A bright object in the heavens above the North Okanagan got the attention of many people over night.

Social media has lit up with speculation as to what the object was.

Some jokingly speculated it was an alien invasion, but the most common theory - and the most likely - is it was a meteor.

"Just something very large fell towards Vernon...bright light maybe really large meteor? Started high in the east sky and rapidly lowered behind the hills in the west," Liana Battye told Castanet.

Posted one witness on Facebook, "It lasted maybe three-and-a-half seconds. It looked huge. Over by the Swan Lake area, we saw it from Middleton."

The light was so bright it was seen in Enderby and Kamloops.

Comment: The American Meteor Society (AMS) received 834 reports about a fireball seen over WA, OR, British Columbia, ID, Washington and Oregon on Sunday, July 30th 2017 around 04:53 UT.

The meteor was captured and posted on Twitter by Parker Sayers.

This amazing fireball was recorded on the night of 28 July 2017 at 3:29 local time ( 1:29 universal time). It was associated with the alpha-Capricornid meteor shower. The event was produced by a fragment from comet 169P / NEAT that impacted the atmosphere at about 90,000 km / h.

The fireball began at a height of about 104 km and ended at an altitude of around 75 km. It was recorded in the framework of the SMART Project from the astronomical observatories of Calar Alto (Almeria, Spain), La Hita (Toledo, Spain), Seville and Huelva.

This spectacular fireball flew over southern Cordoba in the early hours of July 28, at 3:29 local time (1:29 universal time). It occurred as a result of the entry into the Earth's atmosphere of a fragment from comet 169P / NEAT at about 90 thousand kilometers per hour. The luminous phenomenon began at an altitude of about 104 km and advanced in a northeasterly direction, extinguishing to about 75 km of altitude when it was almost on the vertical of the locality of Baena.


Comment: This is the third fireball recorded over Spain in the past 11 days:

This stunning fireball overflew Toledo and Madrid on July 27 at 00:35 local time (22:35 Universal Time on July 26). The event was produced by a rock from an asteroid that hit the atmosphere at around 54.000 km/h.

The fireball began at a height of about 80 km and ended at an altitude of 45 km. It was recorded in the framework of the SMART Project from the astronomical observatories of Calar Alto (Almería, Spain) and La Hita (Toledo, Spain).

This ball of fire flew over Andalusia on July 17 at 6:07 local time (4:07 UT). The event was caused by the entry into the Earth's atmosphere of a meteoroid of cometary origin.

The luminous phenomenon began on the province of Jaén, at a height of about 120 km above sea level, and ended at an altitude of about 75 km.

This beautiful fireball overflew the Mediterranean Sea on July 26 at 00:18 local time (22:18 Universal Time on July 25). The event was produced by a rock from an asteroid that hit the atmosphere at around 25.000 km/h. The fireball began at a height of about 83 km and ended at an altitude of 36 km. It was recorded in the framework of the SMART Project from the astronomical observatories of Calar Alto (Almería, Spain), La Sagra (Granada, Spain) and Sevilla (Spain).

A space rock now designated as asteroid 2017 OO1 was detected on July 23, 2017 from the ATLAS-MLO telescope at Mauna Loa, Hawaii. An analysis of its trajectory revealed it had been closest to Earth on July 20 sometime between 10:27 p.m. to 11:32 p.m. EDT (between 02:27 to 03:32 UTC on July 21).

This means the asteroid's closest approach occurred 2.5 to 3 days before it was seen. Asteroid 2017 OO1 flyby had passed at about one-third the Earth-moon distance, or about 76,448 miles (123,031 km).

Although that's still a safe distance, a fact that stands out is that asteroid 2017 OO1 is about three times as big as the house-sized asteroid that penetrated the skies over Chelyabinsk, Russia in February, 2013, breaking windows in six Russian cities and causing more that 1,000 people to seek treatment for injuries, mostly from flying glass.

Comet 2

New Comet: C/2017 O1

CBET nr. 4414, issued on 2017, July 24, announces the discovery of a comet (magnitude ~15.3) in the course of the "All-Sky Automated Survey for Supernovae" (ASASSN) program, from images taken with the 14-cm "Cassius" survey telescope at Cerro Tololo on July 19.32 UT. The new comet has been designated C/2017 O1.

I performed follow-up measurements of this object, while it was still on the neocp. Stacking of 10 unfiltered exposures, 60 seconds each, obtained remotely on 2017, July 23.7 from Q62 (iTelescope network) through 0.50-m f/6.8 astrograph + CCD + f/4.5 focal reducer, shows that this object is a comet with a sharp central condensation surrounded by diffuse coma about 3 arcmins in diameter.
