TRICE rocket campaign 2007

CUTLASS operations plan

CUTLASS operations schedule

EISCAT operations schedule

Launch window: 07-11 UT, Dec 4-16, 2007

rocket trajectory

Apogee of both rockets is ~ on the ESR field line.  This is magnetically conjugate to (roughly) Finland beam 9, range gate 33 (1890 km), Iceland beam 6 range gate 40 (2115 km) for the scan mode used in the campaign.  Gates marked every 10th gate in the trajectory plots in the link above.

Summary of launch timeline
T - 03:00 h contact air traffic control etc.
T - 01:30 h contact EISCAT and SuperDARN
T - 00:40 h hold for science
T - 00:06 h hold for science
T - 00:03 h hold for science

Rocketrange webpage:

A lag to first range of 900 km, and a range gate size of 30 km offers good coverage around the trajectory from both the Finland and Iceland radars. We will run a 3 s dwell, with full 16 beam coverage on channel A of both radars (a scan resolution of 48 s), and a reduced scan of beams 5-11 on Finland and 3-9 on Iceland (21 s scan resolution). 

Frequency management will be done manually from Leicester during the launch window.

The sort of thing we'd like to see is shown here, using old data from earlier in the year.  Note the ESR is at range gate 38 in this standard scan, not gate 33 as in the rocket scan mode used for TRICE.
EISCAT mainland modes:

UHF (Norwegian time) and VHF (French time) will be combined, both at low elevation looking
north over Svalbard for convection experiment.

Campaign diary

  Launch scrubbed due to late arrival of equipment.  Practicing at rocket range and CUTLASS.
Some nice auroral observations, cutlass backscatter and features in the ESR data, which had the 32 m dish pointing north at low elevation, where the action was.  Conditions mostly IMF northward with sunward flow bursts seen by CUTLASS, and mostly a little too far north.  So some nice ground data collected, although not quite what TRICE was looking for.  Receiver and other problems up on Svalbard prevented a launch until too late in the window.
  Again some decent data in optics and radar, but mostly north of Svalbard, and the IMF northward or close to zero.  Mostly too windy at Andoya for launch.
  Decent ground-based data.  Even a brief interval of IMF Bz south, which produced classical reconnection signatures in CUTLASS.  Too brief and too high latitudes for TRICE, however, which had high wind issues again.
Both yesterday and today we were out all day for winds. It is the same situation we have been having with tailwind that was too strong and would have required an elevation angle setting below what is allowed for our vehicles. The science was also not very interesting on either day. It was almost exclusively northward or at zero IMF Bz with very weak PMAF activity that was north of Svalbard.
Tomorrow the winds are supposed to shift and solar rotation should start to bring us a more active solar wind (based
on the last Carrington cycle), so we are hopeful our conditions will improve.
No launch today. However, the winds have improved and we were in for launch for most of today's window.
We had some activity to the north of our trjectory, but the IMF did not cooprate and we never got Bz negative during the window. Solar wind speed was up and should continue to increase over the next few days, so we remain hopeful that we will launch very soon.
The TRICE rockets launched today at 0900:00 UT and 0902:00 UT. We had excellent science conditions for measurements in the Earth's cusp with a southward turning of the IMF a few minutes before launch that appears to have then turned northward for  the last
piece of the flight. Both payload appear to have worked well and both trajectories were within about
2 sigma of expected performance. We have good data from the CUTLASS radar, all-sky cameras in Ny Alesund, and EISCAT.
