Hi Mark,
Might also add with regard to your comment on the solar flares that you read:

That’s not to say we won’t have a solar maximum in a year or so nor that we won’t have some strong solar flares and CME’s leading up to and during that solar maximum. Of course we will, but according to the best minds in the business, the Sun appears to be heading toward a quiet, if not dormant stage. This present solar maximum will probably be the quietest for about 100 years and the one after the present one may not occur at all. This comet, nor any others will have any effect on how the Sun behaves in this respect. Neither will they have any effect on the Sun's or Earth's magnetic fields or axis of rotation.
Neither is Elenin a "harbringer" of Nibiru -- which of course does not exist. If Nibiru existed and was passing through the inner solar-system within 12-15 months, it would currently be the brightest object in the sky save for the Sun and the Moon.
You may sleep peacefully at night!
Best,
Les D
