Re: (meteorobs) Cloudy fireball detections!
Hi Ed and others,
Many Dutch observers have experienced this phenomenon during the 1989
Perseid maximum night, when a fireball appeared behind the clouds.
The kind of photometric detectors that used to be employed with our all-sky
network should be able to record such events (as it did, I believe, back in
1989), perhaps. Ed: for details about such PMT detectors, contact Hans
Betlem who build several of them during the eighties.
