+# Supernova Peak Predictor
+Predicts **when** and **how bright** a supernova will become from early ZTF observations.
+
+## Novel Contribution  
+First model to predict `days_to_peak` and `peakmag` as regression targets from rise-phase alerts.
+
+## Architecture
+ConvNeXt-pico (Galaxy Zoo pretrained) + 23-feature metadata MLP -> fusion -> dual regression heads  
+8,811,816 params (8,425,576 trainable)
+
+## Test Results
+| Metric | days_to_peak | peakmag |
+|--------|-------------|---------|
+| MAE | 124.03 days | 0.324 mag |
+| Median AE | 29.15 days | 0.223 mag |
+
+## Data
+[MultimodalUniverse/btsbot](https://huggingface.co/datasets/MultimodalUniverse/btsbot) — rise-phase supernovae only  
+3x63x63 image triplets + 23 metadata features. Leaky features (age, days_since_peak) excluded.
