Details for (268) Adorea

Below are details for an optional RECON Main Belt Asteroid this Thursday evening.  Team members in Parker, Havasu, Mohave Valley, Bullhead/Laughlin, Kingman, and Searchlight are well situated for this event.  Feel free to sign up on OccultWatcher and/or let us know if you plan to observe.  Again, this is an optional event, but great practice and a targeted opportunity for the above teams to get a positive occultation measurement and create object profile!

Elektra: Main Belt Opportunity!

While we do not have any full network TNO campaigns scheduled this month, the map below shows a unique opportunity for all RECON teams in California, Nevada, and Arizona to celebrate Presidents Day by participating in an optional occultation campaign involving Main Belt Asteroid (130) Elektra!

Predicted shadow path for (130) Elektra

This event occurs February 16 around 08:37:00 UT, so after midnight on Monday evening/Tuesday morning (12:37AM Pacific Time and 01:37AM Arizona Time). The maximum event duration is 15.1 seconds and teams can read the predicted event time off the map above. Because Elektra (mag 11.8) is brighter than the star it is occulting (mag 12.3), the occultation will be very faint as the combined brightness drops by only half a magnitude. Tony George has offered to help with data analysis to generate light curves for participating teams.

John’s January Trip through Oregon

Map_Oregon_Winter2016Around the time of our last RECON campaign event, I had the opportunity to make a four-day road trip through our Southern Oregon and Northern California RECON sites. The map provided here highlights stops along the way. I landed at the Bend-Redmond Airport on Sunday, January 17. That evening, team members from Redmond, Bend, Sisters, Gilchrist, Sun River, and even White Swan all met at the Oregon Observatory. Despite the fact that it was snowing outside, it was a very productive opportunity to reconnect and talk through issues regarding RECON equipment and procedures, including our new procedure to take sky flats and dark field videos during future events.

The next day, I headed to Paisley, where I was joined by team members from Christmas Valley, Paisley, Lakeview, and Klamath Falls. Again, clouds kept us from practicing for Tuesday’s event, but it was useful for everyone to ask questions about equipment and alignment procedures.

Tuesday morning, I presented to middle school science students in Lakeview, and then I headed down to Fall River and Burney, California. That night, during the event involving 03WL7, the skies cleared around sunset allowing for a successful observation session with new team members from Burney. Sadly, most of the rest of the Western United States was clouded out that evening, and only four of our 55 telescopes sites had clear skies!

Chiloquin_RailstationAfter presenting to students in Burney on Wednesday morning, I stopped in on team members in Tulelake and Chiloquin. Marc and I had not made it to Chiloquin during our recruitment trips during Fall 2014, so it was great to visit this community.

Gilchrist_MarqueWednesday evening, I met with three team members in Klamath Falls The next day, I headed up to Gilchrist, the home of the Grizzlies, where I met with students that morning. This was the final RECON site that I had not yet had a chance to visit. In meeting with the students there, we had a great time discussing the RECON project and ways that students could be involved.

I wanted to thank the roughly 50 team members from 13 RECON communities who came out to meet with me during this trip. I am truly honored to work with such a great group of dedicated, flexible, and fun individuals!

Moon occults Aldebaran just before this week’s event

As RECON teams are setting up for our next campaign event involving Centaur 03WL7 this Tuesday evening, which begins around 7:30PM Pacific (2016 January 20 03:28 UT), they will be treated to an added bonus as the Moon passes in front of the bright red star Aldebaran around 6:20 Pacific (02:20 UT). This will definitely worth checking out if you have clear skies!

For a better look at sky forecasts, check out our Sky Conditions Page. While things look pretty socked in throughout Washington, there is a chance for clearing just in time for the event throughout the remainder of the network!

We recommend all teams print and go through the event page for Centaur 03WL7. Some teams have had difficulty with resetting the Capture Pin as described in Step 4 of the Camera Settings Guide. If you end up with a green screen, you can go back to using default screen size for this event until we’ve had a chance to provide a workaround.

Good luck to all!

Happy New Year RECON!

Welcome to 2016!!!

Wanted to share a recent asteroid occultation that occurred just before the New Year. On 2015 December 30 UT, main belt asteroid (96) Aegle occulted an 11.6 magnitude star. RECON team members Chris Patrick from Kingman Arizona, Steve Bock and John Heller from Indian Springs, and Tony George from Scottsdale recorded positive observations of the occultation.  Below is the light for this event from Kingman:

Below is a preliminary object profile for Aegle generated using data from Chris, Steve, Tony, and 5 additional IOTA observers.  You can view this and other 2015 IOTA results at Asteroid Occultation Results Page for North America.

20151230_AegleProfileUpdatedGreat job Chris, Steve, John, Tony, and other IOTA members!  Hope all enjoy the New Year Weekend!!!

Happy Winter Solstice!

We wanted to take this Winter Solstice opportunity to thank all of our teams for their exceptional involvement in RECON over the past year. It has been a truly exciting and productive year!

Looking forward to January, our next RECON campaign involving Centaur 03WL7 will occur on 20 January 2016 at 03:36 UTC. This event is earlier in the evening than our previous events, occurring on Tuesday, January 19 around 7:36PM Pacific / 8:36PM Mountain.

Wishing all a happy and health holiday season!!!  Marc, John, Jeralyn, and Ilianna

Daytime Occultation of Venus by the Moon!

This Monday morning, December 7, the waning crescent Moon will occult the planet Venus!  This event should be visible to the naked eye and will occur around 8:00 AM Pacific Time (7:53 AM in Seattle, 8:03 AM in Los Angeles).  Venus is visible to the naked eye during the daytime as long as you know where to look, and tomorrow the Moon will guide you to this point. Look for Venus just to the east of the moon about a half hour before the occultation, and then watch as the Moon approaches and blocks the planet from the west.

Final RECON Campaign of 2015

While skies are clear and a balmy 45-50 degrees down in Arizona and Southern California, our teams up in Washington and Oregon are in a race against the an advancing winter storm. The satellite image below taken at 04:15 UT sets the scene for tonight’s event.

For a more detailed site-by-site sky forecast, you can check out our Sky Conditions page. This page links into a service provided by Clear Sky Clock that gives a graphical representation of sky conditions based upon data from the National Weather Service. As you scroll down through the RECON sites, you can see sections of the network that are experiencing clouds and fog (represented by white) and other sites that are clear and cloud free (represented by blue).

Good luck to all of our telescope teams this evening!!!

 

RECON Double Header

Just four days after our occultation campaign involving 13WV107, our RECON teams will be out again this Friday evening / Saturday morning to record another Centaur. This time around, we are using astrometry data provided by collaborators in Brazil from the RIO Group to measure an object known as Bienor. The event will be pushing the limits of the RECON network because the target star is magnitude 16, just at the detection threshold for many of our cameras. Our team members will be paying close attention to obtaining the sharpest focus possible using the following Focusing Tips.

We just received an updated prediction map for this event from the RIO group, placing the shadow path over Northern California / Southern Oregon, although all telescope data is important, as always, for both capturing the main target and studying its neighborhood.

Updated path prediction as of December 3

During this event, we will also be joined by several other occultation astronomers from the North American International Occultation Timing Association (IOTA). The map below shows a portion of the telescope sites that will be participating in the event.

Unfortunately, sky conditions are not looking so good in Oregon and Washington due to a storm front moving in, but we will do our best regardless.  Thanks again to all of our RECON teams and our RIO and IOTA collaborators.
