Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2023-08-07T11:07Z ( DSCOVR: PLASMAG ) Quality of ICME Signature: 0 (weak signatures) Note: A somewhat unclear arrival signature, affected by low quality solar wind data from both DSCOVR and ACE during this time period. There is an initial increase in B_total from 7.4 nT to 10.5 nT, followed by another increase to 13.6 nT at 11:54Z. The signature looks like a messy sheath arrival and it is possible that there is a flux rope/magnetic cloud at ~2023-08-08T01Z but this could be another CME arrival (LASSOS team). The current arrival may also have been observed at STEREO A around 2023-08-07T08:46Z.
