Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2024-08-04T21:25Z ( ACE: MAG ) Quality of ICME Signature: 2 (clear signatures) Note: ICME arrival signature characterized by a sharp amplification of magnetic field components with Btotal increasing from the already elevated (by the previous arrival) 13nT to 20nT at 21:26Z. Simultaneous increases in solar wind speed from 368 to 416 km/s and in density to just under 14 p/cc at 21:56Z. A possible source could be CME: 2024-08-01T11:48Z. Our simulation for this CME does not show an impact at L1, but the CME could have been wider and more central than in our analysis.
