November 28th 2022, AA6DY, K9YO and KD9UQB

While we’re still following KD9UQB, over the Southern Ocean south of the Tasmanian Sea.

We expect in some areas of the world where our balloons may travel, we may not hear from them for days or even weeks, and then, they appear again.

Both Pico Balloon AA6DY and K9YO are Missing in Action, with an explanation.

AA6DY last reported on November 24th approaching West Africa. The NOAA Hysplit Model was showing AA6DY traveling across central Africa to Somalia on November 27th. Assuming that NOAA Trajectory was correct, I used that location and altitude and created another NOAA model for 84 hours which could explain why AA6DY still hasn’t been heard.

This is where AA6DY was expected by November 27th.

Below is the new NOAA Trajectory from November 27th thru December 1st

Which brings Pico Balloon AA6DY to just south of where we were, still off the coast of Somalia

Pico Balloon K9YO was last heard on Novmber 26th over Romania. Below was our Best Guess for Pico Balloon K9YO on Novmber 30th, usually a very quiet area for picking up signals.

As we wait to hear from our balloons, we’re still following KD9UQB on WSPR also tracking as W5KUB-115 on APRS and all our balloons together on APRS and our Locate and Track page with the new updated projected maps

We received an email from Hisami, 7L4IOU from Japan who was looking forward to picking up our Pico Balloon K9YO, WSPR signal approaching Japan. I hope this post helps you track our balloons. Thank you Hisami and all our followers around the world that help all our Pico Balloons find their way.

  1. Cary, you are the detective of WSRP signals – combining multiple Hysplit projections together. It looks like K9YO and AA6DY are both over quiet areas of the world, where there are few tracker stations. The effort of operators like Hisami, 7L4IOU, who seek out our balloons is extremely helpful. Not only to we get more tracking data, but their efforts reduce our anxiety when we can’t track a balloon for a few days.
    Thanks to everyone who tracks our balloons!
