Wow! How lucky is that!?

This bright green bolide was captured on March 25th 2017 23:35 UT in rural Upper Austria. My camera was pointing in North-eastern direction and the brightest star in the picture - Vega - is located just above the bolide trail.

I was walking towards my exposing camera, when I suddenly saw this bright green light on my left that instantly made me turn my head. The meteor was very fast and it was so bright it even cast shadows on the ground. All that did not last longer than 1.5-2 seconds.

According to Pavel Spurny, head of the Department of Interplanetary Matter of the Astronomical Institute of the Czech Republic, this fireball occurred just South of the Lower Austrian town of Zwettl. It's trajecory was quite steep, the average slope was 77.8 degrees. Beginning height was 84.6 km and after a 57.3 km long luminous flight the bolide terminated at a height of 28.6 km. It’s initial mass was 5.7 kg and in the maximum it reached -11.1 absolute magnitude. It had a typical asteroidal orbit with perihelion near Earth orbit (0.9 AU) and aphelion in the central parts of the main belt of asteroids (2.7 AU). Within the European fireball network it received the number EN250317.

The photo was taken with a Nikon D610 and a AF-S 20mm f/1.8. Exposure time was 30 seconds at f/1.8 and ISO 800.
The location of where I took this picture can be provided - for scientific purposes only - upon request.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
