Finding the Distance to Supernova A

Use the process you just practiced to determine the distance to three supernovae (A, B and C). Here’s the first one:

Questions

  1. Fit the model light curve to your data. Then, move the dotted line to the peak of your light curve to determine the peak apparent magnitude. (Data from Zwicky Transient Facility)
