Sitting on the balcony, facing west. I thought I saw a pinprick of white light at the edge of my vision.
I looked in that direction and about half a minute later there was another. They were pinhead size, and bright white in intensity, and lasted only a fraction of a second. Shortly after that there was a further flash of light, again for a fraction of a second, but this was much larger, about a quarter of an inch across.
The sky was light enough to have seen an airplane or helicopter, and I neither saw nor heard anything.
Sighting lasted about one minute.
