Meteorite above Russia

Today a meteorite exploded above Russia creating a chockwave resulting in huge material damage and injured hundreds of people. This meteorite is seen by many people and taped on video. See linkage below. Just to inform that the difference between a meteorite and a meteor : a meteorite finally touches ground, a meteor evaporates completely in our atmosphere (eg. meteor perseid showers in august)

Projection of the sun @ the sky

 
 
The graph was made based on the input from the website as mentioned earlier and calculated for the location at Averbode (Belgium) using Excel. Calculations done for the first day of the month from Jan till June. Using every time the first day results in the orbit of the sun not crossing the 90/270° in March. Of course this will happen at March 21st - Springtime.
Curious to see of the solargraph will show the same pattern.... :)

In order to compare the solargraph lines with sunshine hours I will use the sunshine hours from KMI.
