| Following the theme that several earth-approaching minor
planets have four-letter masculine names, this object bears the first
name of the discoverer. The discoverer is also honored by minor planet
(1726). |

Images of Cuno |
|
|
The collage on the left shows images obtained on December 18. The first 6 images span about slightly more than 30 minutes, then there's a gap of about 22 minutes, followed by five more images that span about 25 minutes. There is a hint of interesting radar-dark structure near the center of several of the images in roughly "broadside" orientations. Lightcurves indicate that Cuno has a rotation period of 3.56 hours, so the image sequence shown here spans about 140 degrees of rotation. |

The collage on the left shows images obtained on December 19. The sequence extends from 09:16:30 - 11:38:12 UTC and covers about 240 degrees of rotation. The final six images overlap rotation phases seen in the first six images on December 18. Several of those images show a radar-dark feature near the center of the echo; that feature may be a concavity roughly 1-2 km in diameter. |

The collage on the left shows images obtained on December 21. The sequence extends from 09:52:43 - 11:59:47 UTC and covers about 215 degrees of rotation. There is subtle structure along the leading edge in several images but the radar-dark feature that is so prominent in December 19 images is not obvious in the December 21 images, probably because the Dec. 21 images did not cover the longitudes where the radar-dark feature was seen. |
