  1. Rank 76 Occultation of Regulusby (1669) Dagmar, 2015 May 24 2014 July 13 32nd Annual IOTA Meeting University of Maryland Observatory College Park, MD David W. Dunham

  2. It will occur in THIS AREA! But . . .

  3. It will occur in THIS AREA! But . . The Sun alt. will be 71

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

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

  6. 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

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

  8. 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.

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

  10. 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 • HaithemAltwaijry 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
