Narrative:
First officer was flying, we were cleared for a visibility short approach while on right downwind to runway 24R lax. Visibility appeared good with some haze and smog. While on final we lost visibility contact because of the sun lining up with the runway and striking the haze and smog. A missed approach was made. This situation could have been avoided if controllers were made more aware of the effect the sun has when it lines up as above, which in this case caused a quick reduction in visibility. They should not encourage visibility approachs as above and should alert flts to possible reduction in visibility when faced into the sun. Supplemental information from acn 144568. The ILS had been tuned and idented. The ILS signal was never received and when runway visibility contact was made the runway in sight was 25R.

Title: ACR LGT EXECUTES GO AROUND DUE TO VISIBILITY REDUCTION CAUSED BY WX CONDITIONS, SUN POSITION.
Narrative: F/O WAS FLYING, WE WERE CLRED FOR A VIS SHORT APCH WHILE ON R DOWNWIND TO RWY 24R LAX. VISIBILITY APPEARED GOOD WITH SOME HAZE AND SMOG. WHILE ON FINAL WE LOST VIS CONTACT BECAUSE OF THE SUN LINING UP WITH THE RWY AND STRIKING THE HAZE AND SMOG. A MISSED APCH WAS MADE. THIS SITUATION COULD HAVE BEEN AVOIDED IF CTLRS WERE MADE MORE AWARE OF THE EFFECT THE SUN HAS WHEN IT LINES UP AS ABOVE, WHICH IN THIS CASE CAUSED A QUICK REDUCTION IN VISIBILITY. THEY SHOULD NOT ENCOURAGE VIS APCHS AS ABOVE AND SHOULD ALERT FLTS TO POSSIBLE REDUCTION IN VISIBILITY WHEN FACED INTO THE SUN. SUPPLEMENTAL INFO FROM ACN 144568. THE ILS HAD BEEN TUNED AND IDENTED. THE ILS SIGNAL WAS NEVER RECEIVED AND WHEN RWY VIS CONTACT WAS MADE THE RWY IN SIGHT WAS 25R.
