Parker Solar Probe: what it is and why it really matters
Parker Solar Probe flies through the corona and measures plasma, fields and particles much closer to the Sun than previous missions. Its data sample solar wind before it is heavily processed during its outward journey.
What it really means
For Aurora Hunter, separating observation from modelling is essential. A sensor can describe what is happening now; a model combines measurements and assumptions to estimate what may happen next. Confusing the two creates false certainty. A very precise-looking number should not hide uncertainty. Resolution, filtering, algorithms and delays can make two valid products differ without either being wrong.
Why it matters
Even the best data have limits: calibration, telemetry, time resolution, viewing geometry and propagation introduce uncertainty. Reading the original source helps explain why two apparently similar plots may not match perfectly. Before using it to decide whether to go outside, determine whether you are looking at an observation, a derived product or a forecast. It is a simple distinction, but it radically changes what the plot means.
How to interpret it without oversimplifying
A scientific instrument does not automatically produce a forecast: it produces a measurement, image or model that must be interpreted. Parker Solar Probe becomes genuinely useful only when we know what it measures, where the data are acquired and how much delay is involved.
