This stunning photograph of the lunar rainbow and the lunar Brocken Spectre amidst the night sky was captured from Mount Tsubakuro located in Japan’s Hida Mountains in Nagano. Both these atmospheric occurrences are due to the moon’s light being reflected and refracted from water droplets. A lunar rainbow or a moonbow is a rare phenomenon that occurs with the right settings of a bright full moon which is less than 42° high, rain on the opposite side of the moon and a dark night sky. The Brocken Spectre is named after the highest peak of the Harz mountain range in Germany, where it was first recorded. Here it is seen from the summit as a magnified shadow of the observer cast onto the cloud surrounded by a glory consisting of concentric circles centered at the point directly opposite the bright moon in the background.

الفئة: هالات الشمس / القمر.
توصيف الصورة : الصورة المذهلة لقوس قزح القمر وتوضح التشتت الطيفى لضوء القمر فى الغلاف الجوى للارض .
واخذت الصورة وسط سماء الليل من جبل تسوباكورو الواقع الواقع في جبال هيدا فى مدينة ناجانو اليابانية.
تلك الظاهرة تحدث فى الغلاف الجوى وترجع ظهور تلك الهالة حول القمر إلى انعكاس ضوء القمر وانكساره من قطرات الماء.
وتعتبر ظاهرة قوس قزح القمر أوكما تعرف بقوس القمر ظاهرة نادرة ترى فى السماء المظلمة وتحدث عندما يكون القمر كامل السطوع فى طور البدر وعلى ارتفاع افل من 42 درجة وفى وجود قطرات الماء او المطر على الجانب الآخر من القمر..
وقد تم تسمية Brocken Specter على اسم أعلى قمة في سلسلة جبال Harz في ألمانيا ، حيث تم رؤيته وتسجيله لأول مرة.
هذا وترى الهالة حول القمر كسحابة تتكون من دوائر متحدة المركز عند النقطة المقابلة مباشرة للقمر الساطع في الخلفية.

Questa splendida fotografia dell'arcobaleno lunare e dello spettro lunare di Brocken nel cielo notturno è stata scattata dal monte Tsubakuro, situato sulle montagne Hida in Giappone, a Nagano. Entrambi questi fenomeni atmosferici sono dovuti alla luce della luna che viene riflessa e rifratta dalle gocce d'acqua. L'arcobaleno lunare o moonbow è un fenomeno raro che si verifica con le giuste condizioni: una luna piena luminosa con un'altezza inferiore a 42°, pioggia sul lato opposto della luna e un cielo notturno scuro. Lo spettro di Brocken prende il nome dalla vetta più alta della catena montuosa di Harz, in Germania, dove è stato registrato per la prima volta. Qui è visto dalla cima come un'ombra ingrandita dell'osservatore proiettata sulla nuvola, circondata da una sorta di corona costituita da cerchi concentrici centrati nel punto direttamente opposto alla luna luminosa sullo sfondo.
