Good morning, Rallypoint, and welcome to the January 14th edition of Astronomy Picture of the Day (APOD): "Perihelion 2023." You may recall that the Earth orbits the Sun in an elliptical orbit. That means there will be two points when the Earth is nearest (perihelion) and farthest (aphelion) from the Sun. We passed our solar perihelion on January 4th, and this photo was captured from the Barden Ridge Observatory (in Australia) a day later. Truly an image of the Fires of Creation.

Thank you my space-exploration advocate friend and brother-in-Christ Maj William W. 'Bill' Price for posting the Saturday, January 14, 2023 Astronomy Picture of the Day (APOD): Perihelion Sun 2023

APOD "Explanation: Perihelion for 2023, Earth's closest approach to the Sun, was on January 4 at 16:17 UTC. That was less than 24 hours after this sharp image of the Sun's disk was recorded with telescope and H-alpha filter from Sydney, Australia, planet Earth. An H-alpha filter transmits a characteristic red light from hydrogen atoms. In views of the Sun it emphasizes the Sun's chromosphere, a region just above the solar photosphere or normally visible solar surface. In this H-alpha image of the increasingly active Sun planet-sized sunspot regions are dominated by bright splotches called plages. Dark filaments of plasma snaking across the solar disk transition to bright prominences when seen above the solar limb. "
