Hlavn\u00edm c\u00edlem byla bezpochyby kometa C\/2021 A1 Leonard<\/a>. Je to prvn\u00ed objeven\u00e1 kometa leto\u0161n\u00edho roku a z\u00e1rove\u0148 tak\u00e9 nejjasn\u011bj\u0161\u00ed.

Jak pravil jeden astronom z Liberecka (ve slu\u0161n\u011bj\u0161\u00edm p\u0159espisu): “Kv\u016fli blb\u00fd komet\u011b nebude vid\u011bt kulovka M3”. Na\u0161t\u011bst\u00ed se t\u011bsn\u011b minuly, tak\u017ee nikdo nebyl zklam\u00e1n. Kulov\u00e1 hv\u011bzdokupa M3 p\u0159ed\u010dila svoj\u00ed jasnost\u00ed (6,2 mag) pomyslnou komet\u00e1rn\u00ed n\u00e1v\u0161t\u011bvnici (cca 6,5 – 7 mag). Vlasatice m\u00e1 aku\u00e1ln\u011b rychl\u00fd pohyb po obloze, co\u017e bylo dob\u0159e znateln\u00e9 v\u016f\u010di kulovce. Kometa Leonard nakonec pravd\u011bpodobn\u011b z\u016fstane za optimistick\u00fdm v\u00fdhledem v\u00fdvoje jasnosti (m\u016f\u017ee je\u0161t\u011b p\u0159ekvapit), ale i tak je velice p\u011bkn\u00e1. Hlavn\u011b jej\u00ed dlouh\u00fd a viditeln\u00fd ohon ji pasuje dle m\u00e9ho n\u00e1zoru do pozice leto\u0161n\u00ed v\u00edt\u011bzky.<\/p>\n

Dal\u0161\u00ed v po\u0159ad\u00ed byla kr\u00e1tkoperiodick\u00e1 67P\/\u010curjumov-Gerasimenkov\u00e1<\/a>, kter\u00e1 se nach\u00e1z\u00ed v souhv\u011bzd\u00ed Raka.
