SOTT Focus: The Cs Hit List 06: Let's Do the Planetary Twist to the Tune of the Brothers Heliopolis

OK, it's time for more weirdness. As we covered in a recent SOTT Report, accounts and recordings of strange noises heard all over the world went semi-viral on YouTube in January this year, and some are even receiving mainstream media coverage. Some YouTube pundits claim they're all faked, a couple of scientists say they're 'normal' and nothing to worry about, and many are freaking out as the phenomenon is feeding the '2012-apocalypse-oh-my-God-we're-all-gonna-die' hysteria. So what's really going on?

The hype appears to have started with these videos from Kiev, Ukraine, posted on 3 August and 11 August 2011, respectively. (Although, as we'll see later, these were not the first accounts.)



(See here for a translation of the uploader's account of the sounds and analysis and here for a summary of the associated thread, with additional analyses and accounts.)

Dozens of videos have been uploaded since then, some obviously faked, others perhaps not. For example, at least 28 videos posted in the months since Kiev obviously use the sound from the original video played over random video footage, sometimes with staged 'Oh-my-God-what-is-that?' dialogue. And, no, as far as I can tell, none of them use samples from the films Red State or War of the Worlds, as some have claimed. The similarity is striking (trumpet-like blasts, metallic rumbles and such), but truth has been known to resemble fiction. And it wouldn't be the first time that similar strange noises have been heard, both in recent times and the murky depths of history recorded in myth and legend.

New Comet: P/2012 C3 (PANSTARRS)

Cbet nr. 3021, issued on 2012, February 16, announces the discovery of a new comet (discovery magnitude 21.6) by Larry Denneau and Richard Wainscoat in four exposures taken with the 1.8-m Pan-STARRS 1 telescope at Haleakala on February 15.3. The new comet has been designated P/2012 C3 (PANSTARRS).

We performed some follow-up measurements of this object, while it was still on the neocp. Stacking of ten R-filtered exposures, 60-sec each, obtained remotely, from the Siding Spring-Faulkes Telescope South on 2012, Feb. 16.6, through a 2.0-m f/10.0 Ritchey-Chretien + CCD, shows that this object is a comet: faint fan-shaped tail, nearly 6-arcsec long in PA 284.

New Comet: C/2012 C2 (BRUENJES)

Cbet nr. 3019, issued on 2012, February 12, announces the discovery of a new comet (discovery magnitude 15.3) by Manfred Bruenjes on 30-s CCD exposures taken on two nights with a 0.36-m f/2.0 Schmidt-Cassegrain reflector on February 11.1 & 12.08. The new comet has been designated C/2012 C2 (BRUENJES).

We performed some follow-up measurements of this object, while it was still on the neocp. Co-adding of 5 unfiltered exposures, 30 seconds each, obtained remotely on 2012 Feb 12.8 through a 0.15-m f/7.3 refractor + CCD (Nerpio MPC Code - I89) confirms that this object is a comet: diffuse coma 1 arcminute and 30 arcseconds in diameter, with a sharp central condensation

New Comet: C/2012 C1 (McNAUGHT)

Cbet nr.3016, issued on 2012, February 11, announces the discovery of a new comet (discovery magnitude 18.8) by R. H. McNaught on CCD images obtained on February 5.5, 2012 taken with the 0.5-m Uppsala Schmidt telescope at Siding Spring. The new comet has been designated C/2012 C1 (McNAUGHT).

We performed some follow-up measurements of this object, while it was still on the neocp. Stacking of eight R-filtered exposures, 30-sec each, obtained remotely, from the Siding Spring-Faulkes Telescope South on 2012, Feb. 6.4, through a 2.0-m f/10.0 Ritchey-Chretien + CCD, shows that this object is a comet: coma about 5" in diameter, with a weak central condensation. The coma is slightly elongated toward the southwest.

Another New Comet: C/2012 B3 (LA SAGRA)

Cbet nr. 3012, issued on 2012, February 04, announces the discovery of a new comet (discovery magnitude 18.3) on CCD images taken with the 0.45-m f/2.8 reflector at La Sagra, Spain on January 29.1, 2012. The apparently asteroidal object was later noted by Jaime Nomen on La Sagra images taken on Jan. 30.2 to be a possible comet with slight diffuseness. The new comet has been designated C/2012 B3 (LA SAGRA).

We performed some follow-up measurements of this object, while it was still on the neocp. Stacking of 10 R-filtered exposures, 20-sec each, obtained remotely, from the Haleakala-Faulkes Telescope North on 2012, Jan.30.6, through a 2.0-m f/10.0 Ritchey-Chretien + CCD, under good seeing conditions, shows that this object appears "soft", compared to the nearby field stars of similar brightness (stellar FWHM of 1.2").

Comet Lovejoy as seen from Australian outback

This is the out-of-this world photograph of the beauty of an amazing comet streaking across the cosmos.

Caught on camera over a swamp in Australia the stunning image shows the trail of the Comet Lovejoy as it passed close to Earth.

Lying in wait in the darkness in Poocher Swamp Game Reserve near Adelaide, was photographer Wayne England who took this amazing snap.

As his picture shows the darkness of the swamp and the reflection of the water made the perfect backdrop to reflect the comet zooming across the sky.

Mr England, 40, who is a member of the Astronomical Society of South Australia, said he first heard about the comet travelling close to Earth in December and had several nights to try and catch a glimpse at 4am in the morning on Christmas Eve.
