Good morning RP. Staying with a spring-time theme, today's image is titled "Star Trails and the Equinox Sunrise." Note how stars curve around the northern celestial pole to the left, and southern celestial pole to the right. The celestial equator is the diagonal straight line in the center of the image. The camera is facing west; sunrise (east is) behind the viewer.

Thank you, my friend Maj William W. 'Bill' Price for sharing the daily NASA photo for march 21, 2019 "Star Trails and the Equinox Sunrise."

Explanation: Stars trail and the Sun rises in this night and day composite panorama made on March 19. The view looks toward the eastern horizon from La Nava de Santiago, Spain. To create it, a continuous series of digital frames was recorded for about two hours and combined to trace the concentric motion of the stars through the night sky. A reflection of the Earth's rotation, star trails curve around the north celestial pole toward upper left and the south celestial pole toward the lower right. Of course on that day the Sun was near the celestial equator, a diagonal straight line in the wide-angle projection. A dense dimming filter was used to capture the Sun's image every two minutes. Superimposed on the star trails it rose due east in the morning sky. In the scene, foreground landscape and a local prehistoric monument were illuminated by full moonlight, though. The monument's corridor faces nearly to the east and the equinox sunrise."
Thank you, my friend Maj Marty Hogan for mentioning me.
