Bingo! You've found one, thanks! I also noticed that in your Astronomy.com link it says "*Most researchers agree that a* **full-fledged meteor storm** *— defined as 1,000 meteors an hour or more — will occur in 2018. Draconids are slow-moving meteors, encountering Earth at less than 12 miles (20 km) per second, and they typically are faint.*"

Effect #3 is sometimes called the "bugs on the windshield" effect, because Earth is like a car moving fast, and meteors are like insects that get splattered. Of course you get more bugs being splattered on the piece of glass that's facing forward.

@FlorinAndrei I did not know that name, thank you :) and the analogy gives a nice visualization. I will include it in my answer.

Reading that the [Leonids](https://en.wikipedia.org/wiki/Leonids) meteor shower is almost upon us, I clicked some links (e.g. [EarthSky.org](http://earthsky.org/astronomy-essentials/everything-you-need-to-know-leonid-meteor-shower) and [NatGeo](https://news.nationalgeographic.com/2017/11/how-to-see-leonid-meteor-shower-skywatching-space-science/)) to read more of the prediction; especially the part about when to best view them.

I had a [Déjà vu](https://en.wikipedia.org/wiki/D%C3%A9j%C3%A0_vu) when I saw "early morning hours" because it seemed to me that "that's what they always say".

I'm guessing that it's not a coincidence that the constellation for which the shower is named always seems to rise around or after midnight at the time of year when the shower occurs.

So I'd like to ask if this is true, that they pretty much always are best viewed after midnight (except when issues of weather or the Moon interfere), and if there has ever been a shower where this wasn't the case — one that was best viewed *before midnight*.
