In the 2010 the Leonids are expected to produce the background maximum, which, by IMO's data, should occur on 17 November at 21:15 UT. Maximum ZHR is expected by IMO to be around 20, which coincides with the Author's expectations.
Significant encounters with 55P trails are not found, so the background Leonid maximum will most probably the single one in 2010, though still quite prominent comparing to other "usual" Leonid returns. As shown on the Fig 3, the sole more or less notable deflection from the red line reflecting background activity expectations is located within several hours around 2-3 UT on 19 November (formal peak time - 2:12 UT on 19 November). It is caused mainly by particles of perturbed and thin 1234 trail. Its own computed ZHRmax is only 3-4, so far, considering falling background activity this trail is not expected to form a separate activity peak, but will only be able to keep the activity at ZHR~14 during several hours. Nevetheless, considering that intensity predictions could be understated, this period of time is perhaps the most interesting to watch for any unexpected Leonid activity behaviour.
