Did anyone see Halley's comet in 1986? I was 9 years old and I remember my dad going out early in the morning to try to see it through his rifle scope but I don't think he ever did. You couldn't get as much good advice about when and where to look as you can now. I'll be 84 next time it comes around if I make it that long. I am lucky enough to live in a great place to look at stars.
I was a boy living in the UK then. Glad my parents took my out one clear night with some binoculars to see it. I remember the trail well. I also remember trying to figure out how old I'd be when I saw it next and realising I'd be "old as hell".

If I had children, I would try to get them to see these things even if it meant a short trip as it often is a once in a lifetime experience, and at least if they aren't dumbasses, it will leave an impression.

Just saw this over SW North Dakota. I thought it must be a starlink train but it looks like they haven't launched since Monday. Anyone know what it could be or should I be posting in the paranormal thread?

Download Stellarium free to your phone and point. It'll tell you if they are starlink or other satellites I think. I know for sure it shows Starlinks, just don't know if it has them all catalogued or how long after they launch.

Could be China's Spacesail network that they are launching to compete with Starlink (or to try to force their internet rules on more people).

It didnt break up, its still a single body with a jet pointing toward the sun

This raises a new anomaly of 3I/ATLAS that must be explained by those who wish to shove the anomalies of 3I/ATLAS under the carpet of traditional knowledge on solar system comets rather than consider alternatives. As Albert Einstein said: “Knowledge is realizing that the street is one way; wisdom is looking in both directions anyway.”

Technological thrusters which point their exhaust towards the Sun would accelerate away from the Sun. This post-perihelion maneuver might be employed by a spacecraft that aims to gain speed rather than slow down through the gravitational assist from the Sun.

That really does look like a Starlink train. They usually disperse into the grid shortly after launch... Maybe another company or country with an unannounced sat grid? Interesting at least.
