The sun does not line up with the qibla today here.
Distance 2,979 mi · 4,794 km
At that moment stand an upright stick in the sun: its shadow points towards the qibla (or, when the sun is in the qibla direction, face the sun).
Phone compasses can be off by several degrees near metal, magnets or cars. Calibrate with a figure-8 and confirm with the sun or your masjid’s prayer rows.
