Regarding ‘light trespass’ (Alex Pratt May 14), I agree that astronomers are not generally seen ‘normal’ people. That said, I have spoken to a couple of my neighbours over the years about their outdoor lighting shining into my upstairs windows. Both responded fairly positively and the situation improved, including my views of the night sky.
Literally today I responded to a local planning application for a new house that included potential ‘security’ lighting. Good that it would be activated by a motion sensor, but I felt the following comments were worth making.
‘Security’ lighting will be operated by ‘intruder switching’ (as stated, which is good) but should also be directed so as to illuminate this property alone. It should not shine onto neighbouring properties, where it would present an obtrusive light nuisance, or onto the public highway (from where the property would be visible), where it would present a hazard by shining into user’s eyes.

Hi Tony, thanks for the info. It seems the ‘old’ Krakow database would be a good place to data mine if it were available! A shame if the data is not used, not everyone will have submitted it to the AAVSO. I take your point about publishing them in the BAAVSS circular, they are fundamental results that should be readily available. (I’ve got a secondary min of UV Leo from last night, I’ll probably submit that to the circular.) Hopefully Krakow will go live again in the not too distant future.
Last night I noticed that Kreiner/Krakow are no longer accepting data submissions via their website. Their ‘old’ data is still accessible. I don’t know why this has changed. Atlas of O-C Diagrams of Eclipsing Binary Stars (up.krakow.pl)
