Bright fireball over Belgium and Netherlands
A bright fireball streaked across the night sky over Belgium and Netherlands at around 20:12 UTC on February 15, 2019. The event lasted several seconds.

The International Meteor Organization (IMO) received 107 eyewitness reports. The object was mostly seen from the Netherlands, northeastern Belgium and western Germany but people from southeastern England and as far south as Paris and Beaune, France also witnessed the event.

Another fireball was seen over northeastern Germany at 22:00 UTC on February 17 and was reported by 62 people so far. There are no images or videos of this event at this time.

'Enorme vuurbal' boven Gelderland blijkt meteoor
APELDOORN - Door het hele land was vrijdagavond een vallende ster te zien. Op sociale media werden meerdere meldingen van de vuurbal gedaan, onder meer vanuit Apeldoorn, Ede en Nunspeet.

Rond 21.10 uur werd het eerste filmpje geplaatst op Twitter waarop de vallende ster te zien is. Daarna stroomden de meldingen vanuit het hele land binnen. Sommigen spreken van een grote, groene vuurbal die door de lucht schoot, anderen juist van een blauwe flits.

Volgens MeteoGroup is het bijzonder dat de vallende ster zo duidelijk te zien was: 'Het was een kraakheldere nacht, dus daarom was de meteoor zo zichtbaar.'

Dat dit natuurverschijnsel door heel Nederland en zelfs in BelgiŰ en Engeland te zien was, komt doordat zo'n flits op grote hoogte door de lucht raast en ook nog eens ontzettend groot is.

Grote vuurbal gezien boven Vlaanderen en Nederland

Tientallen mensen zagen gisteren een prachtig schouwspel boven delen van Nederland en Vlaanderen: een meteoor. De enorme vuurbal flitste iets na negen door de hemel. Een vallende ster is niet ongewoon, maar het levert wel spectaculaire beelden op.

De Nederlandse verslaggever Martin Drent van RTV Noord zag een “hele heldere, blauwe lichtkogel die naar beneden viel” en dacht eerst dat het vuurwerk was. Weerman Frank Deboosere kwam snel met een logische verklaring voor het verschijnsel: het is een gewone vallende ster of meteoor.

Brilliant Green Fireball Lights Up Florida Sky

A bright green fireball east of Tallahassee, Florida sparked nearly 250 witness reports for the American Meteor Society across several states.

The large flash occurred on Saturday (March 30) at 11:52 p.m. local time, according to the society's event sighting page. It was visible in Florida, Georgia, Alabama and South Carolina, and possibly sighted as far north as Virginia.

Some witnesses reported the fireball being visible for 20 seconds, although the majority saw it as a briefer flash of just 3.5 seconds, according to the sightings page. "The glow from the burning meteor was so bright that it created shadows for several seconds before the light flickered out,

Fireball Asteroid Hit Earth Last Weekend, Impact Equal To 5,000 Tons Of TNT

Last weekend, Earth was hit by an asteroid that produced an energy equivalent to 5,000 tons of TNT. Before exploding, astronomers were able to spot the asteroid using telescopes.

According to astronomer Peter Brown, the minor impact event happened on June 22 after a small asteroid exploded in the sky toward south of Puerto Rico. The explosion happened at around 5:30 pm EDT and produced an energy of around 5,000 tons of TNT.

Despite the high amount of energy released by the asteroid, no one was reportedly injured because of the event. This is primarily due to the object burning up and detonating shortly after entering Earth’s atmosphere. Reports indicated that the asteroid was only about 10 feet long.

Ernesto Guido, an astronomer from Italy, noted that the asteroid’s name is 2019 MO or NEOCP A10eoM1. He shared a satellite image captured by NASA and the National Oceanic and Atmospheric Administration of the asteroid as it entered the planet’s atmosphere.

The fact that asteroid 2019 MO was detected by astronomers and space agencies before hitting Earth came as a surprise as it was such a rare event. Although NASA noted that Earth gets frequently hit by small asteroids and meteors every year, spotting them before they enter the atmosphere is a bit uncommon.

In fact, 2019 MO’s recent visit marked only the fourth time an asteroid was detected before it hit Earth, according to CNET. The other instances occurred during the last 12 years. One of them was the small asteroid that exploded over Africa in 2018. This asteroid came so close to the surface that scientists were still able to find small fragments of it on the ground.

Although being able to detect asteroids before hitting Earth is becoming more common within the last couple of years, this does not automatically mean that impact events are becoming more frequent.

Instead, this simply means that the equipment agencies and amateur astronomers use are becoming more sophisticated and accurate when it comes to spotting incoming space rocks. NASA even has a specific department dedicated to monitoring asteroids as they approach Earth’s vicinity.

Zet in je agenda: 14 september vliegt een joekel van een astero´de langs

Op 14 september scheert Asteroid 2000 QW7 langs onze aarde. De astero´de heeft een diameter van zeker 300 meter; dat zijn zo'n drie Groningse Martinitorens op elkaar. Qua hoogte is 2000 QW7 met 650 meter helemaal imponerend.

Het gigantische stuk ruimtesteen vliegt met ruim 23.000 kilometer per uur op 5,3 miljoen kilometer voorbij. Ter vergelijking: de maan staat op zo'n 380.000 kilometer en Mars gemiddeld op 225 miljoen kilometer.

Zekere voor het onzekere
Asteroid 2000 QW7 komt dus bÚst dichtbij. Zeer waarschijnlijk vormt het geen gevaar voor onze planeet, maar NASA neemt het zekere voor het onzekere en houdt de baan van de astero´de nauwlettend in de gaten.

De astero´de komt vaker langs: zo eens in de 19 jaar. Volgens The Weather Channel is de volgende passage op 19 oktober 2038.

Objecten als 2000 QW7 zijn zelden te zien vanaf de aarde. Astero´de 99942 Apophis is van een vergelijkbare grootte en komt 13 april 13 2029 31.000 kilometer langs. Apophis is dan in gebieden zonder al te veel lichtvervuiling waarschijnlijk wel zichtbaar.

Extremely close flyby (0,03 LD!!) of asteroid

A newly discovered asteroid designated 2019 UN13 flew past Earth at an extremely close distance of just 0.03 LD / 8.43e-5 AU (12 611 km / 7 836 miles) at 14:45 UTC on October 31, 2019.

The asteroid was discovered early October 31 at Catalina Sky Survey, Arizona, just several hours before its close approach.

The object belongs to the Aten group of asteroids and has an estimated diameter between 1 and 2.2 m (3 - 7.2 feet).

It flew past us over Africa at a speed of 12.85 km/s. Its trajectory was heavily influenced by Earth's gravity, sending its aphelion out to the asteroid belt between Jupiter and Mars.

Its flyby marks the third closest approach of any known asteroid on record, including 2010 RF12 expected to flyby us in September 2095, and the second closest since 2011 CQ11 on February 4, 2011.

This is the 61st known asteroid to flyby Earth within 1 lunar distance since the start of the year, including 2019 VA expected on November 2, and 11th in the month of October.
