Notes:
This galaxy hosted SN 1999br (type II).
Observations:
C8 at 83x. A 12m star 30" N is murderous on the view! This is a faint and even
galaxy, with no obvious nucleus. A 13m star lies to the SE and may, in fact, be in the
line of sight with the halo.
Model (where the Sun is a baseball):
Its diameter would be 8 million miles.
