Disheveled Dusk Ghost
“The sun had left he sky, the birds now silent. In vague velvety half-light he appeared for a short while, and then was gone.”
At civil dusk, the centre of the Sun's disc goes 6° below the horizon in the evening. It marks the end of civil twilight, which begins at sunset. At this time objects are still distinguishable and, depending on weather conditions, some stars and planets may start to become visible to the naked eye. Beyond this point artificial light may be needed to read a book outdoors.
Clandestine release of shabby dusk ghosts becoming visible and available for a short time at that transitory period between day and night.
