On 31st March 2019, a new simplebipolar active region emerged in the NE of the Sun. This region formed from asmall bright point, and developed through expansion. For the first time, weobserve the development and expansion of the loops with time, and with magneticmodelling see how the region at the edge of the active region form anincreasing number of open magnetic field lines. We see the development of theregion where blue-shifts form. These blue-shifted regions are always seen atthe edges of active regions as observed by the Hinode EUV Imagining Spectrometer (EIS), and wediscuss how they are formed. Alongside these observations, Parker Solar Probeobserved a radio noise storm. We track how the blue-shifted and the radio dataincrease as the active region develops in its first few days of life. Theblue-shifted regions on the active region seems to be the source of the radionoise storm, confirming their importance as a contributor to the solar wind.
