Image processed of nucleus of surface of comet 67P/CHURYUMOV-GERASIMENKO

I just process the image of the surface of the nucleus of Comet 67P / Churyumov-Gerasimenko, ESA has placed at last an open kernel image file, I used to make one of them, very curious, because it shows an image of a plume important ice is highly reflective, the projected shadow can give an idea of how high is, likewise in the area of volatile ice deposits on the surface are, I hope you like it.

Analysis of the reduced light curve of comet C/2014 Q2 LOVEJOY , Water rate production , Fraction active surface , Masses estimated .

I estimate the masse for a comet C/2014 Q2 LOVEJOY , the diameter of the nucleus , maximun water rate production in the perihelion , and active surface fraction , this calculations is based in 3.200 observations from database MPC/IAU , and personal elaborating light visual and ccd curve of comet along time of near 1 year of work , the down graphic is reduced for geocentric distance in y axis , and x axis the heliocentric distance in au , this work is new analysis for comet C/2014 Q2 LOVEJOY and contain great quantity of observations . The introduction physical's parameters of Mn ( masse) , log Q(H2O) , f , and D , the results , is Max log Q(H2O) = 10e 28.58 mol s-1 ( 1000 kg/sec. ) , log 10 Mn ( kg) = 11.6 , D = 1.0 km , f = 2.3 .

HISTORIC ANALYSIS OF THE LIGHT VISUAL AND CCD CURVE OF COMET 29P/SW-1 1932-2015

Probability new discovery of Comet 29P / SW-1, based on a comprehensive analysis of 5,169 visual observations, and ccd Comet 29P / SW-1, in the period 1932-2015, the photometric analysis of the light curve by Pina JPNavarro shown in the 29P / SW-1 comet an average drop in outburts or explosions brightness a 2.0 magnitude in the last 20 years observed, from 1995-2015, the most likely hypothesis is that this comet exhibits a wear materials + CO gas and dust core level important.

UPDATE LIGHT VISUAL AND CCD CURVE OF COMET C/2014 Q2 LOVEJOY ( analysis VI )

Hi all , updated the light visual and ccd curve of comet C/2014 Q2 LOVEJOY , have been collected analyzed and graphed after 10 months of hard work rewarded after the publication of my analysis in the American magazine Sky and Telescope and hitting the forecast of maximum brightness for this comet after reaching visual magnitude +4 was the first analyst curves global warning light turn on the brightness of the comet, my upgrade is the largest and most comprehensive global visual light curve of this comet with 3,083 observations of all the observatories and observers of comets . Reduced light visual-ccd curve of comet C/2014 Q2 LOVEJOY , mred= m1-5 log (d) vs log R , the analysis show why the comet is more brightness in post-perihelion .
