Forbidden Ca II in the sun unmasked by way of VenusEleven high dispersion spectra of Venus, taken with blue Doppler shifts, have been used to unmask the 7323.88 angstrom forbidden line of Ca II from the earth atmospheric H2O absorption line at 7323.972 angstroms. An equivalent width for the Ca II line has been obtained in integrated sunlight. A model giving the solar calcium abundance is presented.
