WHAT GOING ON WITH C 2010 /X1 ELENIN ?

Leonid Elenin is inquiring anbout light curve similarities to thsi comet though it is estimated that c 2010 /x1 's nucleus [4Km] is 10 times larger than comet linear [.44 km]......see comet Comet LINEAR (C/1999 S4)breakup in July Aug 2000


HUBBLE JULY 4-7 NUCLEUS BEGINS NON TIDAL BREAK UP!

HUGE X RAY EMISSION SURVEYED 14-15 JULY

Using soft x-ray observations of the bright new comet C/1999 S4 (LINEAR) with the Chandra x-ray observatory, we have detected x-ray line emission created by charge exchange between highly ionized solar wind minor ions and neutral gases in the comet's coma. The emission morphology was symmetrically crescent shaped and extended out to 300,000 kilometers from the nucleus. The emission spectrum contains 6 lines at 320, 400, 490, 560, 600, and 670 electron volts, attributable to electron capture and radiative deexcitation by the solar wind species C+5, C+6, N+7, O+7, and O+8. A contemporaneous 7-day soft x-ray light curve obtained using the Extreme Ultraviolet Explorer demonstrates a large increase in the comet's emission coincident with a strong solar flare on 14 and 15 July 2000.

DISINTEGRATION COMPLETE 18-19 JULY

We analyzed photometric measurements and images of comet C/LINEAR before perihelion and after its breakup. Results from our photometry data include a lower limit of 0.44 kilometer for the radius of the nucleus before breakup, and a determination that it was depleted in carbon-chain molecules relative to most other comets. Our imaging and modeling results, which include a constraint on the rotational state of the nucleus, indicate that the disintegration likely started on 18 or 19 July 2000. The total mass detectable in the dust tail after the breakup was 3 × 108 kilograms, comparable to one of the fragments in the Hubble Space Telescope images; we therefore infer that most of the comet's original mass is hidden in remnants between 1 millimeter and 50 meters in diameter.
