About this image

Yet another small satellite in the outer solar system. The MPC ephemeris was used to stack the subs on the predicted motion (-13.93 arcsec/hr in RA, -1.80 arcsec/hr in Dec) of Carme which is why the stars are trailed slightly.  The predicted magnitude is V=17.6

As with the earlier image of Pasiphae, the contrast is poor because of brilliantly moonlit Saharan dust. Seeing wasn't wonderful either, at about 5-6 arcsec FWHM.

Jupiter now lies in a rich area of the Milky Way as is evident in the  image provided. A precise position and careful examination of the DSS2 images are needed for an unambiguous identification of its fainter satellites, as is an element of luck if the satellites are not to be blended with a background star of comparable or greater brightness.
