Original Announcement:
EOSS-218 Postponement: Unfortunately, EOSS-218 will need to be postponed until January with the final date TBD. Our latest predictions continue to indicate that the balloons will be almost a hundred miles down range, with up to 20 miles of separation. Additionally, communication in the landing area will be challenging. In order to avoid spreading resources too thin, we have decided to postpone EOSS-218 until January. We don't like to make this decision at this late point, but we feel this is the best action to ensure that we do not place customers and EOSS personnel in a situation that could compromise safety or recovery of the payloads.Note: The pre-flight net will be at 7:00 pm on the RMRL 449.450 MHz repeater. This is a different time and frequency. See below for further details.EOSS-217 Will be a pre-dawn launch to a accomodate a NOAA experiment with a water vapor sensor. A Certification of Authorization from the FAA has been issued to allow flight prior to sunrise. A five-mile visibility strobe will be included on the flight string in addition to the usual EOSS beacons. The COA is available for viewing at: http://www.eoss.org/file/302EOSS-218 Will be a 2000g balloon flying an experiment investigating HDTV ground based signal strength for graduate student research from the University of Colorado. Additionally, it will contain an experiment from the students of Montclair School of Academics and EnrichmentFlight predictions can be reviewed at http://www-frd.fsl.noaa.gov/mab/sdb/predict_0.htm

TR Breakfast:
Note the pre-flight net will be conducted at 7:00. Stay tuned for dinner arrangements at 5:30 in Ft. Morgan.
Flight Preps are starting at 2:00 a.m., launch at 4:00 a.m.. Watch this space for further information.
Hello Trackers (grid stays the same)
It looks like tomorrow's flight will be quite an adventure. Here are some updates regarding procedures and issues.
Dinner will be at Ft. Morgan, Cables Pub and Grill, 431 Main Street, 970-867-6144. We have 5:30 reservations under "Marty". American food. Be sure to gas up in Ft. Morgan as we have a long trip ahead of us. Many folks are staying at the Hampton Inn and others are staying at the Rodeway Inn. There will be a preflight net on the RMRL Repeater, 449.450 at 7:00 to get most of us to bed at a reasonable time. Note this is NOT the 147.225 machine!
There is no cell coverage and no repeater coverage in eastern Colorado or Western Nebraska. Most of our work will be done on 446.100 simplex. We will investigate using the Holyoke Colorado repeater (146.955 - ) in the morning. We will travel in groups to maintain radio contact with members of the group. I have a pretty good list of cell numbers for the members of each team.
Team 217: We will encourage all 217 team trackers to leave for the recovery site as soon as 217 is launched. Alpha, Bravo and Echo will leave before 217 launch to get a head start on a 2.4 hour travel time to Nebraska. We will lose the 449.450 repeater shortly after leaving Ft. Morgan, but we may be lucky for a while.
We must stay in a group and make group decisions as to how we will progress. Please maintain constant communications with team members. We will head for Imperial Nebraska at the Imperial Municipal Airport if we get there before landing. The objective is for all members of the team to stay in constant APRS contact with EOSS 217 and with each other. Ultimately we will alter our Imperial plans and head for the landing site. Plan to travel to Sterling and head east on Highway 6. The customer is Sean and Lars who will travel to the recovery site.
The second team will leave the launch site after the launch and stay in its own group. Stay in touch with each other.
That is all I have for now. Watch the Web pages and you email for possible changing information.
