| The Lyrids have just peaked. These are fast meteors (~48 km/s) but sometimes they produce bright fireballs leaving a glowing trail lasting several seconds.
Here's a couple from the past two nights:

| The nights are no longer completely dark anywhere in Norway, but we still record some meteors against the bright sky. Here's what we've got so far in May:

| Apparently, for the moment, we have 2 moons. One as our main moon, the other is 2016 H 03. Here's a picture of the surface:
I also added it in in SE:
this moon will eventually escape though.

| midtskogen, ohh wow! nice picture! so i succeed to watch 2 in 40 minutes!
and its impressive for light polluted town like mine. also dust from the desert.
in norway i guess its much more clear and beautiful.
the problem right now is that clouds coming and going away so you cant watch it in row

| Nice capture, midtskogen!
The shower's expected to peak tonight at 13:00-15:30 UTC. That's a bit after sunrise for me, but close enough. I'll plan to watch it. Now the question is... do I watch from my home where there's more light pollution, but clear skies forecast, or go to the mountains where it's dark, but partly cloudy forecast?

| What happens when a 1km wide pure ice comet hits the earth in the Saharan desert?

| steeljaw354, well when it enter the atmosphere some of it will melt. but we talking about 1 kilometer so some if not most of it will survive. but the impact itself will be super hot, so if your question is if the desert will be covered in ice, the answer is no.
wats, go to the mountains!! it may not be clear but its gonna be worth it!!
now when i live its cloudy, imagine cloudy+pollution and i still got to see 2 of them allready!!
take the risk and go to the mountains! ^_^
edit: just saw 5 more in 20 minutes!! and there is tomorrow night too!!
gonna be awesome if sky will be clear

| How would it impact humanity? Will humanity survive?

| Quote steeljaw354 (  ) What happens when a 1km wide pure ice comet hits the earth in the Saharan desert?
http://impact.ese.ic.ac.uk/ImpactEffects/
It would be a pretty big event -- about one in a million years. Radiation from the fireball would be lethal to a couple hundred km. Seismic shaking and ejecta reach even farther. The sound of the blast would be heard across Europe.
Quote steeljaw354 ( ) How would it impact humanity? Will humanity survive?
Absolutely. There'd be some short term climatic effects, but nothing too serious. This isn't even approaching the scale of the dinosuar-killer. A plus is that if it hits the Sahara, there's not much nearby vegetation to spread fire and smoke.
There would probably be a lot of desert glass.

| Didn't expect that from a big ice cube, was expecting it to melt or vaporize, I was thinking something 100% pure water ice would just appear out of no where and fall to earth.

| Lol, not a chance. Think of the kinetic energy of that much mass moving that quickly -- over a hundred thousand megatons of TNT! And it reaches the ground just seconds after hitting the top of atmosphere.

| A friend and I drove around for a couple hours and saw quite a few streaks in the sky. Didn't take any pictures or anything though, sadly night got cut short when the clouds rolled in.
