Helio replied to the thread Hopes dim for another bright October comet after Tsuchinshan-ATLAS.Tonight's image with iPhone. I give my visual of it only a 60% chance that I saw it. -

Yes, skyglow is narrow, could easily be filtered out. Arequipa had 500,000 people but all streetlights were sodium vapor. Mercury... -

Very nice image. You have some real clear skies. In 1986, I was excited to be at 10,000 feet in the Andes because I figured the skies...

Helio replied to the thread Hopes dim for another bright October comet after Tsuchinshan-ATLAS.Thanks. I just notice that Venus is barely on the left edge (about 1/2 way up). Perhaps this will help others for tonight's viewing...

Helio replied to the thread Hopes dim for another bright October comet after Tsuchinshan-ATLAS.Here's one with my iPhone. I first found the comet using the iPhone, which sees such things better than the eye, of course.

Helio replied to the thread Hopes dim for another bright October comet after Tsuchinshan-ATLAS.Ug. Cosmic particles producing sky glow?

Helio replied to the thread Hopes dim for another bright October comet after Tsuchinshan-ATLAS.Massive binocs! For Halley’s, we travelled 2 hours to a ranch. I was using Saturn to set the focus on the 8” SCT when it quickly began...

Helio replied to the thread Hopes dim for another bright October comet after Tsuchinshan-ATLAS.We could just barely see it at sunset. The camera, of course, did better.

Helio reacted to Unclear Engineer's post in the thread We have the satellite data to show climate change is real. Now what? with Like.
The actual system of chemicals transported around the planet, into and out of the ground by subduction, volcanism, etc, is quite...

Helio replied to the thread We have the satellite data to show climate change is real. Now what?.Yes. Thanks. That graph illustrates the possible difference between association and causation. Although higher temperatures are...

Helio, What I am saying about CO2 having a causal effect on warming is based on looking at the CO2 concentrations for hundreds of...

Helio reacted to Unclear Engineer's post in the thread We have the satellite data to show climate change is real. Now what? with Like.
Yes, atmospheric concentration of CO2 seems to lag a bit, compared to temperature. Many things have been shown to release more CO2...

Helio replied to the thread We have the satellite data to show climate change is real. Now what?.But even these earlier cycles don't show CO2 increase as causal to temperature increase. Or am I wrong? I'm not saying the increase by...

Helio replied to the thread We have the satellite data to show climate change is real. Now what?.The climate debate is too often a dichotomy -- for or against. This is a poor approach to it since it is a scientific topic. Science...

Helio replied to the thread We have the satellite data to show climate change is real. Now what?.That's what I think should happen and for everyone's sake. More understandable science for the public is best, IMO. The lack of this...
