The #Jupiter #Venus #Mercury view from Regensburg 5 minutes later today, with the latter 4 1/2 degrees up - soon thereafter Mercury would be lost to extinction for the naked eye.

The planets #Jupiter #Venus #Mercury (in the gap between trees in the lower right) again, on 7 June from the #Eschenberg in the #BavarianForest where a public observatory with a 1-meter (!) telescope is under construction: https://bayern.naturparke.de/2026/04/29/baustart-fuer-die-naturpark-sternwarte-bayerwald/ - the much smaller telescope here is pointed at Jupiter.

Three #planets in the evening sky over #Regensburg, Germany, today, when the Sun was 9° below the horizon and #Mercury - in the lower right, above the crane - 5° above the horizon. At that time it was also an easy naked-eye object, joining the pair of #Jupiter and #Venus on the left. After some rain during the day the atmosphere was superbly clear!
