Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2023-11-20T09:49Z ( DSCOVR: PLASMAG ) Quality of ICME Signature: 2 (clear signatures) Note: Characterized by a jump in B_total from around 5.6 nT to a peak of 14.55 nT, with Bz remaining largely neutral with a short southward spike to -5 nT. An increase in density and small spike in temperature and solar wind speed to about 340 km/s are observed in tandem. This CME arrival was likely also detected several hours prior at STEREO A around 2023-11-19T16:55Z. A separate enhancement in the magnetic field components, possibly associated with the same CME event, is observed leading up to this event seen best from 2023-11-20T05:00Z onward with a gradual increase in B_total up to around 12 nT with no corresponding and associated parameter changes seen in the density, temperature, and wind speed parameters. Around 2023-11-20T09:12Z, Bt swiftly drops down to around 5-6 nT prior to this arrival. Submitted on 2023-11-20T18:34Z by Chris Stubenrauch No Notification has been sent for this activity yet. |
