Moon and Antares in Reflected Volcanic Sunset.
The almost daily vivid volcanic sunsets in parts of the Southern Hemisphere due to stratospheric aerosols from the January Hunga-Tonga eruption are often being followed by the appearance of late reflections of colour (reflected dusking) along the whole of the opposite horizon. Three quarters of an hour after sunset on 13th June the almost Full Moon and Antares were photographed in distinctly red tinted sky to the east-south-east of Mutare. This phenomenon appears to be similar to the reflected dawning described at https://atoptics.wordpress.com/2015/02/01/red-sky-glow-by-reflected-dawning/ except that it is occurring at dusk. In this case the anti-sunset twilight glow is likely due to an evenly distributed horizon-to-horizon layer of stratospheric volcanic aerosols. This glow, which has been called “volcanic gegenschein” by Spaceweather Gallery contributor Tara Williams, has also been observed in NSW Australia https://spaceweathergallery.com/indiv_upload.php?upload_id=185513
