This 'LINEAR' C/2012 X1 was discovered after C/2012 S1 - i.e., ISON. 'S' vs. 'X'. This 'LINEAR' (and there are a lot of comets discovered by LINEAR) is still in the asteroid belt. It will not make perihelion till February 21, 2014. So it is trailing ISON by 3 months.
Cbet nr. 3676, issued on 2013, October 22, announces the discovery of a new comet (discovery magnitude ~18.8) by M. Schwartz on CCD images obtained with the 0.41-m f/3.75 Tenagra III astrograph. The new comet has been designated P/2013 T2 (SCHWARTZ).
We performed follow-up measurements of this object, while it was still on the neocp. Stacking of 16 R-filtered exposures, 50-sec each, obtained remotely from MPC code F65 (Faulkes Telescope North) on 2013, October 16.4 through a 2.0-m f/10.0 Ritchey-Chretien + CCD (operated by Las Cumbres Observatory Global Telescope Network), shows that this object is a comet: sharp central condensation surrounded by a coma about 6" in diameter.

M.P.E.C. 2013-U18 (including prediscovery Catalina Sky Survey data from Sept. 14.4 UT, when the magnitude was given as 17.8-18.6) assigns the following elliptical orbital elements to comet P/2013 T2: T 2013 June 20.65; e= 0.53; Peri. = 342.52; q = 1.60; Incl.= 9.36

The huge meteorite chunk split into three pieces when scientists tried to weigh it. The precise weight could not be established because the heavy object broke the scales.
"The preliminary examination... shows that this is really a fraction of the Chelyabinsk meteorite. It's got thick burn-off, the rust is clearly seen and it's got a big number of indents. This chunk is most probably one of the top ten biggest meteorite fragments ever found," said Sergey Zamozdra, associate professor of Chelyabinsk State University, as cited by Interfax news agency.
He explained that it was important to establish the weight of the fragment in order to learn more about the qualities of the whole of the meteorite.
The lifted chunk was taken to the regional natural history museum. The plan is to have a small sample of it X-rayed to determine what minerals it consists of.
A state of the art satellite is being sent into space to monitor the blind zone between the Earth and the sun to warn of incoming asteroids.
Astronomers have previously not been able to spot asteroids in the 'blind zone' due to radiation from the sun blocking information.
But now The European Space Agency intends to launch the Gaia Space Telescope with its key task being to monitor the area between the Earth and the sun and warn of any impending collisions.
One recent asteroid which could have been spotted as it travelled through the 'blind zone' months before it collided with the Earth, was that of the Russian asteroid of February this year which caused a spectacular fireball before smashing into Chelyabinsk, 900 miles east of Russia.
Gerry Gilmore, professor of experimental philosophy at Cambridge University's Institute of Astronomy told the Sunday Times: "Gaia will measure all the asteroids including those between us and the sun which are the really nasty ones because we can't see them."

Cbet No. 3674, issued on 2013 October 21, reports an outburst in brightness of comet C/2012 X1 (LINEAR). The magnitude of the comet was measured by H. Sato on on Oct. 20.5 to be total mag 8.5 (as measured within a circular aperture of diameter 85".2) with a brighter center about 10" across. The predicted H_10 magnitude for C/2012 X1 (LINEAR) would be around 14 now.
We performed follow-up measurements of this object on 2013 October 21.51. Below you can see our image of this comet, stacking of 3x20-seconds unfiltered exposures, obtained remotely from MPC code H06 (iTelescope Observatory, New Mexico) through a 0.50-m f/6.8 astrograph + CCD + f/4.5 focal reducer. At the moment of the imaging session, the comet was just +16 degree above the horizon and the Sun was -11 degree. Click on it for a bigger version.
Below you can see an elaboration of the original image with the MCM filter. This filter creates an artificial coma, based on the photometry of the original image, and subtract the original image itself in order to highlight the internal zones of different brightness that are very close to the inner core and that would normally be hidden from the diffuse glow of the comet.

Now scientists are reporting the discovery of a river monster, Arapaima leptosoma, in Brazil's Amazonas State. It's a new species, described from a single specimen measuring 33 inches from head to tail, in a genus that can grow to almost 10 feet and weigh up to 440 pounds.
Arapaima, also commonly known as pirarucu, is a genus of air-breathing fish that inhabit creeks and backwaters in and around the Amazon basin. They live by crushing other fish between their large bony tongue and the roof of the mouth. People prize them both for their tasty flesh and for their handsome scales, which tourists (including this writer) used to carry home incorporated in handsome necklaces and other folk art. But these huge fish are now badly overharvested, in part because it's so easy to harpoon them when they come to surface to breathe. Arapaima gigas, for example, is listed as endangered under the Conventional on International Trade in Endangered Species, or CITES.

This trend toward a future of autonomous fleets of large-scale war fighters is developing in tandem with the trend toward miniaturization and the mimicking of nature itself to hide drone tech in plain sight.
The latest developments focus on ways to not only get new drone models aloft via remote control, or through their own autonomous decisions, but how to keep them there for as long as possible - perhaps even permanently.
