object DV Boo

Správné elementy pro DV Boo jsou M = 48045.254 + 3.78264*E. V minulosti byly omylem duplicitně uváděny i předpovědi pro neplatné elementy 52720.588+1.26086*E. Děkuji M. Zíbarovi za upozornění.

Minimum asi velmi dlouhé a nastává zcela mimo elementy (52720.588+1.26086*E),měřeno 27.2.2011
