PALM BAY, Fla. - A mysterious, fiery object falling from the sky was reported in Brevard County, prompting authorities to launch a search, officials said.
Nothing was found after 911 callers reported seeing a fiery object falling to the ground.
The calls were received about 7 a.m. Thursday, with reports of the mysterious object striking the area near the Interstate 95 onramp on the southbound side of Palm Bay Road.

The annual Geminid meteor shower peaks tonight, Dec. 13-14, as Earth passes through a stream of gravelly debris from "rock comet" 3200 Phaethon


by Dr. Tony Phillips.

GEMINID METEOR SHOWER--TONIGHT!


The annual Geminid meteor shower peaks tonight, Dec. 13-14, as Earth passes through a stream of gravelly debris from "rock comet" 3200 Phaethon. Dark-sky observers in both hemispheres could see as many as 120 meteors per hour during the dark hours between midnight and sunrise on Dec. 14th. Last night, Dec. 12-13, NASA's all-sky meteor network detected 15 Geminid fireballs over the USA. That number will surely grow on peak night--tonight! Got clouds? Listen for Geminid echoes in the audio feed from our live meteor radar.

Geminids meteor shower prediction: Moonless and marvelous
 
 
  • Geminids meteor shower is peaking
  • Geminid meteors can flash into view anywhere in the night sky

(Sky and Telescope)The nights of December 13-14 offer dark skies for a popular, underappreciated meteor display.

The Geminid meteor shower competes with August's Perseids for showiness — yet it's not nearly as well-known. The Geminids are easier on your sleep schedule, too. Their radiant (near Castor in Gemini) climbs as high by 11 p.m. standard time (45 degrees above the local horizon) as the Perseid radiant does by 2 a.m. daylight time on the peak Perseid nights. The higher the radiant, the more meteors you'll see.

The Geminid meteors can flash into view anywhere in the late-night sky when the shower peaks in mid-December. But if you follow their paths back far enough, they all appear to diverge from a point in the constellation Gemini.
The International Meteor Organization (IMO) predicts that the Geminids should reach an impressive zenithal hourly rate of 120 this year. (ZHR is how many meteors you'd see see per hour in a very dark sky if the radiant were at the zenith. This year the peak should be centered on roughly 18h Universal Time on December 14. Unfortunately, that's 1 p.m. EST and 10 a.m. PST. So in North America the shower's performance is likely to be similar on the nights of December 13-14 and 14-15.
 
As the IMO notes, "Near-peak Geminid rates persist for almost a day, so much of the world has a chance to enjoy something of the shower's best." In addition, "mass-sorting within the stream means fainter telescopic meteors should be most abundant almost a day ahead of the visual maximum," and the meteors after maximum are typically brighter than average.

The moon will be a waxing crescent a few days old, no trouble at all.

Tina Robertson was just trying to catch a stray cat out in front of her property when she heard it.
“It freaked me right out,” she said.

Then she looked up to see a “big ball of fire.”

“It was moving like hell,” she said. “It was big, but not as big as that one in Russia.”

What she and other witnesses as far afield as Seattle and Nanaimo seem to have seen around 6:50 p.m. Friday was a type of meteor known as a bolide. Bolides are as bright as a full moon; they’re a meteor that doesn’t just burn up as it travels through the atmosphere, it explodes.

(Hat tip to Seattle Twitter user Reb Roush for pointing us all to the term.)

Robertson’s partner Wilf Krickhan was loading up firewood in a bobcat behind the house when he saw the blue-green bolide flash across the sky.

All Sky Fireball Network

 

by Dr. Tony Phillips.


Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics. Daily results are presented here on Spaceweather.com.
On Nov. 17, 2015, the network reported 38 fireballs.
(23 sporadics, 9 Northern Taurids, 3 Leonids, 2 November I Draconids, 1 omicron Eridanid)

Near Earth Asteroids


Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
On November 18, 2015 there were 1634 potentially hazardous asteroids.

An aurora-hunting north-east photographer has captured a stunning image of a meteorite fireball falling to earth.




PICTURES: The perfect moment in space and time caught above Aberdeenshire

9 November 2015 by Andrew Douglas

Wow
Wow



An aurora-hunting north-east photographer has captured a stunning image of a meteorite fireball falling to earth.

Leigh-Ann Mitchell, from Ellon, had been out at the weekend scouring the night skies for any sign of the Northern Lights.

The self-proclaimed “aurora chaser” settled at Pitfour Estate in Mintlaw, where she thought she had the best chance of capturing the spectacular light show.

But the 40-year-old amateur snapper got more than she bargained for when she captured the moment a fireball from the Taurid meteor shower fell from the sky, combined with the heavenly aurora glow.
The shower is notorious for producing fireball flares, and experts said this year would be the best chance to witness them yet.

Mrs Mitchell’s photograph has been viewed thousands of times since it was taken in the very early hours of Saturday morning, and shared across social media in every corner of the globe.

Incredible green meteor pictured off coast of Yorkshire
Looks pretty creepy, but is pretty logical (Picture: Ross Parry)
It might look like something from Close Encounters of the Third Kind – but there’s an entirely logical reason for this eerie green light hovering in the sky above a home.

It’s actually a meteorite – and was captured on camera by Peter Horbury as it flashed through the clear night sky near Whitby, North Yorkshire.

The remarkable sight was captured at the same time as the Taurid Meteor Shower passes Earth – with larger cellestial debris being more visible than usual.

Peter, 57, captured the snap at 1.30 am on Saturday after he headed to Hornblower Lodge in Whitby, North Yorkshire.

Fireballs are falling to Earth tonight in numbers we won't see for another 10 years



 

here's how to watch


jorwig@businesssinsider.com (Jessica Orwig) 


Keep your eyes peeled tonight for some spectacular fireballs lighting up the sky.

Fireballs are extremely bright meteors, and right now Earth is in the midst of the Tuarid meteor shower, which is peaking on the night of Wednesday, Nov. 11.
"The best time to view the Taurids is from midnight to 3 am local time," NASA wrote in a Reddit AMA. "There should be a handful per hour. Taurid rates are not high, but the ones you will see will be very bright."

The peak of the shower — when we can see the most meteors per hour — is expected to have between seven to 10 meteors per hour, and some of those are almost certain to be a fireball. The best way to watch any meteor shower is to get far away from city lights and look up, no special equipment required.

However, fireballs are bright enough to be seen even amidst city lights, so if you can't get far away from the city, there's still a chance you might spot one, or more.

Look to Taurus

Meteor showers usually happen when Earth passes through a comet's stream of residual dust and debris in space.

 The debris collides with our planet, is pulled toward Earth's center by gravity, and burns up in the atmosphere, producing bright streaks in the night sky that we sometimes refer to as falling stars.
Compared to other meteor showers, the Taurid meteors are relatively sluggish, colliding with Earth at speeds of about 65,000 mph — less than half the speed of the rapid Perseid meteors, which move at about 133,000 mph.
