Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2023-03-15T03:48Z ( DSCOVR: PLASMAG ) Quality of ICME Signature: 1 (lacks some signatures) Note: Increase in B_total from 8 nT to 22.5 nT, reaching a maximum of 26 nT at 2023-03-15T05:02Z. Accompanied by an increase in speed from approximately 420 km/s to 550 km/s, an increase in density, and increase in temperature. The arrival could be attributed to a predicted glancing blow from either the 2023-03-12T19:24Z CME or the 2023-03-13T10:53Z (more likely the latter due to the earlier arrival at STEREO A). LASSOS team discussion summary about this signature: this is likely a strong glancing blow from a CME, with a sheath and a shock-like structure. Submitted on 2023-04-25T16:50Z by Anna Chulaki A Notification with ID 20230315-AL-001 was sent on 2023-03-15T12:21Z |
