Blue (Starlink) satellite?

I captured these images last night while my cameras were on patrol for Lyrids meteors.

They appear to show a blue satellite trail around 9:19PM Mountain Daylight Time, as seen from the Sacramento mountains of southern New Mexico.

Note that camera's color balance was set to 'daylight' and in the first image another, fainter, satellite trail is also visible...it's not blue, it's a typical color. Also note star colors. This camera over the years has shown itself to be accurate in rendering color in night/day photos.

Have others seen this before?

Sony a6300 camera, 23mm lens at f/1.4, ISO 800, 30 second exposures, using intervalometer with 31-second timing. Camera pointed near zenith. (Note that this lens, at f/1.4, shows stars with coma and astigmatism in the corners of the frame...so the stars look as if they have wings/tails.)

First image of blue satellite trail. Camera is pointed near the zenith.

Lyrids meteor shower: post-peak report from the Sacramento mountains of southern New Mexico.

I set up two cameras on tripods with wide angle lenses, set the intervalometers to take 30-second exposures...went to bed...cameras kept going until almost 3AM before the batteries exhausted. Almost a thousand images.

I only captured a few Lyrids. Most were close to the shower radiant, which means they were short meteors...didn't cover much sky.

Please note the alt-text on the images. The first two images are of a non-Lyrid meteor that was interesting.

If you have images of star fields, but are "Lost in Space"...upload your images to:
nova.astrometry.net/

This meteor is not a Lyrid. Why? Extend the path...and it comes nowhere close to Lyra. But it's the brightest meteor I captured...at the edge of the frame, so optical quality is poor. The next image is the same piece of sky, but five minutes later...
The meteor trail is still faintly visible after five minutes. It's a squiggly line, distorted by very high altitude winds.
This long meteor does appear to be a Lyrid because an extension of the path points toward the shower radiant. Where in the sky is this? Do you recognize the star field? See the next image...
Here's the cheat sheet, after the image has been matched to known stars...called astrometry.

The Eta Aquariids are the debris left by a comet called 1P/Halley, or Halley's Comet, which comes around every 76 years. Its radiant is close to the constellation of Aquarius, which will present a strong showing for the southern hemisphere, with up to 50 to 60 meteors per hour.

🚨 Meteor Alert 🚨

... starting on April 20 and finishing up on May 21, with a peak on May 2 to 3, the Eta Aquariids will light up the southern tropics.
..
Neither meteor shower will require any special equipment. All you need is somewhere comfy, a clear view of the sky, your own two eyes, and the willpower to get out of bed in time to see it.

According to AMS, The annual Quadrantids meteor shower, which is active between 26 Dec and 16 Jan, is expected to peak on 03 Jan at around 17h45 UT. This peak favours the Pacific Ocean region.

Hiroshi Ogawa (Japan) predicts a peak on 04 Jan at 09h UT, so bear in mind these variances between predictions. Personally, I trust the latter.

The shower has a traditionally sharp peak of activity over a few hours, but if the timing is out then other parts of the world will get the benefit of the peak activity. The new moon on 30 Dec will help with darker skies.

Hiroshi Ogawa and Hirofumi Sugimoto Abstract: The Quadrantids 2024 showed a much higher activity than on average during past years. The peak was recorded with AL = 8.3 ± 1.3 and a ZHRr = 226 ± 5 at λʘ = 283.04°– 283.17° (2024 January 4, 6h30m – 9h30m UT). Also, a sub-peak has been observed after the main peak which reached AL = 7.4 ± 1.1 and a ZHRr = 135 ± 14 at λʘ = 283.43°– 283.55° (2024 January 4, 15h30m – 18h30m UT). As a result, this activity has been observed separately as two components, one was the regular activity which had AL = 8.5 at λʘ = 283.13° and the other was a sub-peak with AL = 6.5 at λʘ = 283.47°. The enhanced regular activity such as in 2024 has been also observed in the past. On the other hand, however, a strong sub-peak after the main peak has never been observed in past.
