NSO / AURA / NSF Something New Under the Sun " My opinion, " Campbell says, " is that you have to start with the building blocks of the solar atmosphere - what's happening with the magnetic field on the smallest scales in the photosphere. And you have to build the picture up from that point, if you want to try and solve the problem. " Building the picture also requires multiple perspectives. Rimmele has used his director's discretionary time to organize coordinated observations of the corona with Parker Solar Probe and Solar Orbiter. Parker flies through the outer corona, while Solar Orbiter measures particles from the Sun (particularly the poles) blowing through the solar system. The goal is to build a 3D understanding of coronal magnetic 20 NOVEMBER 2023 * SKY & TELESCOPE THE FIRST SUNSPOT This color-adjusted image is the first taken by DKIST of a sunspot, at a wavelength of 530 nm. The heart-shaped umbra is the size of the contiguous United States. structure by combining the view from Earth with those from spacecraft on different orbits. Gone with the Wind The ubiquitous effects of the Sun go beyond temperature alone. In 1959 the Soviet spacecraft Luna 1 detected a strange flow of charged particles while en route to the Moon. This was the first direct observation of what we now call the solar
