Flight #23 - 2014a

 

This will be a joint flight in conjunction with Bill Brown, WB8ELK.  With a limited chase team, I've decided to partner up with Bill and hitch a ride on his flight string.

 

pt2014-earth-view-smallI do hope to get the new Arduino tracker running before the June 14th launch but there is still a pretty significant bug in the code that I can't find.  If that doesn't get fixed, then I'll fly the older Arduino Track controller again.  Update, I found the bug with the controller (actually wound up being in the tracking software and not the hardware at all.  Initial testing has gone very well with the new controller and I plan on flying that on the 14th.

June 11

The hook back to the west is still gone, but winds are still light to moderate throughout the flight.  Surface weather continues to look good although will be a bit breezy.

 

Unless there is a drastic change in weather by tomorrow, plan on a Hutchinson launch.

June 10

Surface weather is still looking favorable for Saturday morning with temperatures around 70F.  Tracks have mostely stablized to an east-northeast at ~30 miles, depending on the flight parameters.  The only difference I'm seeing today is a lack of a hook back to the west at upper levels. 

 

Central Kansas has had a lot of rain over the past two weeks, so expect field conditions to be damp and muddy.

June 9

Same eastern track.  The weather forecasts are showing minimal chance of rain over the Friday-Saturday period, and surface winds in the 10-20mph range.  Mid-day temperatures are forecast to be in the upper 80'sF. 

 

20140609

 

June 8

The winds are picking up just a little bit, but still tracking east.

 

20140608

 

June 7

Continuing the same pattern of an easterly track.

 

20140607

 

June 6

We're getting close enough for me to flip over to the GFS192 modeling.  The track is very similar to the June 4th prediction, only slightly shorter.  A Hutch launch is looking promising.

 

20140606

 

 

June 4

The forecasts continue to be all over the board.  Today it is pushing the flight east-southeast towards (but not as far as) Newton.

 

20140604

 

June 2

Predictions have shifted by almost 180 degrees over the past two days.  Yesterday's prediction which I didn't save, pushed the flight southeast towards Wichita/Eldorado.

20140602

May 30

Initial predictions are encouraging for a launch from Hutchinson.  A water landing in Cheney would be a concern, but otherwise looks good.
