Visibility III / V
To the beginning of our nature trip, a confusing observation in the morning sky in Laukaa 12.1. at 8.03:
Multiple consecutive flashes in the sky caused by solar reflections apparently on the same orbit
The total duration of the observation from the beginning to the end is about 10 s, about 10 flashes in a row, the phenomena of the Iridium satellite type flash occurred at regular intervals and on the same orbit, at the same time visible max. two flashes. The duration of each flash may be on the order of more than a second. The advancing motion of the flashing objects is a type of satellite motion, the direction is clearly visible during the flash. The brightnesses of the flashes are the same, in the order of the Arcturus star, which is estimated to be visible in the sky.
The orbital direction indicated by the flashes in the sky is about NNW-SSE, the height is roughly about 60 degrees.
The weather is perfectly clear, with the brightest stars visible in the morning.
Other observers are Ari Pirkkalainen, Arto Stenroos and Timo Äijänen.
(At our request on January 14, Ursan Leo Wikholm has identified the cause of the phenomenon as ten Iridium satellites flying in a row)
