The phenomenon, known since 1988, requires some specific conditions for photographic recording.
Meanwhile, a very clear evening without haze.
The Moon around the first or last quarter, both to have the tail at 90° with respect to the sight potion, and to make visible the faint shadow due to the blocking of the resonance florescence. This draws a kind of darker streak in the exosphere.
Combining 8 guided images on the moon of 30 seconds at ISO 3200 and the use of two coupled low-Na-band filters with Helios 58mm lens, the shadow appears to have been registered despite the interference of the spikes.
A good discussion is in this recent paper:
