Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2024-07-02T23:41Z ( ACE: MAG ) Quality of ICME Signature: 1 (lacks some signatures) Note: Start of a series of complex arrival signatures seen at L1. Start of very small increase in B-total from 3nT to 4.6nT seen starting at 2024-07-02T23:41Z, with corresponding rotation of B-field components. B-total begins to steadily increase over the next several hours until reaching a peak value of 6.41nT at 2024-07-03T15:30Z. A corresponding steady rotation of B-field components progresses over several hours until 2024-07-03T15:30Z. Temperature steadily decreases from about 80 K at 2024-07-02T22:38Z to about 50 K at 2024-07-02T23:41Z. Temperature shows a sudden increase at 2024-07-03T15:46Z, reaching about 130 K. Density remains very low, around 2cc, until 2024-07-03T15:30Z when it begins to slowly but steadily increase. This arrival is currently suspected to be the combined arrival of the filament eruption CME:2024-06-29T16:12Z and the glancing blow arrival of CME:2024-06-29T04:00Z. Analysis is ongoing.
