Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2024-05-11T20:30Z ( ACE: MAG ) Quality of ICME Signature: 0 (weak signatures) Note: This arrival signature is characterized by a weak rotation of magnetic field components, with Btotal reaching a maximum of 15nT. A subsequent increase in speed is observed from ~770 km/s at 2024-05-11T22:30Z to 1005 km/s at 2024-05-12T00:555Z. A sharp increase in temperature is observed at this time as well. Density appears to decrease preceding this arrival signature. This is not a straightforward arrival signature, but it is possible this is a flank impact/glancing blow arrival from CME: 2024-05-09T18:23Z. Due to the increase in solar wind speed a coronal hole high speed stream may also be embedded in this signature, originating from a coronal hole which reached the central meridian on 2024-05-03.
