DONKI: View SW Activity
Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2021-03-26T21:35Z ( DSCOVR: PLASMAG )
All Detecting Spacecrafts:
DSCOVR: PLASMAG
ACE: SWEPAM
ACE: MAG
Activity ID: 2021-03-26T21:35:00-IPS-001 (version 6)
Quality of ICME Signature: 0 (weak signatures)
Note: CME signature is not clear and it may be combined with a stream interaction region. Arrival time was difficult to select. We discussed it with GSFC ICME experts for clarification. From Dr. Lan Jian: There is a magnetic obstacle from Mar 26 21:35 to Mar 27 14:40, characterized by some non-smooth field rotations, increased B, declining speed, and low Tp. I selected the boundaries based on the sharp changes of total B, but there are boundary layers at its two sides. After it, there is a stream interaction region, in which the “fast” wind speed is not that fast (less than 450 km/s), and the stream interface is at 22:48 on Mar 27.
