Sorry curious/nosey .Besides it does my head in every time I look out of window or stand doing washing up .

My neighbour has a revolving reflector in their chimney - it is bright chrome/ steel and, when the sun is in the right position it can reflect this like a strobe light. Could it be that? (not my neighbours, of course, but yours...)

Could be ...? But not really sunny today . And never seen it before .Though guess reduced tree canopy might be partly a factor .
