там изображена центральная вспышка
будет покрытие Тритоном. Вы находитесь в центре полосы, можно наблюдать центральную вспышку
6 октября у вас будет покрытие Тритоном
9 июля 2022 года - на удалённом телескопе T68 (iTelescope.Net) - мне удалось сфотографировать редкое покрытие яркой звезды SAO 164648 (HIP 107569 = HD 207123) спутником Сатурна - Титаном.

The time stamp on the video corresponds to the end of the exposure of the frame. To get the time of the event, the difference between the system time and the time obtained from GPS was added and half of the frame duration was subtracted, that is, the time of the event was tied to the middle of the frame duration. The difference between the system time and the GPS time was determined with an accuracy of 2-4 ms. relative to 1PPS light flashes recorded on video. Wherein, the time difference was determined from those frames where the onset of the flash occurred at the end of the frame exposure. Such measurements were taken before and after occultation. The difference in system time and GPS time in the moment of occultation was calculated from these measurements. The time of the disappearance of the star was determined from the average signal levels of the star.
