Meteor seen in Portugal
- perihelions 2y agoI had the luck to see one these in person—an absolutely brilliant fireball in sparking white. Maybe if I reorganize my flow to spend more hours outside in the evenings I can fool statistics into showing me a second one.
- sebastiennight 2y agoAh, the good old mathematical law num_lifetime_meteor_sightings = tan(pi * n/48) Where n= daily hours spent outside looking at the sky
- perihelions 2y agoIt's fucking up my equation to continue investigating this, but, shouldn't this be a simple Poisson distribution (constant rate)? What model are you doing that has a trigonometric tan
- scarmig 2y agoI think it's a joke; imagine you spent 24 hours a day looking at the sky.

- sebastiennight 2y agoIt was a joke. I just wanted a function with f(0)=0 and a nice vertical asymptote at f(24). Sorry for the headache!
- genman 2y agoJust i.e. almost a day ago.
- matosinhos 2y agoI saw this last night in Matosinhos - north Portugal outside of Porto. This is a town that happened to have its biggest celebration of the year last night. It's called Festas do Senhor de Matosinhos. The meteor made an appearance 15 minutes before midnight. The big fireworks were to go off at midnight. We all thought it was the weirdest firework we'd ever seen and only later realized it was a meteor. It was truly huge. And lit the ground blue. The really interesting part of this is that the festival is to celebrate a miracle in the town wherein a vision of Jesus appeared a long time ago. I am not religious. But wow. Quite a coincidence. Posting under a fresh account for location privacy, of course. Maybe this sounds unbelievable but here is the program of the festival where you can see that the fireworks happen: https://www.leca-palmeira.com/senhor-de-matosinhos-4/ https://www.leca-palmeira.com/senhor-de-matosinhos-4/ And here's the wiki about the reason for the festival: https://pt.wikipedia.org/wiki/Matosinhos#Etnografia https://pt.wikipedia.org/wiki/Matosinhos#Etnografia

- samaritano 2y agooh no, now every believer will start seeing god's plan everywhere...
- SllX 2y agoYou should have seen chat in NASA’s YouTube stream during the recent total solar eclipse.
- narag 2y agoTime ago there was a running joke about YouTube comments sillyness. That section has improved a lot. Live chats, on the other hand... During a recent volcano eruption someone was convinced that the rain would help stop the lava. I can't forget that. Oh, and the prophetic, blessings, I knew it, climate change, etc.
- agile-gift0262 2y agoMy first thought seeing the video: wow, I'd love to see something like that in person. Immediate second though: so grateful for our atmosphere
- DrNosferatu 2y agoIt was quite sensational: It was cloudy over me, so no bolide - I only saw slowly rising to 100% saturation brightness outside, during pitch-black night. (sonic boom a couple of minutes later). I gave it a 20% chance it was a nuke from Putin :D
- O5vYtytb 2y agoI saw one like this 15 years ago. It was terrifying as I was alone in a forested area and I had no idea what it was at first. But then the sonic boom that lasted for minutes was even more disconcerting.
- csours 2y agoDid you hear about that restaurant they opened on the Earth? The food is mid, but GREAT atmosphere.
- devsda 2y agoMy first thought was similar like how incredible it would be to experience it in person. Second thought was, if we see this in a movie it might come across as your average cgi scene (without any epic music or slow shots) and doesn't standout much. But now that I know it is real, all these normal videos (compared to movie CGI) somehow makes them better, special and makes me want to be there which doesn't happen with a movie scene.

- franky47 2y agoSolar eclipse, auroras, and now a meteor: space weather has been a lot of fun lately.
- xattt 2y agoIs the rule of threes now fulfilled, or is there still more to come? I’m personally hoping for a daylight-visible supernova before the end of 2024. I’ll mention that the population in my region appears to have stayed primed to watch astronomical phenomena since the eclipse. The beach I usually go to for viewing was busier the night of the auroras than some beach days in the summer.
- Cyphase 2y agoI'm glad I'm not the only one who thinks about daylight-visible supernovas. Come on, Antares or Betelgeuse! Not a daylight-visible supernova, but a naked-eye night-visible nova is expected to happen later this year: https://www.space.com/new-star-night-sky-nova-explosion-rare https://www.space.com/new-star-night-sky-nova-explosion-rare
- jerome-jh 2y agoNext year +/-10k years ;)
- throwup238 2y ago> Is the rule of threes now fulfilled, or is there still more to come? Usually it means a change in the ruling dynasty of China. Or so they say...
- Ma8ee 2y agoMaybe Iran this time?
- thaumasiotes 2y agoDoes this mean we're looking at a restoration of the dynastic system?

- TheBlight 2y ago>travelling at roughly 28 miles per second. That's (~45 km/s) pretty close to the Sun's escape velocity from Earth (~42 km/s). I wonder if there's a chance it's interstellar.
- belter 2y agoLet's hope it's the only fragment. Interstellar objects come fast, unexpected, and out of NASA current tracking...
- TheBlight 2y agoIt was definitely moving fast. After a quick browse, only 2 other fireballs were moving at least that fast in the CNEOS catalog (https://cneos.jpl.nasa.gov/fireballs/ https://cneos.jpl.nasa.gov/fireballs/). It would be interesting to know its velocity components. Hopefully NASA will have and report that data.
- jojobas 2y ago42km/s is assuming you use all of Earth's orbital velocity (~30km/s) to your favor, a small deviation means 45km/s won't cut it. In terms of possible angles, it's a very low chance of an interstellar object.

- fanf2 2y agoThis is the IMO Fireball report: the event happened about 24h ago https://fireballs.imo.net/members/imo_view/event/2024/2481 https://fireballs.imo.net/members/imo_view/event/2024/2481
- qprofyeh 2y agoThey finally sent someone to stop the invention of AGI.
- falcor84 2y agoYou mean like Kyle Reese?
- 0xB31B1B 2y agoAll of these interesting space phenomena on film in the past 10 years and the most recent video of “alien activity” I saw came out in like 2005. I don’t think they’re here.
- HeyLaughingBoy 2y agoThis was an alien spaceship that miscalculated the entry trajectory and burned up in the atmosphere.
- mharig 2y agoFor sure Trolls who escaped the disc world.
- Rapzid 2y agoAny estimates on the mass yet? 100,800 mph and it didn't disintegrate immediately.. Wowzers.
- Towaway69 2y agoDid any of the large space agency predict this? I.e. Was the object actually detected before impact?

- bentpins 2y agoI was curious whether handling them directly is a good idea. There's some guidance here: https://ares.jsc.nasa.gov/meteorite-falls/how-to-handle-meteorites/ https://ares.jsc.nasa.gov/meteorite-falls/how-to-handle-mete... Try not to handle any freshly fallen meteorites with your bare hands! Oils and microbes from your skin will slowly degrade the surface of a meteorite, dulling the fusion crust, contaminating the meteorite, and promoting rust. The contamination aspect is especially important for carbonaceous meteorites and other uncommon types.
- TacticalCoder 2y agoThat's good news: if there's already one fragment that's been found, there are probably many!
- peddling-brink 2y agoI’m no expert, but that looks like asphalt.
- bilsbie 2y agoEven if a miracle happens and we get to net zero, warming and extreme events like this will continue for decades due to climate lag and feedbacks.
- jhugo 2y agoIt’s a fragment of a comet that came from very far away from Earth. How do you think it’s related to climate change?
- deleted 2y ago[deleted]
- AlexDragusin 2y ago> The relative contribution of the main emission lines of iron, magnesium and sodium control the color of meteors, which emission (colour) predominates is related to the meteor's composition and velocity; fast meteors (>30 km per second) ionize magnesium and are green, moderate velocity meteors (30-15km per second) ionize iron and are blue, and slow moving meteors (<15km per second) ionize sodium and are yellow-orange.
- admissionsguy 2y agoThen the triffids came.
- SwiftyBug 2y agoI know this is completely irrational and very very unlikely to happen, but one of the greatest fears I have when flying is that the plane will be hit by something like this.
- nicklecompte 2y agoIf I had to die in a plane crash, this seems like the least terrifying way to go out. Way better than hearing an ominous rumbling, scrambling for the oxygen masks…
- ta1243 2y agoThat's like trying to hit a bullet with a smaller bullet, whilst wearing a blindfold, riding a horse.
- deleted 2y ago[deleted]
- short_sells_poo 2y agoAny space expert able to explain the very vivid blue colour please? I distinctly remember most meteors are either white or greenish tinted. Was it just the composition, or was it down to higher temperatures reached due to the higher speed?
- mendigou 2y agoI was lucky enough to see this one live. It was astounding. It became day for a few seconds and then it broke off into a half dozen pieces or so. It left an incandescent trail behind. It looked incredibly close. I had the feeling we were going to hear it coming down nearby in a few seconds, but it ended up in the Atlantic Ocean (actually not that far from us since we were by the ocean, but far enough). So glad we were having drinks outside and I wasn't grabbing anything in the house!
- sph 2y agoLooking at the reaction of the girl in the video, I wondered... when you see something out of the ordinary like that, do you get the ape/lizard brain instinct of "oh shit the sky is on fire, better hide under a rock"? I have seen enough meteors in video to recognise one in real life, but I wonder if for a split second the fight-flight instinct kicks in before reason prevails.
- mendigou 2y agoIndeed there was a split second of primal flight response, and then awe. Not like you have a long time to think about it!
