Looks like it. Not the first time a comet has seemed to create a CME at the moment of impact. ISON is much more massive but “suppose” to miss.
ISON is supposed to approach the Sun within 750,000 miles or so. The nucleus of the comet is three miles across, compared to this little guy yesterday that was estimated to have been only a few tens of meters across. If Jupiter could rip Shoemaker-Levy apart, what will the Sun do to ISON when it approaches so closely? As it stands now, ISON isn’t supposed to approach the Earth any closer than 40 million miles, but that’s assuming it leaves the inner solar system in one piece. The odds of any piece of it hitting us is probably slim, but it’s got my attention!
