1. MISSION OVERVIEW

The scope system was set up in record time for this mission 87, 7 minutes. Imaging began at 8 PM.  Due to the Coronal Mass Ejection of last week, radio communications were the worst ever, even causing aircraft flights to be cancelled. There was no WWV time dub although we have a time fix from a previous session and the Quad display which was a 42 second lead on the actual WWV time signal. Imaging was good once it was dark enough but the session was cut short when the target entered an obstruction to the south. The mission was worth it and lasted about 45 minutes.

3. DETAILED REPORT

 

 

 

02H50M59S Q start
02H56M35S Cam 4 on target
No WWV


02H51M06S Q-Select
02H51M24S Cam 4 online
04H19M00S Check for anom target observed / Jet found
02H59M??S Late start on DVR2 b 8 mins
Carrier feq and beep but WWV not readable


Findercam not working

CabCam good


DVR2 good, some artifacts


Quad time / DVR coorelation plotted
03H06M12S Q is 02:59:25 elapsed (moon occulted by obstruction at 06:47). There’s a 42-second difference between the Quad Time and WWV with QT leading.

 

New Procedures: (Paste this data into TJR)

)1) #11 Install #11 Yellow Wwratten filter on SSI cam next mission
2) Create better antenna for the Sennheiser Wireless receiver so LIMO door won't have to be open.

3) 15' USB cable ordered to replace 10' - get cam system farther from LIMO

4) Add focus monitor to yoke, SSI camera set all the way in, then foccussed.
5) Replace short 2-wire RCA cable with 3-wire RCA so focus cam can be plugged into the AV panel.

6) Problem with DVR1 getting into L2. Input command causes DVD to eject on both DVRs. DVR1 input mode was set at L1 which is the default setting. DVR2 was left at L2 but should be check prior to missions.

7 Plexiglass roof panel needs to be installed over roof vent to keep temp down.

 

CONCLUSIONS

Good targets and very good imaging, but no anomalies. SKYCAM needs more work (night vsion cam?).
