SOTT Focus: SOTT Earth Changes Summary - February 2017: Extreme Weather, Planetary Upheaval, Meteor Fireballs

Fireball Illinois
Februrary 2017 continued on as January started. Massive flooding in California due to "atmospheric rivers" dumping large amounts of rain on coastal areas and snow on the Sierra Nevada. The snow melt from this caused further flooding in Nevada. Eastern Canada also experienced record snowfall, as did Iran, Kazakhstan, Afghanistan and Japan.

Wildfires broke out in Eastern Australia and New Zealand while record rainfall inundated Western Australia. Major flooding also hit several South American nations including Chile, Peru and Colombia.

There are at least 30 active volcanoes around the world right now, including a really impressive one in Guatemala. Massive earth cracks opened in Pakistan and Italy.

These are just some of the chaotic events we present in this month's Sott 'Earth Changes' video compilation.


Comet 2

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

© Photo Twitter (@iangriffin)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.

Asteroid 2017 DG16 to fly by Earth at 0.34 LD - 5th known NEA to flyby Earth within 1 lunar distance since January 8, 2017

The Moon's orbit is grey. The blue arrow points in the direction of Earth's motion and the yellow arrow points toward the Sun.
A newly discovered asteroid named 2017 DG16 will flyby Earth at a very close distance of 0.34 LD (130 560 km / 81 126 miles) from the surface of our planet at 21:08 UTC on February 23, 2017. This is the fifth known near-Earth asteroid to flyby Earth within 1 lunar distance since January 8, 2017.

2017 DG16 was first observed by Mt. Lemmon Survey on February 21. The estimated size of this asteroid is between 2 and 8 m (6.5 - 26.2 feet). It will flyby Earth at a speed (relative to the Earth) of 6.91 km/s.

This object belongs to the Apollo group of asteroids, Earth-crossing asteroids that have an orbital semi-major axis greater than that of the Earth (> 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU).

Three meteor fireballs reported over Cheltenham, UK in two days

Did you see two fireballs in the sky above Cheltenham on Sunday evening?

We have been contacted by someone who said they saw the phenomenon as they drove along Princess Elizabeth Way.

He asked us via twitter: "Seen two fireballs in the sky when heading down Princess Elizabeth Way. Heard anything?" He added that he was driving with his son and noticed two bright lights which dimmed and left smoke trails. I really can't believe me and my son would have been the only ones to see them, they were bright enough," he said.

East London gallery under fire for hosting 'neo-Nazi' art & 'Islamophobic' speakers

A London art gallery has been criticized for exhibiting neo-Nazi artwork, hosting openly Islamophobic speakers and "promoting fascism."

LD50, in Dalston, east London, is facing calls to shut down over an exhibition and a series of talks hosted by the far right or so-called 'alt-right' movement, which is known for its vehement anti-liberal stance, often favoring white supremacist views.

Last summer, the gallery, run by Lucia Diego, held a 'neoreaction conference' featuring speakers including Peter Brimelow, Brett Stevens and Iben Thranholm. 'Neoreaction' is a 'philosophy' which rejects democracy, is anti-egalitarian and embraces autocratic rule.

Bright meteor fireball seen over northern U.S and Canada

Fireball over Pennsylvania
A very bright fireball was seen in the northern US and Canada around 04:53 UTC on February 18, 2017. The event was captured in 3 NASA all-sky cameras and cameras belonging to the Southern Ontario Meteor Network.

Analysis of the video data shows that the meteor was first detectable at an altitude of 83 km (52 miles) above US Highway 219, southeast of the Pennsylvania town of DuBois. It then moved northeast some 42 km (26 miles) through the atmosphere at almost exactly 64 400 km/h (40 000 mph), ablating 42 km above the countryside just north of Winslow Hill, NASA's Meteoroid Environment Office (MEO) said.

The camera data shows very little deceleration of the meteor, which gives it a poor chance of producing meteorites, MEO said and added that more analysis is required to rule this out. "The object had the brightness of a quarter Moon, which means we are dealing with an asteroid fragment weighing about 9 kg (20 pounds), with a diameter of roughly 18 cm (7 inches)."
