Deranged Dating: Cometary Carbon-14

Earth Scientists apparently accept radiocarbon dating as the gospel truth.

However, if the Settled Science that supports radiocarbon dating is really just one huge homogenised hodgepodge then acquiescent Earth Scientists are simply being misdirected and left to flounder in the dark.
This would go some way towards explaining why so many Earth Scientists are gainfully employed chasing their tails.

Thus, the mainstream gained the scientific kudos associated with Radiocarbon Dating whilst [simultaneously] wrestling control of the Settled Science away from Willard Libby by imposing a calibration curve that was approved by the mainstream.

Sadly, this hybrid, high jacked and half-baked Settled Science has now degenerated into a recursive [incestuous] feedback loop where dendrochronology calibrates Radiocarbon Dating which, in its turn, is used to calibrate dendrochronology.

Amongst the many issues associated with the Settled Science of radiocarbon dating there is the curious case of Catastrophic Cometary Carbon-14.

Arguably, the burning up of a cometary debris train in the Earth's atmosphere would significantly enhance the level of atmospheric Carbon-14.

Comet 2

Another comet brightens and now visible in the Northern hemisphere


Terry Lovejoy's new comet has gone from faint to bright in just three weeks and is now a tempting binocular target at dawn.

Comet C/2017 E4 Lovejoy was discovered on March 9th by Australian amateur Terry Lovejoy. It's his 6th discovery and seen here on March 25th.
Who doesn't love a comet that exceeds expectations? That's exactly what's happening with Terry Lovejoy's latest discovery, C/2017 E4 Lovejoy.

Discovered on March 10th at magnitude +12, early observations suggested a peak magnitude of +9 in mid-April, assuming it didn't crumble apart en route to an April 23rd perihelion.

Forget that. This fuzzball's already at magnitude +7 - 7.5 and a snap to see in 50-mm binoculars.

I know because I got up Wednesday morning (March 29th) shortly before the start of dawn, pointed my 10×50 glass just below the figure of Equuleus, the Little Horse, and saw a small, dense ball of glowing fuzz without even trying.

Comet 41P/Tuttle-Giacobini-Kresak — now circumpolar in Ursa Major — shines at a similar brightness, but it's larger and less condensed and therefore not as easy to see as Lovejoy.

Comet Lovejoy captured with a 135-mm telephoto lens (f/2.8, ISO 2500, 10-second exposure) on Wednesday morning March 29th, when it entered the small constellation Equuleus. Though small at this focal length, the comet's blue-green color is a dead giveaway.
A little more than a week ago, Comet Lovejoy glowed at magnitude +10 - 11; a few days ago it was at +9. Given its meteoric rise in brightness, observers are anticipating the comet to crest to magnitude +6 around perihelion as it describes a roller coaster arc across Pegasus and Andromeda. Twice it passes bright deep-sky objects: the bright globular cluster M15 on April 1st and the Andromeda Galaxy on April 20 - 22. Another easy time to spot it will be on April 8 - 9 alongside β Pegasi in the northwest corner of the Great Square.

Green comet flyby on April 1st

Green comet 41P/Tuttle-Giacobini-Kresak is flying over Earth's North Pole this week where sky watchers can find it all night long not far from the bowl of the Big Dipper. At closest approach on April 1st it will be just 21 million km from Earth--an easy target for backyard telescopes and almost visible to the naked eye. Amateur astronomer Yasushi Aoshima sends this picture of the approaching comet from Fukushima, Japan:

"On March 22nd I caught 41P 'eating' M108, the Surfboard Galaxy," says Aoshima. "The comet's green atmosphere appeared to swallow the distant spiral galaxy as it exited Ursa Major."

Eyewitnesses wanted: did you see bright green meteor fireball in Irkutsk, Siberia?

Scientists in the Russian city of Irkutsk (Siberia) are searching for people who could have witnessed the fall of a celestial body glowing bright green, Executive Director of the Irkutsk Planetarium Pavel Nikoforov told TASS.

"At 14:39 local time (11:39 GMT), while we were riding in a car along the bridge across the Irkut River towards the Leninsky district, we spotted an unusual glowing object in the daytime sky. It was speeding at a 45 degree angle, but its light went out in just a couple of seconds. We very much hope that Irkutsk's residents may have recorded this phenomenon using their car DVRs. We could collect these recordings and hand them over to scientists," he stated.

The fact that the celestial body was seen in the daytime, speaks volumes for its enormous weight, a source in the Astronomical Observatory of Irkutsk State University told TASS. "We assume that a celestial body weighing several kilograms could be glowing so brightly in the daytime. If we are provided with video recordings showing the bolide, then we could calculate its weight and trajectory," the source added.

In the autumn of 2016, residents of the Irkutsk region and the Republic of Buryatia witnessed a bright green meteor soaring above Lake Baikal. It was later dubbed the Baikal Bolide. Scientists believe that its weight was about 80 kilograms but because of its high speed it burnt up in the atmosphere.

Lunar impact event sighted

X marks the spot where the meteorite hit the moon.
Space scientists at Aberystwyth University have reported what they believe to be the first confirmed sighting in the British Isles of a meteorite hitting the Moon.

A Lunar Impact Flash - a flash of light when something hits the Moon's surface - was recorded on the southern hemisphere of the Moon and probably caused by a small meteorite the size of a golf ball.

Lasting less that one tenth of a second, the image was caught on New Year's Day 2017 on a remotely operated telescope at Aberystwyth University.
Lunar Impact Flashes are notoriously difficult to record. The meteorite would be travelling at anywhere between 10 to 70 km per second as it hit the surface of the Moon. That is the equivalent of travelling from Aberystwyth to Cardiff in just a few seconds, and the resulting impact would be over in a fraction of a second.

A similar meteorite hitting the Earth's atmosphere would produce a beautiful shooting star, but as the Moon has no atmosphere it slams into the surface, causing a crater the size of very large pot hole. Just under 1% of the meteorite's energy is converted into a flash of light, which we were able to record here in Aberystwyth.

- Dr Tony Cook, Aberystwyth University
Scientists estimate the Moon is hit by similar sized meteorites as often as once every 10 to 20 hours.

Comet Halley - Close encounters of the cometary kind

Researchers trawling through the dusty corners of the Academic Archives primarily have to rely upon serendipity to provide them with break-through information.

However, when serendipity strikes the results can be startling.

Such was the case a few weeks ago when the Glen Turret Fan chronology neatly slid into place between the Arabian Horizon and the Heinsohn Horizon in the Old Japanese Cedar Tree chronology.
The Glen Turret Fan in upper Glen Roy contains 276 annual sedimentary layers that are coincidentally close to the 277 years between the Arabian Horizon of 637 CE and the Heinsohn Horizon of 914 CE i.e. the Heinsohn Sandwich.
...
The unexplained arrival of the Sand Bed in the Glen Turret Fan [upper Glen Roy] in 759 CE coincidentally echoes:

a) the unexplained Smothering of Samarra in sand
b) the unexplained Covering of Cologne in sand
c) the unexplained Clear Black Horizons in sand across Southern England and Scotland
d) the unexplained Sandy Sludge Layers in the Greenland Ice Cores...

And then serendipity struck again in form of Comet Halley.

Comet Halley has several remarkable aspects.

New Comet: C/2017 E4 (LOVEJOY)

CBET nr. 4373, issued on 2017, March 13, announces the discovery of a comet (magnitude ~15) by Terry James Lovejoy on three CCD 8-s exposures taken five minutes apart starting on Mar. 9.684 UT with a Celestron C14 reflector operating at f/1.9 (+ QHY9 camera). The new comet has been designated C/2017 E4 (LOVEJOY).

I performed follow-up measurements of this object, while it was still on the neocp. Stacking of 10 unfiltered exposures, 30 seconds each, obtained remotely on 2017, March 10.7 from Q62 (iTelescope network) through a 0.50-m f/6.8 astrograph + CCD + focal reducer, shows that this object is a comet with a diffuse coma nearly 15 arcsec in diameter.

New Comet: C/2017 E1 (Borisov)

CBET nr. 4369, issued on 2017, March 04, announces the discovery of a comet (magnitude ~17) by Gennadii Vladimirovich Borisov on three unfiltered 120-s exposures obtained on Mar. 1.10 UT with a 0.4-m f/2.3 astrograph at the "Mobil Astronomical Robotics Genon" Observatory (MARGO) near Nauchnij. The new comet has been designated C/2017 E1 (Borisov).

I performed follow-up measurements of this object, while it was still on the neocp. Stacking of 20 unfiltered exposures, 30 seconds each, obtained remotely on 2017, March 1.5 from H06 (iTelescope network) through a 0.43-m f/6.8 reflector + CCD + f/4.5 focal reducer, shows that this object is a comet with a diffuse coma nearly 30 arcsec in diameter.

Loud boom and reports of fireball sighting over Texas

Meteor over Abilene
© KTXS 12 ABC
Abilene - Many people reported to KTXS that they saw a fireball moving across the sky Sunday evening just before 9 p.m. Most of the reports came from an area from Abilene to Snyder.

People in the Snyder region also reported hearing a boom like that of a transformer failing or a sonic boom that a jet might create.

Based on the reports, it appears that something fell from the sky and got close enough to the ground that the sonic boom it created was audible to people on the ground in parts of our area. However, we have not received any reports of anything crashing to the ground.

The object could have been man-made space debris like a piece from a spent rocket. But we have not heard of any of these reentries from NASA or our military. More likely it was a piece of "rock" wandering around in our solar system that fell into our atmosphere.

As the object falls deeper into our atmosphere friction with air molecules increases and heats the object. This creates the streak of light in the sky. Most of the time the falling object burns up before hitting the ground.Since the falling object is likely traveling at several thousand miles per hour, it creates a sonic boom. If it is close enough to the ground, we may hear it.

Checking for a possible noise maker, the USGS earthquake site indicates no measured earthquakes in the state of Texas Sunday or Sunday evening.


Comment: Footage of the meteor was also captured by a police officer in Weatherford, Texas.

Meteor fireball sighted over South Island, New Zealand

Clear skies around the country allowed for sightings of what may have been a meteor (not pictured) last night.
Reports of a bright light shooting across the skies last night have come in from around the country, including Dunedin.

ODT Online submitter Peter Simkins relates looking out of his window in Broad Bay towards Port Chalmers and seeing a ''yellow streak of light plummeting to earth''.

Other sightings have come in from in Blenheim, Porirua, Lake Ferry, Martinborough and New Plymouth.

Some people posted on social media about seeing the sky light up, while others described the light as being green in colour. Fairfax is this morning reporting that it may have been may be a Russian cargo rocket re-entering the earth's atmosphere.

One woman posted on Facebook that she saw the light in Lower Hutt.

"Yup saw it clearly in Lower Hutt. It was huge and the tail colorful."

The Herald was unable to contact an expert to comment on the sighting tonight, but a person at the University of Canterbury's Mt John Observatory said descriptions provided indicated people had seen a meteor.

According to Nasa, small chunks of rock and debris in space are called meteoroids.

They become meteors, or shooting stars, when they fall through a planet's atmosphere; leaving a bright trail as they are heated to incandescence by the friction of the atmosphere. Pieces that survive the journey and hit the ground are called meteorites.
