Uranus: August 8, 2012F. Colas, J. L. Dauvergne, M. Delcroix, T. Legault & C. ViladrichPic du Midi 1.0 m telescope
uranus belt latitudes
Uranus Belt Latitudes
  • Equatorial Belt
    • 2° S to 13° N (3° uncertainty)
  • North Temperate Belt
    • 45 3° N to 59° N (3° uncertainty)
photometry
Photometry
  • Measurement of Brightness
  • Accurate brightness measurements since 1950
  • B, V, R and I filters
photometry uranus
Photometry: Uranus

V(1,a) = -7.117 ± 0.007

B – V = 0.47

R – V = 0.307

I – R = 1.18

*Uranus is a little fainter than in the previous apparition

photometry neptune
Photometry: Neptune

V(1,a) = -7.005 ± 0.009

B – V = 0.384

photometry oberon
Photometry: Oberon
  • September 24, 2012 unfiltered image:
    • Titania was 0.25 mag. brighter than Oberon
conclusions
Conclusions
  • Several astronomers have imaged albedo features on Uranus using telescopes as small as a C11.
  • Uranus is a little fainter than in the previous apparition
