pi-Puppids 2011: prediction of activity


Fig. 1. Space-temporal projection of pi-Puppids trails parts onto their minimal distance passages dirung the period 22.01.2010-22.07.2012 (correspondence between colours of the particles and their ejection velocities can be seen here).

No encounters with trails are found. Activity is not expected.
