2013 Space Weather Discussion

[venture]

Finally some stuff to talk about this year that'll be neat, so time to resurrect this old thread.

Some details on up coming near Earth Asteroids...

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.


On February 5, 2013 there were

1376
potentially hazardous asteroids.

Recent & Upcoming Earth-asteroid encounters:

Asteroid	Date(UT)	Miss Distance	Size
1999 HA2	Feb 5	58 LD	1.3 km
2013 BA74	Feb 6	4.5 LD	41 m
2013 BS45	Feb 12	4.9 LD	30 m
3752 Camillo	Feb 12	57.5 LD	3.4 km
2013 BV15	Feb 13	3.7 LD	59 m
1999 YK5	Feb 15	49.1 LD	2.1 km
2012 DA14	Feb 15	0.09 LD	58 m
2009 AV	Feb 25	59.7 LD	1.0 km
2007 EO88	Mar 18	4.4 LD	23 m
1993 UC	Mar 20	49 LD	3.8 km
1997 AP10	Mar 28	45.9 LD	1.8 km
2010 GM23	Apr 13	3.9 LD	50 m
2005 NZ6	Apr 29	24.9 LD	1.3 km
2001 DQ8	Apr 30	74.3 LD	1.1 km

Notes: LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. MAG is the visual magnitude of the asteroid on the date of closest approach.

So the one thing to point out, is that on Feb 15th, Asteroid 2012 DA14 will pass roughly 20,000 miles from the surface of the earth. From what I've read this will be the closest pass we've had in quite some time.

Also going on right now, though not visible to us until April, is Comet Lemmon is getting brighter. The Southern Hemisphere has been getting a good show for about a month now.

I've been looking forward to this NEO!!!!!!

Cool thread

Thanks Venture. I appreciate the science you enlighten us with. Please keep it up!

Plu's CME seems to have happened. LOL

EARTH-DIRECTED ERUPTION: The magnetic canopy of decaying sunspot AR1667 erupted this morning (Feb. 6th @ 00:21 UT), producing a C9-class solar flare and hurling a coronal mass ejection into space. According to first-look images from NASA's STEREO-B spacecraft, the CME appears to be heading in the general direction of Earth. If so, the likely time of arrival would be Feb. 8-9. Stay tuned for updated forecasts.

and I'll bet Oklahoma will get the worst of it. lol ^ ^

Mercury will be visible tonight just before sunset to the west. It'll be pink with twilight blue around it.

Another CME occurred today and will possible deal a glancing blow to the earth, so those north of us should get a good light show from the auroras.

Asteroid 2012 DA14 had its size increased to 60m as it gets closer. Still expected to miss us by 17,000 miles, which is good. It's size would deal a blow to leave a crater roughly twice the size of OKC. That would be a bad day.

I went outside and looked but couldn't see it for some strange reason.

Oh yeah, those darn clouds and fog. LOL

2012 DA14 up to 62m now. Getting a better look as it gets closer obviously.

That's absolutely insane...especially those last two videos. Its especially crazy to ask why the guy in that first video was filming in the first place! I mean, what are the chances! SMH beyond belief...

Most people in Russia have dashcams because of insurance fraud and police corruption. People jump in front of cars all the time over there so they can make some money off of their injuries.

This one is incredible. Boom happens at 0:11. Turn down volume!

I wonder if this is any relation to 2012 DA14? If not, what a huge coincidence!

[dmoor82]

Will the event be able to be seen by eye?What time?

BADASS!!!!!!!!!! I would've loved to have been there! Man why does all the crazy sh*t happen in Russia? lol... It's been said the world has became cooler since video cameras were introduced there lol

ESA said it was not related.

We run into an average of around 100 tones of space debris per day.
