Why it matters at 0.75–5 µm
Sits in SPHEREx's deep north ecliptic pole field, which is observed far more often than the average sky.

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.
