Contribution

It provides a comprehensive meteor database with detailed parameters and color information, enhancing the understanding of meteor characteristics and observational capabilities.

Findings

Detected over 90,000 meteors in 1.5 years

Recorded meteors with durations from 0.1 to 2.5 seconds

Analyzed color variations along meteor trails

Abstract

Here we report on the results of meteor observations with 9-channel Mini-MegaTORTORA (MMT-9) wide-field optical monitoring system with high temporal resolution. During first 1.5 years of operation more than 90 thousands of meteors have been detected, at a rate of 300-350 per night, with durations from 0.1 to 2.5 seconds and angular velocities up to 38 degrees per second. The faintest detected meteors has the peak brightness about 10 mag, while the majority - from 4 to 8 mag. Some of the meteors have been observed in BVR filters simultaneously. Color variations along the trail for them are determined. All parameters of detected meteors are published online. The database also includes the information on 10 thousands meteors detected by our previous FAVOR camera in 2006-2009 years.
