22-May |
18:10 |
Arrived at National Guard Armory in Goodland, Kansas |
|
144 |
23-May | |
Setup interferometer platform |
|
146 |
25-May | |
Slow antenna and associated electronics were deployed. |
|
147 |
26-May |
1:39-2:50 |
Transferring data from Sun IPC to PC. A severe thunderstorm warning occurred prior to rearming system. |
| | |
Tied down platform & connected ground. Downloaded software needed for Sun Ultra/SBS915. |
| |
20:39-21:57 |
System was recording sferics at 23:39:10 until 21:57:??, but data had to be deleted to make room for later data. |
| |
23:01:00 |
Rain picking up |
| |
23:06:20 |
CG with net upward displacement of electric field |
| |
23:09:09 |
7 seconds to thunder (~2 km range) |
| |
23:11:06 |
Lightning at 1 km range |
| |
23:50 |
Light rain continuing to fall; contaminating slow antenna. |
|
148 |
27-May | |
Measured Lat/Lon in trailer at north window: 39 29' 10.3", 102 04' 49.5" |
|
149 |
28-May | |
Measured receiver PS voltage prior-to and after connecting to receivers: 12.67 V --> 12.00 V |
| | |
...Lower/upper PS voltages prior/after connection: Lower:(-12.01/+15.11)-->(-12.00/+15.03) Upper:(-14.10/+15.15)-->unchanged |

4:55:00 |
Attempted to acquire INTF data. Data deleted or problem on first attempt of STEPS 2000 to get INTF data? |
| |
5:22:33 |
CG to NNW |
| |
5:26:25 |
Nice SA field change. More such changes noted in subsequent seconds and minutes |
| |
5:42:01 |
Nice SA. |
| |
6:07:15 |
SA field change is very big. Estimate ~4 V max (2x full range). +CG? |
| |
6:11:13 |
A Slow Antenna field change is again offscale. |
| | |
According to daily planner notes, the interferometer data acquired today was bad (note low RF threshold) |
| | |
Measured Interferometer lat/lon/z as: 39 29' 11.0", 102 04' 49.9", 3917 ft? (lat/lon is accurate to 54 ft.) |
| | |
...and that of the slow antenna as: 39 29' 10.7", 102 04' 49.7" |
|

30-May |
1:57:14 |
Big positive bipolar with strong RF |
| |
1:59:47 |
+BP with multiple RF peaks |
| |
2:16 |
INTF display parameters listed as: DXS=214, DYS=62, Xshift=573, Yshift=-7 |
| |
? |
Test of receivers: Receivers 3-5 are ~dead! (1, 2, and 6 are OK). The problem was traced to damaged Local Oscillator connectors; primarily on the antenna end of the cables. The connectors were reseated. |
