IOTA Occultation Campaigns

Each year IOTA will identify at least two occultation events in North America as special observing campaigns for the year.  One event will be chosen for the potential to generate the most valuable results, and the other event will be chosen as the most “observable”.  We encourage IOTA observers to put these events on their calendar.  Given the high priority for these events, we expect some observers will travel to observe these events. Prior to each event, someone in IOTA will post messages to the Yahoo group informing everyone of the weather prospects and possible preferred locations for observers.

2019 Sep 26, 9:54 UT: (598) Octavia Occults 7.5-mag. SAO 80087

This occultation by (598) Octavia is the North American “most observable” event for 2019 since the prediction has good statistics with a medium-size asteroid visible along a path including many large cities across the USA. More details about the occultation can be found at http://www.asteroidoccultation.com/2019_09/0926_598_62682.htm and via OccultWatcher once the event appears there. Note that this occultation will occur about 5 days after the 2019 IOTA annual meeting at Camp Oakes in southern California. It was difficult to select the “most observable” event; some other very good events deserving observer’s attention are listed, with links for more information, at the bottom of this page.

2019 Oct 24, 6:08 UT: (16) Psyche Occults mag 10.2 star

This occultation by (16) Psyche is the North American “most valuable” event for 2019 since the asteroid, the largest metallic asteroid, is the target of a NASA mission, also called Psyche. More details about the occultation can be found at http://www.asteroidoccultation.com/2019_10/1024_16_62878.htm and via OccultWatcher once the event appears there.

Some other very good events during 2019

  • 2019 Aug 28 / (624) Hektor / mag SAO 10.7 over Monterrey, Brownsville, Miami, & Seville-ES http://www.asteroidoccultation.com/2019_09/0925_493_62680.htmHektor is the largest Trojan asteroid, a contact binary object that also has a small satellite, so this is a runner-up for the most valuable asteroidal occultation of 2019
