Bright Blaze In The Sky As India Saw It
The star-marker has a star by name Dhanushira to the South of another star called Dhanukoti. While the latter is found in almost all astrolabes (and is identified with a bright star called Alpha Oph, Arabic name Ras Alhague), Dhanushira is exclusive to this astrolabe. Its position matches with that of the 1604 supernova.
