The target event was the X1.6 flare that occurred in NOAA AR 13663 at 02:22 UT on 3 May 2024. We employed a velocity-driven model, in which the photospheric velocity field was derived from the time-series magnetograms to use as the boundary input. The simulation showed a rapid increase in both thermal and kinetic energy density around the actual onset time and location of the X1.6 flare. We revealed that the flare was triggered by two-step reconnection, in which the initial tet","authors_text":"Takafumi Kaneko","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-sa/4.0/","primary_cat":"astro-ph.SR","submitted_at":"2026-06-08T08:59:25Z","title":"Predictability of a solar flare in May 2024 using observational data-driven MHD simulations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.09226","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:9d2a3094cc854b3307202f0d3266a0c8576d7f8b212d7a7fbcfd3b51a7b10af0","target":"record","created_at":"2026-06-09T02:08:08Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"89b24f47eeb748b62e1352953c5c977fc1047f8349505889bb7d913b70b112b7","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-sa/4.0/","primary_cat":"astro-ph.SR","submitted_at":"2026-06-08T08:59:25Z","title_canon_sha256":"f5551999d7f26887f954de568e15cf96e2ac83557ada26df12771d16616b4f7b"},"schema_version":"1.0","source":{"id":"2606.09226","kind":"arxiv","version":1}},"canonical_sha256":"9d68b2e63c5dcf467de1eb62af9e2001bc23a9e11f2d1854c29f5002fae35e28","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9d68b2e63c5dcf467de1eb62af9e2001bc23a9e11f2d1854c29f5002fae35e28","first_computed_at":"2026-06-09T02:08:08.515640Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-09T02:08:08.515640Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"FKuHRrbGOFRvVLFTmWYrbu8bUaZ98jom4AzdPkyACSGlhhGAhFHOG2HuKNP7oTX7Xy0rItpN3Z5GGl8O78yuCw==","signature_status":"signed_v1","signed_at":"2026-06-09T02:08:08.517079Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.09226","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9d2a3094cc854b3307202f0d3266a0c8576d7f8b212d7a7fbcfd3b51a7b10af0","sha256:8186d3fcd8ce2ccf5e5caacf3f6327d467cff1c8351fce542544e143e8af8095"],"state_sha256":"9a29af1883eb5b4bb2795b7ef0b9c2e0c33dad8dfcf2126f2ab928b6efc611c0"}
