Comet in the Sky!

Earlier this year, the NEOWISE space telescope discovered its latest comet, a distant and inconspicuous object.
At the time of its discovery on March 27, the comet — dubbed Comet NEOWISE (short for Near Earth Object Wide-field Infrared Survey Explorer) and cataloged as C/2020 F3, was located 194 million miles (312 million kilometers) from the sun and shining at a very faint magnitude of +17 — that’s about 25,000 times fainter than the faintest star that can be glimpsed with the naked eye. It was only visible with large telescopes.
NEOWISE is about to take center stage, which we visualize in two diagrams; one for the morning sky and the other for the evening sky. The time frames are for the beginning (morning) and end (evening) of nautical twilight, when the sun is positioned 12 degrees below the horizon, corresponding to approximately 80 minutes before sunrise and 80 minutes after sunset for those living at mid-northern latitudes. The lines extend directly away from the sun, showing the probable direction in the sky of the comet’s tail should one develop.

Me love science

The shades of blue move through the zones of twilight.
And twilight times are shown in the page below for the city you keyboard in. I am using Dallas, Texas :
