Did I see a mentionable event in Germany early morning on 6th of February 2019? Around 6.15am (GMT + 1) on the 6th of February 2019 I 
was looking out of my window somewhat north, when I saw something one would probably call a shooting star. The features were:


A magnitude I haven't seen before; it even had a soft blinding effect, that's how bright it was.
From my view frame it moved from my right to my left (so most likely from east to west). 
The size was a quarter to half of what the moon usually has from my view frame.
It traveled almost through the sky half I was able to see within half a second before its glow was immediately gone again. 


I am assuming the object must have been either very large and fast or quite close.

Was there any meteor worthy mentioning passing by Earth at that given time?
Or are the features I just described way more common than I am assuming, and I just spotted an event that happens quite regularly?
Fireballs are real but rare events. Meteors are formed when small rocks enter the atomsphere from space. Larger rocks or small asteroids will produce brighter meteors. The brightest meteors are called fireballs or bolides. It is not uncommon for parts of the rock that made the fireball to survive and can later be found as meteorites.
A couple of things can be confused with fireballs.  When satellites re-enter, they can burn up. Satellites move much more slowly than true fireballs, most fireballs last less than 10 seconds.
A comet is an astronomical, not atmospheric, object. It looks like a fuzzy star with a tail. It remains almost motionless in the sky, sometimes for months. Really bright comets are rare, and even the brightest comets are much much dimmer than a fireball.
There are several organisations that collect reports of fireballs:

The advice given states:


Please, don't report sighting that lasted more than 30 seconds: the vast majority of fireballs are only visible for few seconds.
Please, don't report recurring events: seeing a fireball is extremely rare and often a once in a lifetime event.
Please, don't report slow blinking objects or lights crossing the sky going by 2 or 3: a fireball looks like a big shooting star.
