We have mentioned that depending on where we are in the world, we may not always hear from our balloons. K9YO went silent for a day and just reported a 2nd packet at Grid LN62IT on October 31st at 06:00 UTC at 780 meters (The second packet only gives us a partial altitude)
Because the 2nd packet is only a hint of being our balloon, we need to go back and look at the projected path and verify if indeed this is our balloon.
K9YO last reported at Grid JO27sk on October 29th at 10:40 UTC
The NOAA Hysplit model has K9YO going over the Caspian Sea on October 31st
K9YO at Grid LN62IT on October 31st at 06:00 UTC, Altitude 12,780 meters, 41,918 feet Just east of the Caspian Sea, Kazakhstan
AA6DY was last reported on October 29th at Grid HL90ii.
The NOAA Hysplit Model below for AA6DY from October 29th thru November 2nd 2022
AA6DY did receive some 1st packets on October 30th between Grid IK70 and IJ89.
While writing this post, we just received from AA6DY, Grid JK57MJ at 13:44 UTC as the NOAA Hysplit Model has projected. (two large red triangles and 2 red small triangles representing October 31st 12:00 UTC AA6DY is flying at an altitude of 14,240 meters, 46.707 feet.
We are still only receiving intermittent 1st or 2nd packets for both our balloons, our altitudes have remained fairly constant. As our balloons continue to move east, we hope that our regular followers will find our locations and report.
We’re showing with the NOAA Hysplit Trajectory models that K9YO will be over the North Pacific Ocean on November 3rd and AA6DY will be near Japan on November 4th. These models are now updated on our Locate and Track page. The Ventusky wind direction and speed are also updated for October 31st at 15:00 UTC
I noticed that the NOAA models on our website have a limited life span,of a day or two, after that, you’ll see a note page not found. We create these models based on data received from the Gridmapper for Longitude and Lattitude, and altitude from WSPR Net and WSPR Rocks.
We use this link from NOAA Balloon Optimization Calculation
We hope to update the Sondehub and APRS links once we start receving more spotters.
