β Ori · HIP 24436
A luminous blue supergiant that illuminates the faint Witch Head reflection nebula.
Why it matters at 0.75–5 µm
A hot star's spectrum falls steeply across 0.75–5 µm (Rayleigh–Jeans tail) — the opposite slope to a cool brown dwarf.

Builds a 4-epoch × 102-channel input from real SPHEREx L2 exposures here (64×64 at 6.15″/px), then runs the ONNX model in your browser to pick the best viewing channels and score anomalies and motion. The first run at a position takes 1–2 minutes.
