Abstract: A summary of the activity of the CAMS-BeNeLux network during the month of August 2023 is presented. This month was good for 43080 multi-station meteors resulting in 12074 orbits.

 

Introduction

In August, of course, all attention goes to the Perseid meteor shower, peaking around August 12. Little moonlight this year in the first half of the month offered favorable conditions. It was going to be a very successful month.

August 2024 statistics

The month of August was by far the sunniest and warmest summer month in 2024. Since the start of CAMS in 2012, it has only been sunnier in August in 2022. But even the less sunny days were often followed by a (partially) clear night this month. There was not a single night this month without simultaneous meteors. This has happened before since the start of this project in the BeNeLux, but never before have the lowest scores in one night been so high during an entire month. Only in two nights did we collect less than 100 orbits: 80 orbits in the night of August 3–4 and 31 orbits in the night of August 17–18. More than 1000 orbits were collected in 5 nights (August 5–6 and in all nights from August 9–12). The nights around the Perseid maximum were the highlights when 2761 (August 11–12) and 2882 orbits (August 12–13) were collected under clear sky conditions.

All cameras in CAMS-BeNeLux captured a total of 133634 meteors this month. Of these, 69684 were simultaneous. In the end, this resulted in a total of no less than 18522 orbits. This is by far the best result for August since 2012 (Figure 1 and Table 1). 59.7% of all orbits were collected from more than two stations.

The blue bars represent the number of orbits, the red bars the maximum number of cameras capturing in a single night, the green bars the average number of cameras capturing per night and the yellow bars the minimum number of cameras.

Part of this great result is also due to a significant expansion of our network with stations in the East of England. Seven RMS cameras in this country started to provide camera data to our project. Nick Russell (Seaford, UK), and Alan Maunder (Catherington, UK) started their contributions with 1 and 2 RMS cameras respectively on August 9. Nick James (Chelsford, UK) delivers his data to our network since August 11. Jamie Olver (Redhill, UK) since August 12. Steve Carter (Welwyn Garden City, UK) made his first contributions on August 16. Finally, contributions by Miles Eddowes (Reading, UK) are available since August 20. Together with data of the other UK cameras of Andy Washington and Jim Rowe, who are contributing already for several months, these stations have already contributed to a total of 1992 simultaneous meteors during the month of August. In the Netherlands, Rob Smeenk placed another RMS-camera in Assen on August 11. The number of captured meteors by this camera is already considerable: no less than 910 meteors of his total number of meteors this month were simultaneous.

The atmosphere over the southwest of the Netherlands is now better covered with cameras, since the station in Oostkapelle unfortunately stopped running, at least for some months, in June. The cameras of Steve Rau (Zillebeke, Belgium) have also been switched off since 23 August due to renovation work. Restart of these cameras will probably follow in November.

During the Perseid maximum, we were also treated to the activity of a new meteor shower. Peter Jenniskens called this new meteoroid stream the ‘nu Capricornids’ (Jenniskens, 2024a; 2024b). CAMS-BeNeLux collected no less than 19 meteor orbits of this new meteoroid stream. On average, 124 cameras were active every night this month. This high number is of course also a result of the expansion of our network this month. A minimum of 118 cameras and a maximum of 131 cameras were active each night
(Figure 1 and Table 1).

Conclusion

In August 2024 we have captured a record number of meteors, resulting in a new record of orbits for this month, thanks to excellent weather and a significant expansion of our network, especially in the United Kingdom.
