This evening I was surprised to see a line of these satellites rising from the south-west horizon starting at around 18:10 and continuing for at least 10 minutes. On reaching the zenith they disappeared into the earth's shadow one by one. Looking through my 30x80 binoculars (not easy to hold by hand!) they were bright points of light with a golden hue - at first I thought they may have been Chinese lanterns but clearly they were not! The total number was in the order of 30 or so and not equally spaced, some flying very close together as a pair. Never seen anything like this before in many years of observing the night sky so can only presume these are Elon Musk's Starlink satellites! A bit concerning if there are many more to follow!
