Leonids 2023: prediction of activity
to the list of predictions
Fig. 1. Space-temporal projection of Leonids trails parts onto their minimal distance passages in 2023 (correspondence between colours of the particles and their ejection velocities can be seen here).
Fig. 2. Assumed profile of overall Leonid activity (blue line) and its background component (red line).
No significant trail encounters are found for 2023, so far the Leonids activity is expected to be primarily formed by background component.
