Yesterday I took some images of this comet with the 0.35-m LCO telescope at SAAO. Iíve attached one, unprocessed, uncropped, roughly 15x15 arcminutes. The comet is rather prominent on the images, which led me to attempt a visual observation last night. I successfully detected it, although itís fainter than what the LCO images seemed to suggest:

August 21.27 UT, m1 = 13.2, 1.4í coma, DC ~3 (41 cm reflector, 70x)

I donít know if this is an outburst or not. Itís much brighter than what it was at perihelion passage almost four months ago; on the other hand, it is presently at its closest approach to Earth, and will be at opposition next month.
