20 ve 21 Ekim geceleri, Orionid g\u00f6kta\u015f\u0131 ya\u011fmurunun en yo\u011fun oldu\u011fu d\u00f6nem. Ya\u011fmurun zirve noktas\u0131 ise 21 Ekim\u2019de TS\u0130 15.00\u2019te ger\u00e7ekle\u015fecek. Bu nedenle 20\/21 ve 21\/22 Ekim geceleri g\u00f6zlem yapmak i\u00e7in en uygun zamanlar olarak \u00f6ne \u00e7\u0131k\u0131yor.<\/p>\n
Bu y\u0131lki zirvede Ay \u201cyeni ay\u201d evresinde olacak, yani g\u00f6ky\u00fcz\u00fc karanl\u0131k ve net g\u00f6r\u00fcnecek. Bu da g\u00f6kta\u015flar\u0131n\u0131 \u00e7\u0131plak g\u00f6zle izlemeyi kolayla\u015ft\u0131racak. Uzmanlara g\u00f6re Orionid ya\u011fmuru, Ay\u2019\u0131n parlamad\u0131\u011f\u0131 y\u0131llarda en keyifli h\u00e2lini al\u0131yor.<\/p>\n
