However, the prediction of the arrival of CMEs still remains a challenge. We have developed an interplanetary scintillation (IPS) estimation system based on a global magnetohydrodynamic (MHD) simulation of the inner heliosphere to predict the arrival time of CMEs. In this system, the initial speed of a CME is roughly derived from white light coronagraph observations. Then, the propagation of the CME is calculated by a global MHD simulation. The IPS response is estimated by the three-","authors_text":"Daikou Shiota, Kazumasa Iwai, Kenichi Fujiki, Mitsue Den, Munetoshi Tokumaru, Y\\^uki Kubo","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2019-03-28T03:07:34Z","title":"Development of a coronal mass ejection arrival time forecasting system using interplanetary scintillation observations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.11769","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:f7f4bb32b700dcc12ed411a0d8954565be2dcd3beb18bc13a671575b412c1d81","target":"record","created_at":"2026-05-17T23:48:29Z","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":"879fa5e569e79a4efdaf74b7789efc894b8a36bbf62afff0e83de70c7c3ef040","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2019-03-28T03:07:34Z","title_canon_sha256":"0f67e5cdd5e6a651a24a28333d3785b3d8a3b00a4e17ee1d653ada41174d88ba"},"schema_version":"1.0","source":{"id":"1903.11769","kind":"arxiv","version":1}},"canonical_sha256":"2bbadf84aea96adc03326bf4c99e64e7ec15f3f0830fa9ac9f07d6953ce19da9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2bbadf84aea96adc03326bf4c99e64e7ec15f3f0830fa9ac9f07d6953ce19da9","first_computed_at":"2026-05-17T23:48:29.689064Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:48:29.689064Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gIYv2I1JLdYc3TowqHgS/v4lF/ijnQdCE1/JE9a7sqggFVnw7sRFbGrOmIVdFflxg/MYWqRH5loU68O8OJo8AQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:48:29.689648Z","signed_message":"canonical_sha256_bytes"},"source_id":"1903.11769","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f7f4bb32b700dcc12ed411a0d8954565be2dcd3beb18bc13a671575b412c1d81","sha256:1806f87218a8bf178bc34190e6ff2772a293ab296cce3715d2822cc66ad49098"],"state_sha256":"02fc41be2dcba02fdc6bde65714106a74e3e03a18f6b46f359bc9a872915f1b3"}
