Summary of Activity for September Perseids

In 2018 a total of 19 cameras contributed data to the UKMON repository. Together, these cameras recorded 384 individual meteor observations for September Perseids. The number of recorded observations by station is as follows:

After applying quality criteria`we found that 32 meteors were observed by more than one camera (Unified observations). The following shows a count of the number of meters observed by two, three, etc. cameras.

The number of unified observations as a percentage of individual observations is 8.3%.

Fireball Ativity

A total of 0 fireballs were observed in the reporting period. Here we define a fireball as a meteor event with a magnitude of -4 or less.

Velocity Distribution

The following graphs show the distribution of velocities


The following graphs show the distribution of magnitudes:

The following plots shows the altitude of the atart and end of ablation for each individual meteor. The plot is in order of decreasing start height and gives a good visualisation of the depth of the ablation zone. Where in the atmosphere ablation occurs will depend on factors such as meteor velocity and composition.

The maximum observed altitude was 115.157524 km and the minimum observed altitude was 78.399963 km. The distribution of distances travelled through the ablation zone was as follows:
