Geostationary Satellites
When looking at the pictures I made of the planet Neptune, I noticed a couple of traces. Most probably these traces are satellties, interesting to notice is the fact the pictures shows three "satellites" 'in line'.
Weather Summary September
September was a warm and dry month with only 28 liter of rain /m2. Interesting to see is the 1 air frost day on September 30th. This is first air frost day since 2014.

The message is build around 1679 pulses of binary codes (zero and one's) and contains information about our numerical system, chemical elements, human beings, our planet, our solarsystem and the telescope itself. It was sent by the Arecibo telescope using radio signals.
