3月30日，在地球北半球六月湖上空漆黑的夜空中，12P/庞斯-布鲁克斯彗星正矗立在西方地平线上。它扭曲的湍流离子尾巴和弥漫的绿色彗发被捕获在这张2度宽的望远镜视野中，与明亮的黄色恒星Hamal也被称为阿尔法羊尾星。现在，庞斯-布鲁克斯已经离开了北方的夜晚，在4月21日接近近日点。4月8日，你仍然可以在白天的天空中看到这颗彗星。但要做到这一点，你必须站在日全食的道路上，把目光从诱人的日冕和完全日食的景象中移开。NASA报道：2024年4月8日的日全食

In dark evening skies over June Lake, northern hemisphere, planet Earth, Comet 12P/Pons-Brooks stood just above the western horizon on March 30. Its twisted turbulent ion tail and diffuse greenish coma are captured in this two degree wide telescopic field of view along with bright yellowish star Hamal also known as Alpha Arietis. Now Pons-Brooks has moved out of the northern night though, approaching perihelion on April 21. On April 8 you might still spot the comet in daytime skies. But to do it, you will have to stand in the path of totality and look away from the spectacle of an alluring solar corona and totally eclipsed Sun. NASA Coverage: Total Solar Eclipse of 2024 April 8
