any standardized measurement?

25'. Does that mean we'll be enveloped or not ?

:teotwin:

not really...

Just a major space event...

btw...Those au numbers...might be wrong...

0.0214 au...might be 0.214 au...

Still waiting on Tony from spaceweather.com

I had Comet 17P image comparing Dia Arch next to Earth, when 17P was at @ 17 Dia arch on Oct 31st, 2007...on my site...lost data...sorry...I hope you where able to see it, before it was taken out..???

Kent had it on his site, but its not there anymore...

It gave reader a idea...what dia arc looks like...next to Earth...

If data from GLP is wrong, about 0.0214 au...no problems

but if data is right, and if MOID data from jpl is right...then we wait and see...what this Comet is going to do...I am concerned , about it breaking apart like many other had done before, when they come close to planet, moon...sun

That Gas cloud is hugh...that surrounds central coma...

Waiting on data...on how far that clouds extends outward?

big difference...

We still have @ 29 days to go...

Still no tail observed as of yet...

Definition/Description for SBDB Parameter/Field

Description: Earth MOID (Minimum Orbit Intersection Distance)

AS Of today... 0.0176002 au

----

5/5...BAA data...The miss distance for the orbits is 0.0178 AU and the earth passes this point 27.5 days later. Maximum is likely on August 21.9 or 27.5, with a radiant of 168 -15.

5/8....0.0176002 AU

5/5....0.0178 AU

===

But 3D orbit shows different numbers...

which one is correct????

===

New numbers...from 3D orbit...

WAS 0.214 au...closest...now 5/8/08...at 0.211au...closest...

-0.003 au...in a couple of days...not much, but still fact to the matter is...just got alittle closer...

WE need more eyes, telescopes on this comet...and better close-ups in the days to come...

Highlights

New comet 2008 J2 (Beshore) may reach binocular brightness for southern hemisphere observers around the time of perihelion. It will be a fading object of around 10th magnitude by the time it is visible from the UK. It has become quite unusual for two such relatively bright comets to be discovered in quick succession, although neither was quite bright enough for likely discovery by visual search means.

2007 W1 has brightened quite rapidly, though part of this is due to using smaller instruments. If it is sustained, the comet could reach 2nd magnitude. Although bright enough to be seen in binoculars, it is large and diffuse, so that UK observers will find it a difficult target as it is quite low down, at less than 15 degrees altitude for most of the UK.

Cedric Bemer points out the possibility of a meteor shower from 2007 W1 (Boattini). The miss distance for the orbits is 0.0178 AU and the earth passes this point 27.5 days later. Maximum is likely on August 21.9 or 27.5, with a radiant of 168 -15.

That is a great pic. I would suspect debries behind it if there is no tail to see right now. What's that other little blip in the lower left?
