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.

I have been asked if I could publish a “normal” non meteor shower period so comparisons can be made to the Perseids so attached is one I did recently. The bar chart covers 24 hours 22:00 to 22:00 and each bar count covers 10 mins as before.

There are three periods where no meteors were recorded, 07:00 to 07:10, 13:30 to 13:40 and 17:20 to 17:30. Given the times its likely that GRAVES took the system offline for breakfast, lunch and tea!
