Line: 18 to 18
  Traditionally, the Leonids are a very variable phenomenon; quite different from year to year. That is the reason for the substantial disagreements among the different predictions.

  The Earth as seen from coming Leonid meteors at the moment of maximum from 1932 trail at 4:55 UT on 19th November. Red line shows the border of hemisphere where the Moon is above horizon. Image from Maslov.

The increment of meteor's activity will last for a week, however the most important maximum visible this year will happen during the early morning of the 19th November, at approximately 4:45 UT, (allow 5 minutes margin deriving from models). This maximum will be produced by the trace left behind by comet Tempel-Tuttle in 1932. Observers from western Europe will be the best situated since the radiant (the point from which shooting stars seem to come; Leo constellation in this case) will be near the zenith at the time of the maximum. Moreover, the Moon will not be a problem for observers as it will be nearly new.

 Diagram from David Asher (Armagh Observatory), where the interception of the trace left behind by the comet Tempel-Tuttle in 1932 is shown. This trail is the cause of this maximum.

There are different forecasts concerning the intensity of the maximum:
