RECON Campaign involving Chiron!

Happy Fourth of July, RECON!!!

We wanted to provide a heads up about an exciting opportunity to measure Chiron, a 100-km Centaur with suspected ring structure(s)!  We will have an event page up shortly, but the map below provided by LESIA at L’Observatoire de Paris shows that the probabilities of successfully recording this object are high and that the extended RECON network down to Arizona is well positioned to map any extended structures associated with the main body!

The event will occur early on the morning of Tuesday, August 15 around 11:51 UT (4:51AM PDT/MST). Twilight will be approaching during the occultation, but there should be plenty of time to get onto the field prior to this. Mark your calendars now and stay tuned for details!

Observers Track New Horizons’ Next Target – Sky & Telescope

Sky & Telescope just published a nice article about last week’s Southern Hemisphere occultation involving 2014 MU69:

All teams on the campaign collected useable data which is currently being analyzed. A photo of RECON Team Member Robert Reaves from Parker, Arizona is included in the article.

RECON Contributes to Southern Hemisphere Campaign

This is an exciting week for RECON Principal Investigator Marc Buie as well as RECON team member Robert Reaves from Parker, Arizona.  Marc is leading a dual continent occultation campaign involving 22 telescopes being deployed in Argentina and South Africa to measure the shadow of 2014 MU69, the next target for the NASA New Horizons mission.  This Friday evening (2017 June 3 at 03:11:50 UT) 22 teams will be deployed on both continents for the first of three occultation opportunities this summer.

Marc invited RECON team member Robert Reaves to join one of these teams for this week’s event.  Both Marc and Robert are currently in South America prepping for the big event. For the next occultation opportunity in early July, Charlene Weisenborn from our Searchlight / Boulder City team will be participating as well.

Marc has been centrally in charge of working on predictions for these campaigns using Hubble and Gaia data.  In addition to observing form Argentina this week, he will also be flying aboard NASA SOFIA during the July event. According to Marc, our experience setting up the RECON network of over 50 telescope sites has been very valuable in prepping for these campaigns. Because 2014 MU69 is only thought to be around 30 km, the spacing of the network will be much tighter than RECON, with telescopes spaced roughly every 10 km rather than 50 km.

For more information, you can check out the New Horizon’s Webpage and the following post:  New Horizons Deploys Global Team for Rare Look at Next Flyby Target

Over the next six weeks, the New Horizons mission team gets an “MU69” preview of sorts – and a chance to gather some critical encounter-planning information – with a rare look at their target object from Earth.

Good luck, Marc, Robert, and all involved in Friday’s campaign!

This Week’s Spotlight: Sisters, OR

Get to know one of our 55 unique RECON communities!

Sisters, OR


Sisters is a charming town in central Oregon with a population of just over 2,000 people. Since Sisters joined in Spring of 2015, the team has grown to include students and teachers from Sisters High School and local community members. The team was initiated by retired park ranger Thomas Jeffrey, local teacher Rima Givot, and the Sisters Astronomy Club. Students Rylee Funk and Alex Burroughs have demonstrated strong leadership for this team. For more information about the Sisters team, check out their Instagram page below!
