Ursids 2012: prediction of activity
to the list of predictions
Fig. 1. Space-temporal projection of 6P-ids trails parts onto their minimal distance passages dirung the period (correspondence between colours of the particles and their ejection velocities can be seen here).
Fig. 2. Detailed space-temporal projection of Ursids trails parts onto their minimal distance passages in 2012 (correspondence between colours of the particles and their ejection velocities can be seen here).
No trail encounters are found for 2012, only background activity is expected.
