However, FRB 200428 is 4 to 8 orders of magnitude less energetic than the typical population of cosmological FRBs. This discrepancy is likely due to the moderate magnetic field strength and evolved age of SGR 1935+2154. In contrast, newborn extragalactic magnetars, such as those formed in gamma-ray burst (GRB) central engines, are expected to have much stronger magnetic fields, more rapid spin-down, and highly dynamic magnetospheres, all of which favor the production of brighter and more frequent FRBs.\nWe propose a targeted search for FRBs from the recently localized GRB 230307A, a long-duration GRB with evidence suggesting the formation of a young magnetar. Given the source's relatively close distance (291 Mpc) and possible youth (less than 3 years), it offers a compelling opportunity to test FRB generation mechanisms during the early evolution of a magnetar.\nWe request 30 hours of observing time with the Parkes 64-m Murriyang telescope using the ultra-wideband low-frequency (UWL) receiver. Our plan includes one 10-hour long-duration session to detect rare or clustered bursts, and ten 2-hour sessions spread over 2-3 months to sample temporal variability. Data will be processed with state-of-the-art pipelines for single-pulse searches and coherent dedispersion.\nA detection would strongly support magnetar-origin FRB models and provide key constraints on the early-time activity of GRB-formed neutron stars.", "num_resources": 0, "num_tags": 0, "organization": {"id": "aa2e8465-918a-44d1-aaab-34b7632fa3e5", "name": "csiro-data-access-portal", "title": "CSIRO Data Access Portal", "type": "organization", "description": "Harvester for CSIRO Data Access Portal", "image_url": "", "created": "2025-06-23T12:29:12.193044", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://data.csiro.au", "href": "https://data.csiro.au/collection/csiro:69479", "title": "CSIRO DAP"}, "owner_org": "aa2e8465-918a-44d1-aaab-34b7632fa3e5", "private": false, "promotion_level": "0", "spatial": "Australia", "state": "active", "temporal_coverage_from": "2000-01-01 00:00:00", "title": "Parkes observations for project P1380 semester 2025OCTS_07", "type": "dataset", "unpublished": false, "url": null, "version": null, "resources": [], "tags": [], "groups": [], "relationships_as_subject": [], "relationships_as_object": [], "extras": [{"key": "harvest_object_id", "value": "b714e116-40bc-4722-822c-1e7ad8f23135"}, {"key": "harvest_source_id", "value": "74e2544e-7627-4cb4-b9ba-1d4a043af4f3"}, {"key": "harvest_source_title", "value": "CSIRO DAP"}]}}
