The light doesn't fade in, the camera exposure changes. I am imaging it now, and keep having to increase the exposure to see it. If I had it set the same way as the full moon, the picture would be black.
Most amateur astronomers like to observe them. Planes are much brighter and far more likely to ruin your image. I have lots of frames ruined by planes, as well as random satellites and meteors. Iridium flares are very predicable and can be avoided.
The older Iridium satellites had 3 large, flat antennae on the bottom. These would reflect sunlight down, and if viewed at the right time and place after dark or before dawn, would go from invisible to the brightest thing in the sky for a few seconds. Since the satellites were in predictable orbits and orientation, it was possible to forecast exactly when these flares would occur. I enjoyed viewing them, and surprising people by pointing them out ahead of time. I'll miss them, since the new satellites are a completely different design.
The filter built into a DSLR would block light of that wavelength. The reason I had it removed for taking astrophotos, to get maximum red transmission. With it in place, transmission of wavelengths greater than 600nm is significantly reduced and close to zero by 1100nm. 1550nm is well into the IR band, and the longer the wavelength, the less energetic the photons. Also, the camera lens wouldn't focus it. Glass lenses are like prisms, and refract different wavelengths of light differently. Camera lenses and refractor telescopes use multiple lens elements with different refracting properties to bring red, green and blue to the same focus point. Not so with IR. If the camera was focused for visible light, IR would be out of focus.

When did Linux become a company?
Adobe Flash strikes again.
That makes no sense whatsoever.

Waiting for it to start.
For real security, go back to Token-Ring.

We have to get rid of 32 bit support to prepare for the future 128 bit systems.
One of the upgrades included space-hardened 80486s, replacing the original 80386s.
Microsoft finally caught up on the backlog.
Last Windows that doesn't bother you about updates.
Other scooters?
When your launchers can be reused 10 times, you don't need to continuously build them. Sooner or later you have enough.
The downsized employees will start their own new company called SpaceY?

Sounds like a job for Elon and the Boring Company!
Why would they slow? Without friction, they would just orbit forever. You need to transfer energy to some other object to lose orbital velocity.
Because it contains at least one unpaired electron?
No?
Year of the Linux dashboard.
Are there cars available not manufactured by corporations?
No mention of the system hacked. So how do they know they got data on some parties and not others? What system has all that data on all those people?
