Abstract: A summary of the activity of the CAMS-BeNeLux network during the month of December 2023 is presented. This month we collected a total of 24353 meteors resulting in 3176 orbits.

 

Introduction

In December the Earth crosses dust of the Geminids, one of the highlights of meteor observing. Some nice minor showers are visible too. Combined with high sporadic activity this is a very attractive month for all meteor observers.

After the disappointing month of November, we hoped for better circumstances this month.

 

December 2024 statistics

December 2024 was, like last year, a somber month. Only a handful of complete clear nights occurred in large parts of the BeNeLux, France, Engeland, Germany and Denmark. And although the number of cameras and stations increased significantly compared with December months in the past, we have captured only 3176 orbits, resulting from 24353 recorded meteors.

In 8 nights, we could capture no orbit at all, and there were only a small number of nights in which we could collect more than 200 orbits. So, a meager result this year. See Figure 1 and Table 1.

Figure 1 – Comparing December 2024 to previous months of December 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.

Around the Geminid maximum the central parts of the Netherlands got no sunshine at all for a period of 11 days in a row (December 9 – 19).

So, members from this stream could only be recorded by some stations in southern Belgium and Engeland, that had some clear nights in that time.

The highest number of orbits in one night was captured in December 26–27 and December 27–28, approximately 330 and 420 orbits each night. As said earlier, compared with December 2023, the number of stations, and consequently the number of active cameras, has increased significantly (see Figure 1).

This month, only 43% of all simultaneous meteors were captured by more than two stations. This confirms the bad weather this month.

On average, nearly 117 cameras at 49 stations were active during this month. Every night, at least 111 cameras captured meteors. The highest number of active cameras was 125 for a single night. These numbers are significantly higher than last year (Figure 1).

Unfortunately, the number of orbits was hampered by bad weather.

Conclusion

Results for December 2024 are, when compared to other years, only modest, although the number of cameras increased significantly.
