I use to have a high interest in observing sat's. Still have some.
One with a double flash period is "tiros n", could be described as per quote.
Another with a rapid single period flash is "Cosmos 1933".
There was once a failed Japanese geostat that used to fash yet remain almost stationary. I last observed this at Ilford around 1998. Haven't seen it since, yet have not been looking.
