Anybody know how accurate the splining is given the data sets available?
These polar maps show the first global, topographic mapping of Saturn’s moon Titan, using data from NASA’s Cassini mission. To create these maps, scientists employed a mathematical process called splining, which uses smooth curved surfaces to “join” the areas between grids of existing topography profiles obtained by Cassini’s radar instrument. The topography maps at bottom focus on the polar regions (north at left, south at right) in stereographic projection. The top maps show the 2-D radar data in gold and black, with topography data color-coded by elevation. The bottom images are from the new topography map, with contour lines added at 656 feet (200 meters) apart in elevation.
Visible are deep basins at 72 degrees south latitude and 20 degrees east longitude, and a wider basin at 68 degrees south latitude and 105 degrees east longitude.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and ASI, the Italian Space Agency. JPL, a division of the California Institute of Technology in Pasadena, manages the mission for NASA’s Science Mission Directorate, Washington. The radar instrument was built by JPL and the Italian Space Agency, working with team members from the US and several European countries.

Hubble and the Large Binocular Telescope teamed up to take a new and very close look at the well known planetary nebula M57 or The Ring Nebula.
It looks like the “Ring” is just a matter of perspective and it really is more like looking down a barrel.

Dance of the Planets: An Evening Under the Stars
Saturday, June 1, 2013
8:00 PM – 10:00 PM
Pier 1 at Brooklyn Bridge Park
Brooklyn, NY 11201
“Dance” under the stars and join professional and amateur astronomers for a free evening of urban stargazing. It’s an outdoor party beneath the Brooklyn Bridge and the twinkling canvas of the night sky, and a night to explore and discover the vast wonders of the cosmos. Bring your telescope if you have one, or use one of the dozens we’ll have on hand.
Enjoy conversations with leading astronomers and live music to celebrate the astronomical event “Dance of the Planets,” at this communal stargazing experience. The festivities will feature astronomy groups from around the Tri-State Area, family-friendly activities, twilight sailing of the Schooner Mystic Whaler, refreshments, local food trucks, and more.

SUBJ: IPS GEOMAGNETIC DISTURBANCE WARNING 13/07ISSUED AT 0300UT/18 MAY 2013
BY THE AUSTRALIAN SPACE FORECAST CENTRE.
Aurora could potentially be seen as far north as southern Victoria and Northern New Zealand.A full halo earthward directed CME was observed on 17-May. This may increase geomagnetic activity to Minor Storm levels, with periods at Major storm level from mid 19-May and into early 20-May. The magnitude of the storm will depend on the orientation of the magnetic field in the CME.
INCREASED GEOMAGNETIC ACTIVITY EXPECTED DUE TO CORONAL MASS EJECTION FROM 19-20 MAY 2013 ___________________________________________________________
GEOMAGNETIC ACTIVITY FORECAST
19 May: Minor Storm
20 May: Active to Minor Storm
