Visibility III / V
Again, it’s the time of year when the Sun travels behind the orbit of geostationary satellites (or actually the satellites orbit the Sun). Each satellite transmitting at 10-11 GHz appears in the Hankasalmi radio telescope's solar observation as a pulse lasting about 5 minutes. Today, about 30 satellites were drawn into the picture. The larger pits are the trees in front of the Sun. The blue and purple lines are temperature measurements.
