 DONKI: View SW Activity
Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2023-11-05T11:45Z ( DSCOVR: PLASMAG )
All Detecting Spacecrafts:
DSCOVR: PLASMAG
ACE: SWEPAM
ACE: MAG
Activity ID: 2023-11-05T11:45:00-IPS-001 (version 7)
Quality of ICME Signature: 2 (clear signatures)
Note: A sharp temporary jump in total magnetic field to 44 nT from an already elevated 20 nT (after CME arrival four hours prior), accompanied by a jump in solar wind speed from 400 to 520 km/s; ion density remained high after the previous arrival in the morning. Further review of this arrival signature in consultation with Lan Jian at NASA/GSFC suggests that there are multiple flux ropes due to strong B compression and large-scale (in terms of magnitude) magnetic field rotations on 2023-11-05 and 2023-11-06. This complex event may be combined with the arrival of CME: 2023-11-02T03:36Z associated with CME arrival with ID 2023-11-05T08:10:00-IPS-001 in DONKI and an SIR preceding a coronal hole high speed stream detected at DSCOVR around 2023-11-06T11:47Z. Of the 2 candidate CMEs, simulation results of CME: 2023-11-05T08:10Z gave predicted arrival signature characteristics most similar to the start of this IPS. The arrival was also detected at STEREO A around 2023-11-05T12:35Z.
