Fading

Comet Lemmon, you are going to have to take my word for it!

C/2025 A6 (Lemmon) is quickly fading from view. Since it was clear Willow and I thought we would give it one more go to spot it.

This time I took my 20mm wide angle lens knowing that if the comet could be seen it would appear very small in the photos. This is the lens I am most comfortable using for night photography because it gives such a large view of the sky. It also allows me longer exposures before the stars streak.

The sun went down and the full moon came up behind us. It dipped quickly to -4°c, which felt chilly. I am going to have to toughen up if I plan on making it through winter. We walked around where Slinky and Ara are buried. It is truly a beautiful spot. As the sky turned blue and darkened we spotted flashes of white as we jumped several White Tailed Deer. They were quick not to stick around. It reminded me of hunting with Dad. Seeing the best game when it was too dark to shoot. Both because you couldn’t see the far sight on the rifle, and more importantly, it’s against regulations.

The full moon illuminated the mountainside. Only the brightest stars could be seen. Of course, the moon also washed away the comet. Still I had faith and pointed the camera in the general direction of where it should be.

Moonlit night.

Both Willow and I were glad to get back to the warmth of the truck. We picked our way along the back rounds, through frozen puddles, staying the best we could above the ruts. Such a pleasure in my life to putter along old and overgrown roads. I used to do it with a beer in my right hand, now it’s a coffee if anything. We stopped at the lake. It was calm and the moonlight reflected the mountains. I listened for fish jumping. Willow heard something and gave a bark. Her echo barked back at her and then the barking match was on. Willow looked at me seriously, ‘there is another dog out here’.

Time to head back to the valley bottom and the warmth of bed.

Comet Hunting

Tried to peek through the clouds to get a glimpse at Comet Lemmon. It hasn’t been easy with clouds rolling in just as it’s been getting dark, however thought I’d give it a try regardless. You’ll never catch fish if you don’t put your line in the water.

As the clouds parted I was able to easily see the comets nucleus. In the photo you can even see it reflected in the river. The tail was harder to see. The camera picked it up nicely even amongst the light pollution of the Village of Radium Hot Springs.

Just a word about light pollution; it was interesting to have been in Waterton recently and saw how they have tried to limit light pollution. They are part of a dark sky reserve and it is important to them. In the Windermere Valley light pollution gets brought up occasionally but never gets much traction. The only way it ever will is by showing decision makers that there is some profit in shining lights down. That is a tough sell in a valley growing as fast as this one.

Speaking of pollution, notice the ‘scratches’ in the sky around Comet Lemmon. These are Starlink satellites. It is amazing and annoying how many are in low orbit around the earth. It is almost impossible to look into a darkened sky without seeing them now. This is only going to get worse as Starlink continues to launch thousands more and other countries and companies begin to launch their own version of Starlink.

Without regulations or common sense it may become impossible, in the future, to enjoy the stars, meteor showers and visiting comets, as the night sky fills with streaking satellites. Humans should be ashamed of polluting the atmosphere, oceans, water and land, instead of giving it a second thought, however, we have moved onto corrupting the space and stars above us.

I would still like to get a better look at Comet Lemmon, but my chances are limited as it gets closer to the sun and our weather fails to improve.

Nice brisk morning at -6°c. Willow and I went out at about 5:30. It was just starting to lighten around the mountains in the east. The waning moon was bright to the southeast. I pointed the camera in the direction of where Comet Lemmon should be located as I wasn’t able to spot it with my naked eye. Later when I was home I was able to easily locate it on the downloaded photos. Now that I know where to look it will be easy to spot next time out. And it should get brighter!
