RH323

I did mean brightness, sorry for that! I'm still pretty new to all this so I appreciate the correction. I actually did research on whether it was a fireball or bolide. They're quite fascinating really. Based on the descriptions and qualifications for what counts as one, it seems the most likely explanation. I checked for any sites where they list sightings. Unfortunately there isn't one for my country, or seemingly any reports from my country. So I checked an international one. There were many sightings on the day I viewed it but the viewing times were very far from mine, the closest one was a report from Singapore at 17:10 UT, two hours after my viewing. But based on what I've read, I do think that what I saw was a fireball or bolide. So I sincerely thank you for that suggestion and for essentially solving my mystery!

Sorry for that and the confusion, anyways thank you for the suggestion!

That seems like a perfectly valid explanation to what I saw, and likely based on what you said but would the ISS, at its speed, create a trail?

It wasn't quite that big and gassy, but I do find this very fascinating-

Zermelo, to answer your questions It was a moonless night so I can't be certain but it was roughly 10 times the size of Jupiter (viewed from the naked eye), perhaps a bit smaller than the size of the moon, when the moon is completely overhead. (like the picture below) It was visible for roughly 2-3 seconds after which, not even the trail was visible. And there wasn't a noticeable colour just a white light.

I'm fairly new and on one of my daily stargazing sessions I viewed, with the naked eye, a huge passing light going SE, from my perspective it was brighter and bigger than any stars, planets or meteors that I've seen before. It was roughly the size of a baseball. If this was a star -> . this is roughly how big it looked -> O It had a trail of similar size, seemingly dusty. It also passed and disappeared between Corona Borealis and one of Hercules' legs. Viewed on May 16th, 22:00- 23:40 I assumed, based on recent headlines, that it was Comet Swan, but upon further investigation, that was far from true. Comet Swan should not be visible with the naked eye, and definitely not to the degree I saw. Additionally, based on my coordinates* it wouldn't even cross the sky I saw, it would be below the horizon. (*roughly 15 °N, 120 °E, PH) Considering again the magnitude of the object amd the fact that I viewed it with the naked eye discounts it from being an asteroid or meteor*. (*More possible but still hard to believe with its size, you wouldn't even see something like that during meteor showers) So I then researched if it could be space debris. I thought that something as big as that should be covered by a news article somewhere. *The only results were of the 18 ton Chinese Rocket but it couldn't be that because: A. It passed over Los Angeles and New York then fell into the Atlantic Ocean, with some pieces landing in Africa. Meaning it wouldn't pass over my country. B. That happened 5 days before my viewing, on May 11 at 11:33 AM ET (08:33 PDT) It's still possible but it just seems unlikely, and with how big it was I'd assume that it would attract some media attention but I cant find anything else. Does anyone have any idea what it could have been? I have to know. If it was debris then all I need is confirmation. * https://www.google.com/amp/s/www.cnbc.com/amp/2020/05/16/chinese-rocket-falls-to-earth-space-debris-problem-worsens.html https://www.google.com/amp/s/www.theverge.com/platform/amp/2020/5/13/21256484/china-rocket-debris-africa-uncontrolled-reentry-long-march-5b
