# download_IERS_A

astroplan.download_IERS_A(show_progress=True)

  Download and cache the IERS Bulletin A table.

  If one is already cached, download a new one and overwrite the old. Store table in the astropy cache, and undo the monkey patching caused by earlier failure (if applicable).

  If one does not exist, monkey patch `_get_delta_ut1_utc` so that `Time` objects don’t raise errors by computing UT1-UTC off the end of the IERS table.

  Parameters
    show_progress bool

      `True` shows a progress bar during the download.
