“…139.73 ± 0.03 to the fireball, its atmospheric trajectory and heliocentric orbit were calculated (Table 1) with very high precision 1 . The same event was also recorded by the digital video camera system MAIA (Koten et al 2011;Vítek et al 2016) deployed at the Kunžak station (λ = 15 • 12 E; ϕ = 49 • 6 N, altitude = 652 m). This camera records digital video at 61.15 frames per second in 10 bits of the signal depth, and provides a circular field of view (FOV) with a diameter of about 50 • .…”

Context. A bright fireball was observed above the Czech Republic on September 9, 2016, at 23:06:59 UT. Moreover, the video cameras at two different stations recorded eight fainter meteors flying on parallel atmospheric trajectories within less than 2 s. All the meteors belong to the September epsilon Perseid meteor shower. The measured proximity of all meteors during a very low activity meteor shower suggests that a cluster of meteors was observed. Aims. The goal of the paper is first to determine whether this event was a random occurrence or a real meteor cluster and second, if it was a cluster, to determine the epoch and at what distance from the Earth the separation of the particles occurred. Methods. The atmospheric trajectories of the observed meteors, masses, and relative distances of individual particles were determined using a double-station observation. According to the distances and masses of the particles, the most probable distance and time of fragmentation is determined. Results. The observed group of meteors is interpreted as the result of the orbital fragmentation of a bigger meteoroid. The fragmentation happened no earlier than 2 or 3 days before the encounter with the Earth at a distance smaller than ∼0.08 AU from the Earth.

Meteor recording, detection, and analysis is one of the traditional topics of astronomy. This paper deals with fast-tracking of faint meteors and meteor showers in video sequences with high frame rates. Since meteors are fast optical events, the utilization of cameras with high frame rates and short exposure times is the standard technique of meteor tracks capture. Low efficiency of such camera systems is typically compensated with image intensifiers, mostly based on the microchannel plate (MCP). In this work, we use image data captured with the meteor automatic imager and analyzer, double-station system dedicated for observing faint meteor showers.The system works with minimal human interaction, and it is necessary to automatically process (i.e., identify all meteor candidates) all captured data as fast as possible.Results show possible speed-up of the image processing method when fluctuations of MCP are reduced.

“…For the purpose of this paper, testing data were acquired with the system MAIA (Meteor Automatic Imager and Analyzer) [ 45 ]. This system uses image intensifier XX1332 and GigE (Gigabit Ethernet) progressive scanning camera JAI CM-040GE, running at a frame rate of 61 fps and a bit depth of 10 bits.…”

The automatic observation of the night sky through wide-angle video systems with the aim of detecting meteor and fireballs is currently among routine astronomical observations. The observation is usually done in multi-station or network mode, so it is possible to estimate the direction and the speed of the body flight. The high velocity of the meteorite flying through the atmosphere determines the important features of the camera systems, namely the high frame rate. Thanks to high frame rates, such imaging systems produce a large amount of data, of which only a small fragment has scientific potential. This paper focuses on methods for the real-time detection of fast moving objects in the video sequences recorded by intensified TV systems with frame rates of about 60 frames per second. The goal of our effort is to remove all unnecessary data during the daytime and make free hard-drive capacity for the next observation. The processing of data from the MAIA (Meteor Automatic Imager and Analyzer) system is demonstrated in the paper.
