Additional Notes:
At its distance of 25,100 light years, its angular diameter of 20' corresponds to a linear 145 light years. Nearby, about 40 arc minutes north-east of M13, is the faint (mag 11) galaxy NGC 6207, visible in many large- and medium-size-field photographs of M13, e.g., in the DSSM image. This galaxy has recently produced a type II supernova (SN 2004A).
