349. On 4 July you observe the lower limb of the Sun at a sextant altitude (hs) of 25° 29.8'. The index error is 3.1' off the arc. The height of eye is 48 feet (14.6 meters). What is the observed altitude (Ho)?

The observed altitude is calculated by applying the index correction, subtracting the dip correction for the height of eye, and adding the Sun's lower limb main correction from the Nautical Almanac to the sextant altitude, resulting in 25 40.2'.
