. (a) Solar Orbiter/RPW dynamic spectrum (Window 1). (b) Wind/WAVES and (c) Parker Solar Probe/FIELDS flux (Window 2; Wind-Parker Solar Probe overlap). (d) Parker Solar Probe circular polarization V/I (negative values correspond to left-hand circular polarization). (e) STEREO-A/WAVES flux (Window 3). (f) STEREO-A circular polarization V/I. (g)–(i) STEREO-A wavevector azimuth, colatitude, and apparent source size. The apparent cutoff at 2 MHz reflects the direction-finding data product limitation.
