Leonids 2016: prediction of activity to the list of predictions ![]() Fig. 1. Space-temporal projection of Leonids trails parts onto their minimal distance passages in 2015 (correspondence between colours of the particles and their ejection velocities can be seen here). ![]() Fig. 3. Assumed profile of overall Leonid activity (blue line) and its background component (red line). A usual background maximum is expected for Leonids in 2016. According to the IMO data, it occurs on the solar longitude 235.27°, in 2016 it corresponds to 10:20 UT 17 November. As observations show, in "usual" years its maximum ZHR is around 10-20. No other notable activity peaks were found. References 1. "Comet's dust 2.0" program by S. Shanov and S. Dubrovsky. [Used for orbital computations.] 2. Lyytinen E, van Flandern T.
