C20 Light Curve
You have discovered a Cepheid! Ferrarese et al. (1996) named
this Cepheid C20. Below is their plot of C20's light curve. On Part
I, Section B of your lab sheet, record the name of the Cepheid, its
grid section number (74), its average
apparent V magnitude (mv), and its period (P). (Careful: the numbers
decrease going up the vertical axis!) When you're done, return to the main grid section 74 page to look
for another Cepheid, or return to the
main WF4 8x8 grid.
