>Why are some showers removed from the observing lists?
Hi Kevin, sorry for the late reply as this one was buried...
Some "showers" have been removed as the others have mentioned, but you
might also look at it as some showers not being "advertised" anymore. In
the case of NAMN, I maintain a larger shower list than I publish. Instead
we work off the IMO list since it contains showers that have activity
detectable by visual means.
It is also possible that some showers exhibit a variability that results in
removal from working lists...but might need to be re-instated later.
