Stellar Occultations of Delta Aries (Aug 21) and 37 Taurus (Aug 22)

After the exciting occultation of Pi Sagitarii on the 10th, and Kappa Pisces on the 16th, now America will still see yet another occultation - or should I remark two. Two lovely, 4.4 magnitude stars will occult first, for the Whole United states and Canada, and the next day, just for the eastern US and Europe & Africa.

AUGUST 21, 2011: STELLAR OCCULTATION OF DELTA ARIES

The moon made viewing difficult these past two occultations, but now, as the moon is becoming new, viewing conditions should improve. During the occultation of Delta Aries, the moon will be waning, and will be 56% illuminated, which although still poor, is better than Kappa Pisces' occultation. Actually, this star's magnitude is 4.35, rather than the estimated 4.4, but even with the moon this bright, don't wait to see anything great. Wait until the moon is new - like the upcoming occultations below. Below is a visibility map and data.


AUGUST 22, 2011: STELLAR OCCULTATION OF 37 TAURUS

If weather permitted you to view the occultation on the 21st and you live in the south-east of the US or Europe or Africa, try watching the star 37 Taurus occult instead. With a magnitude of 4.36, and the moon being 46% bright, this occultation will definitely be better than yesterday's occultation. Below is a visibility map and data.
