KST UHF operation memorandum for the December 13 experiment

(Using Netscape might be in trouble on this page.)

Experiment name: tau2pl (CP2)

 

This SP (CP2) is made to support a rocket launch from Andoya.@ All associations have contributed their SP times.

 

elan files:tau2pl-elan (just use taul2pl series)

Start time: 16:00 UT on December 13, 2004

End time: 04:00 UT on December 14, 2004

 

Participants: Satonori Nozawa, and Takuo Tsuda

 

Before our experiment: AAEV

After our experiment: nothing

December 13

@@@@@ Snowing.@ Temperature is 0 deg.

@@@@@ This is the 9th day for the Delta Campaign, and the last day.@

@@@@@ Because the sounding rocket was launched last night.

 

@@@@@ The waveguide was fixed.@ We gets nore more power: 1.9 MW

l AAEV: Aspect angle effects in the velocity of E-region coherent echoes

l A multi-instrument campaign involving EISCAT, CUTLASS (special mode), and

STARE. The requested time is overscheduled and cancellation will occur depending on geophysical conditions (moderate to disturbed). The AAEV campaign is coordinated with the CRASE experiment so that if one is cancelled then another one will be run or vice versa. Altogether (AAEV+CRASE) 46 hours are requested while only 34 will be used.@@@
