| Zusammenfassung |
| We present preliminary results from a 24-hour run to observe meteors conducted at EISCAT (Tromsø, Norway) on 17-18 December 2009, when no strong meteor showers were active. These pertain to the single-beam echoes detected at zenith by the Tromsø VHF and UHF systems and are compared with similar results obtained in 2008 during the peak of the Geminid meteor shower (Brosch et al. 2009). We present statistics of the echoes and concentrate, in particular, on the population of high-altitude echoes defined as being at 150-km altitude or higher, and on decelerating meteors.
We also report on the character of tristatic echoes detected during the same period around 100-km altitude using the UHF receiver stations at Kiruna (Sweden) and Sodankylä (Finland), and on some low-altitude trails detected during this run.
