Radiant of meteors
|Some parameters have to match with such photo actions. A clear night sky, new moon and the Perseids almost give this meteor cocktail shown below by showing a radiant. This means that all the meteors appear to come from one point. This point is located in the constellation Perseus, from where the meteor shower is named.|
Nikon 10,5mm fisheye, f2.8 on Sony a7III, composit of 25x5 sec, ASA 6400
This photos were taken near Donauwörth. Significant is the green entrance color which is changing into red.
After an inquiry at the working group Meteore e.V. the following information from Mr. Roland Winkler was given.
The colored impression results in any case from reciprocal effect of meteorite material with the upper atmosphere layers. Deceleration speed and temperature plays a rather subordinated role. A member of our association (working group Meteore e.V.) had put on a statistics over some years ago in order to the meteor colors, which brought however no reference to your statement above ( snief!! ). Usually Meteors are visually observed usually from the white color, perhaps with a weak bluish inside. With the appearance of bolides sometimes different colors can be observed.
