Geminids 2019 Backscatter Data

By Trevor Clifton

Pictured below is the backscatter data for the 24 hour period covering the Geminid maximum.

Some of the gaps in the data is due to high levels of RF interference which although the meteor data is logged in a text file its not printed on the graph as it may be unreliable.

Arietids Backscatter Data

By Trevor Clifton

A daytime meteor shower occurs on the morning of the 7th June. Known as the Daytime Arietids, this shower is linked to the sun grazing comet 96P/Machholz. Detectable only by radar backscatter, the Arietids produces a level of activity comparable to that of the Perseids.

The activity graph is produced below and is obtained via my automated system. The missing bar at around 7 am is due to a high level of interference which causes my system to reject that 10 minutes block of data.

Lyrids Backscatter Data

By Trevor Clifton

The Lyrids may have been clouded out for visual observers, but Trevor managed to spot them using backscatter detection with his radio antenna.

The bar charts are produced in real time and a sample of the data log is attached.The first two bar charts show the run up to the event giving the background rate and the third the event itself.

Perseids Data

By Trevor Clifton

Given the sharp rise and fall the timings would suggest that the Earth travelled some 315,000 miles while in the debris stream from the comet.
It will be interesting to see if this figure changes next year.

Each bar in the chart is the meteor count for 10 minutes. 824 recorded for the 24 hours before and 1103 for the main day.
