Direct Distance Measurements to SN2009ip
  We demonstrate the applicability of our new method (the Dense Shell Method or DSM) for the determination of astronomical distances by calculating the distance to SN2009ip. The distance to this supernova has been accurately determined in the standard approach via the cosmic distance ladder and has been found to be 20.4 Mpc. Our direct method, assuming the most reasonable parameter values, gives a very close result, namely 20.1+/-0.8 (68% CL) Mpc to SN2009ip.
