Today we have been able to image again comet 174P/Echeclus with the 2-m Faulkes Telescope South to follow the recent bright phase of this interesting centaur.
Stacking of eight R-filtered exposures, 60-sec each, obtained remotely, from the Faulkes Telescope South on 2011, June 24.5, through a 2.0-m f/10.0 Ritchey-Chretien + CCD, shows some evolution in the morphology of this comet: the parabolic coma previously reported, albeit present, is now much fainter, and shows its ADU counts very close to the sky background limit. No other details, except a nuclear condensation having an m2 close t R about 18.9, are currently visible in our images.
