Confirmation Images of the Near-Earth Object 2015 LF on 2015-06-07

The Near-Earth Object 2015 LF (Orbit type: Apollo ) was first observed by the Catalina Sky Survey(MPC code 703) on 2015 06 07. The asteroid has an approximate diameter of 13 m - 31 m ( ~45 foot - 102 foot) ( H=26.4) and will make a close approach to earth on 2015-Jun-08 at ~ 23:49 UT (06:49 PM CDT) at an approximate distance of 0.00131Astronomical Units ( 0.51 Lunar Distances) or 121,772.108 Miles (195,973.211 KM).

From here
Here is more info

Ok at .51 LD or 121,000 miles it of interest but sorry no DOOM PORN here today LOL
but should keep a eye on it tough sometime they do have smaller piece that tag along will have my sky cam ready if not clouded out

Your link doesn't give much info, got another one that might be more in depth? Sorry, on phone and hate searching on this.

Will we be able to see it? When and where? I'm not nit-picking your OP, just want more info as we have clear skies today and that NEVER happens when these events go down. I'm in the middle of Hellinois, so if you can find any info if we might see this it's much appreciated!

Hello all,

This looks like a close approacher, maybe a _really_ close
approacher. It should be visible from Australia/Japan/China for
several hours. By the time it gets around to Europe, it'll be
a tougher find (still possible, perhaps, but it would be nice
to get it well before then.)

yeah, the scale for condition code (accuracy of data for how close to earth) is 0 (good) thru 9 (highly uncertain), this is rated at a 7.....not good at all.

Still looking for more info here FaceBook

Look like same info

Really don't like this almost nothing on GOOGLE search
still looking

IT listed on here

Why say that and no more?

We dont all know who this Otto Matic is. Who is he?

a reply to: Trillium

it's under 50meters (good) and less than 1LD keeps it interesting, thanks for posting.
Is it just me, or did skywatchers just notice this NEO yesterday, whose closest approach is...tomorrow?

a reply to: SecretKnowledge

Not sure either but still more interested on the ball (2015 LF) not the player

Automatic?

What do you mean nothing on google search?? This place is going to have a live feed running tonight.

Later today, 8 June 2015 at 23:49 UT, the just discovered, 10 meters large asteroid 2015 LF will have an extremely close, but safe, encounter with the Earth.

This rock, discovered by the Catalina Sky Survey on June 7, will brush us coming closer than 200.000 km, that is only half of the mean lunar distance.

This small rock will peak in brightness at mag. 14.5 or so, requiring at least a 16″ scope for visual observations. Imagers can try to capture it with smallere telescopes, showing its fast apparent motion, reaching more than 0.25 deg/minute.

The condition code is an orbit uncertainty value. With 9 being the most uncertain and 1 being definite.

A value of 7 does not necessarily bode ill.

2015LH was discovered yesterday. It's closest pass is tomorrow and estimated closest distance is 120,000 km or thereabouts. No matter our uncertainty in the shape of its orbit, it won't suddenly move closer by 100's of thousands of km.

When they say lunar distance, isn't that from the center of the earth? The earth has a radius of about four thousand miles to deduct. Not that this is going to make any difference in this case, but if something was going to come within four thousand miles, it means it would hit the earth's crust and roll around.

Ya found it a few minute after I did the google screach came up on their face book page

The ephemeris for this asteroid's close approach (as seen from the centre of the Earth) shows that the asteroid's maximum apparent magnitude will only reach about 14.72, too dim to be observed in binoculars or by naked eye. 14.72 is comparable to Pluto when it's close to perihelion. You'd need a really good backyard telescope for that.

I would guess that the condition code is so high because of how few observations there are. More observations, means more accuracy and 42 is pretty low.

42 - Answer to the meaning of Life, the Universe, and Everything. There may be something to this!

So long . . . and thanks for all the fish!
