Our light curves and color curves suggest that this event belongs to the \"normal\" class of type Ia SNe, with a decline rate parameter $\\Delta m_{15}(B) = 1.32 \\pm 0.10$, and that it suffers little extinction. Adopting a distance modulus to its host galaxy of $(m - M) = 31.89$ mag, we compute extinction-corrected peak absolute magnitudes of $M_B = -19.01$, $M_V = -19.05$, $M_R = -19.03$, and $M_I = -18.79$. The explosion occurred close enough to the nucleus of NGC"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1706.03289","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
