It was Monday afternoon. I went out into the garden to make some pictures with my digital camera of an approaching thunderstorm. I like to picture such events (I'm a hooby photographer). I made some pictures and later on the computer I watched these pictures and suddenly on one I saw a little white dot in the dark clouds. But it could have been anything, so I guessed. But on another picture there was it again, now closer on the left side of the picture. I was excited. As I zoomed it bigger it appeared to me to be something I never have seen before in that way. As I took the pictures I was looking north. But I haven't seen anything with my eyes. Only the clouds and the rain of the thunderstorm which was coming closer. Weird... .
