Abstract: A summary of the activity of the CAMS-BeNeLux network during the month of April 2024 is presented. This month was good for 8566 multi-station meteors resulting in 2672 orbits.

 

1 Introduction

Meteor activity in April is still at a low level for northern latitudes. But with the Lyrids around April 22nd, we welcome the first well-known yearly meteor shower since the Quadrantids in early January.

2 April 2024 statistics

Weather in April remained very unsettled in this month. Although we could collect orbits in all nights, except during April 18–19, there were many nights with only partly clear conditions. Clear weather at all stations in the BeNeLux was, like nearly all months since October 2023 very rare.

Only in four nights we could collect more than 200 orbits: April 1–2, 21–22, 22–23 and 28–29. So at least then we benefited from better conditions. We could collect 629 orbits during the nights April 21–22 and April 22–23, mostly Lyrid meteors, as can be seen in Figure 1.

CAMS-BeNeLux captured 8566 meteors multi-station. This resulted in 2672 orbits. 51,5% of the multi-station meteors, were captured by at least 3 cameras.

On average, 116 cameras were active every night in April. A greater number than last year because the number of stations and camera is still growing in our network. This month, at Dourbes four additional RMS cameras were installed by Hervé Lamy.

Figure 2 – Comparing April 2024 to previous months of April in the CAMS-BeNeLux history. 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.

2022 27 2543 24 81 62 77.2
2023 29 2888 36 111 88 101.4
2024 29 2672 45 131 101 116.0
Total 323 23749

 

At least 101 cameras were active each night. Comparing this number with the number of archived orbits, this confirms the impression that the weather was very changeable.

3 Conclusion

This is the fourth best result compared with all other April months, especially due to a larger number of cameras in our network.
