What is HIP 101909

Hot blue in the small Delphinus, some 1,348 light-years away. Its light set off toward us when the Byzantine Empire was securing Constantinople and Greek manuscripts were being copied in its scriptoria. A blue flash leaping between the stellar waves of the dolphin, crossing thirteen centuries only to end as a minute spark above our heads.
