Explanation
The showers have been highlighted in terms of their visibility from your geographic location (see latitude and longitude above), according to this schema:
| Colour schema | Major shower |

The meaning of the columns is the following:
- Shower: the name of the shower.
- Interval: interval of shower activity.
- Maximum: Date of maximum activity.
- R.A. and Decl.: ICRS Right ascension and declination of radiant at maximum. Radiants with a clear positive declination are only seen from northern hemisphere, or the southern when negative.
- Vg: Geocentric velocity in km/s.
- ZHR: Zenith Hourly Rate. The greatest number of meteors that an observer would see in ideal conditions, with totally clear skies and the radiant at zenith.
- Moon %: Percentage of illumination of the Moon at 0h UTC of the maximum's day.
