Timing analysis between HXRs, radio bursts, and in situ electrons.
| Event | Onset time | Emission time | Energy | Method for |
|---|---|---|---|---|
| at observer (UT) | at the Sun (UT) | injection time | ||
| HXR I | 12:05 | 12:02 | 15–25 keV | – |
| Type III | 12:13 | 12:11 | – | – |
| Type II | 12:21 | 12:13 | – | – |
| HXR II | 12:17 | 12:14 | 15–25 keV | – |
| Electrons (SolO/EPT+HET) | 12:22 ( * ) | 12 : 16 ± 1 min | 35−39 keV ( * ) | VDA L = 0.29 ± 0.06 AU |
Notes. The emission time at the Sun for particles represents the injection time estimated using the VDA method, where L is the inferred propagation path length. The emission time at the Sun in the case of the radio bursts and HXRs refers to the time when these are emitted at the Sun taking into account the light-travel time to Solar Orbiter (∼2 min and 5 sec) and Earth (∼8 min and 20 s), respectively. The asterisk in the last row indicates the energy ranges at which the SEP onset times have been estimated. The events are ordered chronologically based on their emission time at the Sun.
