I will only state the facts.

Create a five-panel historical manga illustration about astronomer Clyde Tombaugh's reported UFO sighting on August 20, 1949, in Las Cruces, New Mexico. Visual style: Semi-realistic anime manga / historical comic illustration. Clean expressive linework, cel-shaded colors, cinematic composition, detailed but clearly illustrated rather than photorealistic. 1940s American atmosphere. Dark blue night sky, restrained colors, realistic proportions with anime-style facial rendering. Serious and mysterious mood, not comedic. Avoid photorealism. Do not depict a recognizable full portrait of Clyde Tombaugh. His face should only appear partially, with his identity conveyed through clothing, posture, eyeglasses, and context. Panel 1: 1949 Las Cruces, New Mexico, at night. A slender middle-aged male astronomer stands in his backyard, seen from behind, looking up at the starry sky. He wears simple 1940s American clothing and eyeglasses. A modest house and backyard fence are visible. His face is completely hidden. Panel 2: Extreme close-up of the astronomer's eyes and upper nose. He wears period-appropriate eyeglasses. His eyes suddenly widen in genuine surprise. A faint pale blue-green reflection of the mysterious rectangular lights appears on one eyeglass lens. Do not show the entire face. 博士「え！？……」 Panel 3: Point-of-view shot looking into the dark night sky. Approximately 6–8 small pale blue-green rectangular luminous shapes are arranged in a rigid geometric formation and move silently across the sky. They should look like distant glowing windows rather than a recognizable spacecraft. No flying saucer, no visible spacecraft body, no alien, no beams, no flames. The strange geometric arrangement is the main visual focus. 博士「なんだ！？あれ！？」 Panel 4: Close-up showing only the lower half of the astronomer's face, from below the nose to the chin, with part of his cheek visible. His mouth is slightly open and a small amount of sweat is visible. His expression conveys intense concentration and confusion rather than exaggerated fear. His observations appear as dialogue: 博士「6～8個……」 博士「淡い青緑色……」 博士「窓？……」 博士「幾何学？……」 博士「天頂付近……南……南南東……」 博士「約35度……」 博士「消失！？……」 Panel 5: The mysterious lights have completely disappeared. The astronomer is again seen from behind, standing motionless in his backyard and staring silently at the empty starry sky. Quiet, spacious composition with strong negative space and lingering mystery. 博士「……。」 Below the five panels, add a cream-colored historical explanation section titled: 「1949年8月20日の目撃事件の詳細」 Use Japanese text explaining: ■ 時刻：1949年8月20日、約23時（午後11時頃） ■ 場所：アメリカ合衆国ニューメキシコ州ラスクルーセスの自宅裏庭 ■ 目撃者：クライド・トンボー博士（天文学者・冥王星発見者） ■ 概要： 1949年8月20日、冥王星を発見したことで有名な天文学者クライド・トンボー博士は、ニューメキシコ州ラスクルーセスの自宅裏庭で、不可解な光を目撃した。 時刻は約23時。博士は空のほぼ天頂付近に、淡い青緑色の矩形の光が6～8個、幾何学的に整列した状態で南から移動しているのを見た。それらの光は南から南南東方向へ進み、高度が下がるにつれて小さくなり、約35度の高度で突然消失した。目撃時間はわずか数秒間だった。 博士は直ちに観測記録を取り、後に報告した。 博士はこの現象を宇宙船だと断定せず、自然の光学現象などの可能性も考え、慎重な姿勢を貫いた。トンボー博士にとっても、この夜の出来事は長年の観測経験の中で説明がつかない、特別な体験だった。 Important: The mysterious phenomenon must remain unidentified. Do not depict it as a conventional flying saucer or alien spacecraft. The pale blue-green rectangular lights are distant, faint, geometrically arranged, and silent. Maintain historical 1949 atmosphere throughout. All dialogue and explanatory text must be in Japanese. Do not add unrelated dialogue or text.
