Today, #Comet Tsuchinshan-ATLAS (C/2023 A3) is making its closest approach to the sun (0.40 AU). A surge of solar heat is making the comet visible in dawn twilight. Fritz Helmut Hemmerich sends this picture from #Tenerife, the Canary Islands:

"A small gap in the morning cloud over the Atlantic Ocean between Tenerife and Gran Canaria gave me the chance to get my first image of this promising comet," says photographer Fritz Helmut Hemmerich. "This is a 60x0.8s exposure using my Sony A7MIII camera (ISO 6000)."
