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.
