Mark,

Is the writing inside the atlas in English?

I am awaiting my copy.

Opened up the mail box and what was there, a white package with a small book. I looked at the writing and address as II was not expecting anything today and for the life of me I could not figure out what language it was. My name and address was correct but the return baffled me. Then I realized it was that Mars pocket atlas and the language was Hungarian. Now if I recall Hungarian is totally unique and it's origins are a bit obscure.

Anyways, what a nice little pocket atlas. It is quite thorough. If you have ordered one and not seen it yet I think you will be surprised how good it is. This will be a nice guide at the telescope in a couple of years! Until then I should keep it in it's wrapper.

Re: Light Pollution

Ted Forte
 

Blue light is the current problem in the lighting industry and it sort of snuck up on many dark sky advocates.

Here in my county, we entered the fray a half dozen years ago when the question of legalizing digital signs (Electronic Message Centers) was being considered. We fought hard to establish a CCT of 3000k as a standard and 2500k as a target. It mostly worked. It's at least in all the new codes. Enforcement is a different story, but at least the attempt is there.

Our major victory concerned the nighttime brightness of electronic signs. These signs are capable of producing a brightness of 10,000 NITS and we won concessions from the county where we got them limited to 200 NITS and the city of Sierra Vista where they are limited to 100 NITS ( a "Nit" being equal to 1 candela per square meter). Amazingly, the science shows that you need be only 30 nits brighter than the surroundings to appear "bright" to the human eye.

But the LED revolution has really ushered in a rush to bluer and bluer light. All is not lost though - properly designed fixtures can still mitigate the effect. We have a string of new street lights in front of our hospital and I would guess that if we measured, they would be too blue to pass muster, but they are no problem at all because of their full cutoff design. Approaching the sting of lights, you can't see the fixtures at all until you are right under them. The street is brightly lit, but there is no glare and no up-lighting. Very well done.

New LED installations appear to use daylight temperature colors in the 5,000 Kelvin range which are blue white to the human eye. Downtown Norfolk has replaced all it’s antique lamp posts with LED bulbs. All blue white, bright, and with no hoods! What night sky I had is gone and the glare is terrible.

Solar Report

The sun has been quiet for some years now but5 it seems slowly coming to life. There is a large prominence on the Sun today of good intensity. Not much surface detail though. Transparency and seeing is pretty good in the cool morning. Expect it to decrease as the atmosphere heats up later in the day.

My friend JD Maddy caught it a couple of nights ago while imaging M49!  

 

I observed it (with a 30-inch at 300x) on the evening of April 2, and it was very obvious.  I estimated it at around 14.5 mag but I think it is rapidly brightening and should get to mag 13 or brighter.

Nice!  And I’ll bet you’re just waiting until the new SN in IC3322A brightens to get it too.  Thanks -

Light Pollution

jimcoble2000
 

I was just speaking with Stan and he raised an interesting point which I had not considered. As I was speaking about the increasing light pollution Stan asked if I had noticed that with the advent of LED lighting the color of light pollution has changed for a dull fish belly yellow to a much brighter blueish white. He may be right now that I think of it. Anyone else noticed this?

Hey Jim, if you think ants are cool E.O. Wilson wrote a delightful book on ants called Tales from the Ant World. Well worth the read ... Cheers Ian

How they pull that off is interesting 🕶️
