Here's a little better image of SN 1998s from last night (98 Mar. ... I went crazy last night trying to get an image of the new SN without a lot of scattered (the streak of light above the galaxy) light from Chi UMa which is close by. I'm going to change a few things in my camera/reducer setup an try again on the next clear night. I'll send you a better image then. ... Back to Supernovae in NGC and IC galaxies . Back to Supernova 1998S images . ...

... The distance scales of the objects are matched both by comparing the first derivatives of the angular velocity determined separately from radial velocities and proper motions and by the statistical-parallax method. ... Good agreement between the inferred 0 and our calculations based on space velocities suggests that the Lindblad relation holds throughout the entire sample volume. ... Brandt and Blitz (1993) published the distances and radial velocities for a total of 206 H II-regions. ... Astron. ...
