    ► New calculation of geomagnetic effects on cosmic rays. ► New calculation of the one-dimensional moon and sun shadow. ► Hints of interplanetary magnetic field effects on cosmic rays. ► Absolute astrophysical pointing calibration of the MINOS far detector. The shadowing of cosmic ray primaries by the moon and sun was observed by the MINOS far detector at a depth of 2070 mwe using 83.54 million cosmic ray muons accumulated over 1857.91 live-days. The shadow of the moon was detected at the 5.6 σ level and the shadow of the sun at the 3.8 σ level using a log-likelihood search in celestial coordinates. The moon shadow was used to quantify the absolute astrophysical pointing of the detector to be 0.17 ± 0.12°. Hints of interplanetary magnetic field effects were observed in both the sun and moon shadow.
