SATURN NORTH HEMISPHERE WHITE SPOT ALERT
On December 10, 2010 between 18:01 and 18:13UT Anthony Wesley of Murrumbateman, Australia submitted
several images at visual and IR wavelengths of a prominent white spot situated in the North Tropical
Zone (NTrZ) using a 36.8cm (14.5in) Newtonian.
Likewise, Marc Delcroix of Tournefeuille, France submitted several images at various wavelengths of
the NTrZ white spot using a 25.4cm (10.0in) SCT.
Data derived from these images suggest the NTrZ was located roughly at longitude 255° and Saturnicentric
latitude around 33/33.5°.
The NTrZ storm may be bright enough to be detected visually with sufficient aperture and good seeing.
Observers are requested to begin submitting their observations and images to the ALPO Saturn Section
as soon as possible.
