While distracted by (1) Ceres and (2) Pallas, I failed to notice that currently, (7) Iris has the greatest apparent brightness of any asteroid in our sky. It's at magnitude 6.9 now, so it's readily accessible to a binocular observer. On top of that, it's position in Aries means that it can be easily located, about 1°42' east of Sharatan (Beta Arietis) at 9 pm tonight (02-Nov-2017) when it will be about 45° altitude. I've attached a clip from a SkyTools chart showing tonight's position.

I went to my slightly-less-suburban site, Swede Run in Mooretown, NJ, on Thursday evening, 02-Nov-2017, for a look at (7) Iris. Using 15x56 binoculars, it was easily spotted near the stick figure of Aries, despite the presence of high, thin clouds and a nearly-full moon just 17° away. I've attached an annotated snapshot; a mouseover version and more information is available on my web page.
