On June 5 new white LED street lights were fitted outside my windows.
On June 6 at 3a.m. there was an extensive display of noctilucent cloud.
On June 7 at 3 a.m. there was a lesser display.
Birds began singing this morning during the display.
I normally used the Leica 8x32 BA which had excellent control of glare for these observations.
However, the surface brightness and whiteness of the new LED light is so high there was light spill/glare looking at the horizon just above the light.
This did not occur with the old light.
The 10x42 Elite is better and exhibits almost no glare here.
The AFOV of the Elite is smaller. The real field of the 10x42 Elite is 5.6 degrees the 8x32 BA 7.7 degrees.
The display looked beautiful in the 10x42 Elite with fine detail seen.
The noctilucent cloud moved faster than I have seen previously.
Close up photos of the LED lamp indicate some side shielding. Previously I asked for shielding which happened in two days for the old light, so maybe this was noted when installing the LED light.
I don't go out the front because of Covid and many passers by. So it may take a while before I can inspect the light from below.
My friend in Sweden unfortunately passed away mid March from this disease.
We spoke every two or three weeks for the past fifty years.
He seems to be a victim of Sweden's policy of non intervention and no official control of the disease.
Neighbouring countries have taken a different policy.
However, the U.K. statistics are truly awful and I avoid contact with people.
