Five SiC and two graphite presolar grains exhibit isotopic ratios characteristic of ONe nova nucleosynthesis: low 12C/13C (4-9), low 14N/15N (5-20), high 26Al/27Al, high 30Si/28Si (2/×solar) with close-to-normal 29Si/28Si. The upper limit of 20Ne/22Ne (<0.01) of one graphite grain suggests that the 22Ne excess is due to the decay of 22Na. In order to achieve the isotopic ratios of the grains, however, synthesized material during nova explosion had to be mixed with isotopically close-to-solar material, which should consist of more than 95% of the mix.
