As told in the June 2013 Sky & Telescope, on the morning of June 12th a 6.4-magnitude star in southern Ophiuchus east of Antares will wink out for up to 4 seconds along a track from Oklahoma across northwest Texas, southern New Mexico, and southern Arizona, when it is occulted by the small, faint asteroid 332 Siri.

Here are a map of the track, finder charts for the star, predicted times, and more details.

Looking beyond, here is Steve Preston's pick of the best asteroid occultations worldwide for 2013.

And Preston's master list of asteroid occultation predictions.

For actual human advice and help, join the International Occultation Timing Association (IOTA) Yahoo discussion group, say hi, and ask for help.

Here are results of past timing campaigns (in the "Results of Observations" box at top).
