TL;DR
This paper reports R-band observations of comet C/LINEAR (2004B1) between 2 and 3 AU from the Sun, analyzing surface brightness, light curves, and coma morphology changes over a two-month period.
Contribution
It provides detailed observational data and analysis of the comet's coma and brightness variations during its approach at 2-3 AU heliocentric distance.
Findings
Brightness decreases observed over several days.
Morphological changes in the coma during brightness drops.
Surface brightness and radial profiles characterized.
Abstract
We present R-band observations of comet C2004B1 obtained in the period June, 21 - August 20, 2006. The data have been reduced to surface brightness maps, light curves, and mean radial profiles of the coma. In two cases a decrease of the brightness was recorded, which lasted for several days. The brightness decrease was accompanied by morphological changes in the coma.
