Global light pollution survey.

There is a global light pollution survey running from February 21 to March 6 and then from March 22 to April 4. Basically, it consists of estimating limiting magnitude using the Orion Constellation and Leo for the second survey starting in late March and submitting details online.

The current run has very few submissions from Ireland, so maybe if you have time you could click the link below and have a look? Estimates can be backdated if you have the records.

Added data for Belfast. I'll do the same for Lurgan (Armagh) over the weekend if I get a chance.

This sounds interesting. I must look at that link and keep it in mind next time I am out.

Posted Data for Monasterevin Co. Kildare for last night. I am moving much closer to Dublin (Lucan) over the next 2 weeks so I expect to see a significant deterioration
I will post Data for that location also.
