Check out the map occultation prediction for Hi’iaka below. This event is picture-perfect for RECON!!! This event involves the largest known moon of Haumea, which is itself the third largest TNO after Pluto and Eris. This is a scientifically important opportunity for RECON to obtain the first occultation measurement of this satellites. Hi’iaka is actually larger than most of the objects we have attempted with RECON, estimated to be about 340 km across.
As with all campaigns this year, teams should follow CDC guidelines (including wearing masks and practicing physical distancing) to ensure the safety of all participants during the current COVID pandemic. Feel free to reach out to our email at email@example.com if there is anything we can do to help remotely. We appreciate you, RECON – stay safe!
With a highly ellipsoidal shape, Haumea measures roughly 2,000 × 1,500 × 1,000 km and is the third largest TNO after Pluto and Eris. This dwarf planet also has a ring and two smaller moons, Hi’iaka and Namaka. Predictions indicate that RECON is well situated to to measure Hi’iaka during this event with roughly a 70% chance of success if everyone participates. We currently do not have a RECON-generated event detail page for this event, but for useful information the event, visit: Haumea Details provided by Frédéric Vachier. Other important details for the observation are shown below.
We are not able to print a standard Event Detail Page for this event, but key observation details are provided below.
- Complete the RECON Campaign Signup Form for this event. Some participants have had trouble using Internet Explorer to sign up when there are more than one upcoming campaign. We recommend using an alternate internet browser. Submissions are updated hourly on our Signup Status Page.
- Keep power supply plugged in at all times except when in use. Make sure laptop is fully charged well in advance of the event.
- Print this page and the Event Detail Page (see link above) and practice on the target star field prior to the event.
Feel free to contact the RECON leadership team anytime by emailing firstname.lastname@example.org.
The of-date coordinates for the star are 14:24:53.2 +16:04:55 (for the RECON CPC1100’s). The J2000 position is 14:23:52.6 +16:10:40. The event mid-time is 06:35:30 UT for RECON. Take data from 06:30:30 to 06:40:30 UT. Use a sense-up of 32X for the MallinCAMs and a 500 ms exposure for the QHY174 cameras. Central events should last 7-8 seconds.

See our Full Campaign Observation Protocol Page for details on files to save. For teams with our new QHY cameras, you only need to save the event video. For teams still using our MallinCam setup, you should take the following four videos:
- Position Video
- Event Video
- Sky Field Video
- Dark Field Video
You should configure VirtualDub to save files sequentially by using “Set Capture File” to save as C:/Users/RECON/Data/YYYYMMDD/YYYYMMDD_01. You should record the filenames and information about each file using the RECON Observation Logsheet or a text file with the same information.

Regardless of whether your team was able to collect data, we need all teams to complete the RECON Campaign Observation Report Form within one week of the event. To view reports from teams from throughout the network, check out the Event Reporting Status Page.
If your team collected data, we also need you to save an electronic version of your log sheet and upload both your videos and observation log to SwRI in Boulder. For more information procedures for uploading data, visit Reporting Observations.
