Meteor and Atmospheric Object Observations Database on Kyiv Comet Station (MPC Code 585): 15.06.2025 - 22.09.2025

This dataset contains records of 240 meteor events observed during a focused monitoring campaign. Period: The monitoring observations were conducted over 99 nights from June 15, 2025, to September 22, 2025, independent of atmospheric conditions. Target Area: The camera was directed towards a segment of the sky centered at horizontal coordinates: Azimuth 284∘, Altitude 56∘. The objective provided a 72∘×54∘ field of view. Data Format: The primary database is stored in an Access file format and is supplemented by video and image files. Limitations: The observation period concluded due to prolonged cloudy weather and scheduled/emergency power outages. The 240 recorded meteor events include: Video clips in AVI format (duration 2-3 seconds, covering one second before and one second after the event). Video resolution: 640×480 pixels at 30 frames per second (fps). Video file size: 1.8 to 5.5 MB. Frames per clip: 61 to 88 frames. Integrated Images: A corresponding JPG image generated by stacking all frames of the meteor passage. The monitoring station consisted of a camera, a computer with a video capture device, and a photocell relay system for automated operation. Camera: Monochromatic WATEC-902H CCD camera (1/2′′ matrix, sensitivity 0.0003 lux, resolution 570 TVL) housed in a weatherproof, thermo-regulated box with a 5W heating element. Optics: Camera objective with a relative aperture of 1.3 and an 80∘ field of view. Automatic Iris Control: The camera's auto-iris was externally powered (5V) and regulated by a photocell relay. This system ensured the lens remained closed during the day (to protect the sensor) and automatically opened when ambient illumination dropped below a certain threshold. Data Capture and Processing: A computer (Intel Core2duo, WinXP) used an AverMedia PCI TV-tuner (BT878 chip) as a video grabber. The HandyAvi ver.4.3B software processed the video stream, automatically saving video fragments and integrated JPG images upon detection of a moving object against a dark background. System time was synchronized via an NTP server using timememo.
