Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2022-07-18T20:40Z ( DSCOVR: PLASMAG ) Quality of ICME Signature: 1 (lacks some signatures) Note: Magnetic amplification accompanied by a jump on solar wind speed and density. Some time later (2022-07019T04:00Z)there is a drop in temperature and a change of magnetic component pattern to a more smooth one, probably indicating the arrival of magnetic cloud. Btotal reached a peak of over 16 nT at 2022-07-19T00:23Z. This looks more like a flank impact of a CME. The notification was sent out for an earlier time (2022-07-18T12:47Z) since the signature is very complex. Submitted on 2022-07-20T14:32Z by Anna Chulaki A Notification with ID 20220718-AL-003 was sent on 2022-07-18T17:31Z |
