It will occur in THIS AREA! But the Sun alt. will be 71 and star alt. only 2 !

It will occur in the same parts of southern Spain and Portugal where the 2005 Rhodope Regulus Occultation occurred But. . .

It will occur in the same parts of southern Spain and Portugal where the 2005 Rhodope Regulus Occultation occurred But the Sun alt. will be 31 and star alt. 53 , could pre-point in early am

The best place for this event is Saudi Arabia The star altitude will be about 67 with Sun altitude about -14

Maldive Islands – Regulus alt. 32 , Sun alt. -49 Deploying across the whole uncertainty zone has logistic problems and it can be quite cloudy, it’s not a desert. Path also in s. Sumatra, but star alt. only 1 there.

The best place for this event is Saudi Arabia YEMEN At Highway 10, the star alt. will be about 64 with Sun alt. -16

Conclusions The desert climate should give a high probability for observation in southern Saudi Arabia In Jeddah and Mecca, the event will be in twilight strong enough that I think students trained to observe might have trouble acquiring the star in time The sky will be dark enough to acquire Regulus easily at Hwy 10 Farther east approaches the border with Yemen where security may be a problem Haithem Altwaijry at King Abdulaziz City Science & Technical University has given papers on observing occultations of stars by NEO’s at space conferences; he has expressed an interest in collaborating with us to observe the event
