UHF operation memorandam for March 3 BY S. Nozawa
(Using Netscape might be in trouble on this
page.)
Experiment name: arc1
(normal arc1 with the field-aligned-position:(184.0,77.1, 292.9)
We will make an optical
campaign using high resolution aurora cameras and 4-wavelength photometer with
EISCAT UHF radar. We strongly hope to use the ARC mode (at field-aligned
position) with the UHF radar. Sweden will contribute 8hrs to this campaign.
Also Norway will contribute 16hrs. NI(18), SW(8), NO(16)
elan files:
arc1-u.elan, arc1-k.elan, arc-s.élan (just use arc1 series)
directory:
/kst/exp/arc1-u (arc-k, arc1-s )
Pulse scheme: arc1
Start time: 19:00 UT on
March 3, 2003 (in fact, 18:55)
End time: 01:00 UT on
March 4, 2003
Participants: Satonori
Nozawa, Shuei Tomida, and Maarten Blixt
Before our experiment:
ALTA (Vikki Howells/Ivan Finch)
After our
experiment: Nothing
VHF is running
(ALTA:lt1nw-F2N) until 22:30 UT
Heating is running
until 22:12 UT

Cloudy.... Some activities are going on
though...
For 19:00-20:30, two groups have a
priority 1.
So, we decided to share the data with
running arc1-u.
19:00 START (enablerec;
kir enablerec; sod eneablerec)
The start time at
Tromsø is 18:55. Vikki changed the program of the UHF.
19:02 rtg at Kiruna on
the web is not started.
Tried “kir rtg”,
and it worked!
19:40 snowing?
20:45 1314 kW
22:04 -2 deg C.
21:34 1347 kW
22:28 The ionosphere is a bit active, but it is
snowing.
22:30 VHF ends
22:50 the ionosphere is being disturbed

UHF
This is the UHF part of the artificial
aurora and Langmuir turbulence experiment. The mode will probably be similar to
previous artificial aurora campaigns, namely tau2 on the UHF with a dedicated
Langmuir turbulence experiment (developed by Brett Isham) on the VHF and
simultaneous heating. This experiment needs good optical conditions, but low
geomagnetic activity. It can therefore be treated as an alternative to the
CP1-ARC experiment on days when both are scheduled, as conditions for these are
mutually exclusive. Because of the requirements on optical conditions, there
will almost inevitably be some degree of cancellation.
Heating
This is the heater part of the artificial
Langmuir turbulence and aurora experiment, see the notes for the UHF part. This
booking supersedes the Swedish "HFoptical" booking, which should be
deleted. Note that the Swedish
"arcHeating" booking still stands, as this is part of the alternative
experiment on natural auroras, which requires more active conditions.
VHF
This is the VHF part of the artificial
Langmuir turbulence and aurora experiment, see the notes for the UHF part.
Although a four-hour run has been requested, this will be followed by a
two-hour run requested by France (FR-AURORA), from 2030-2230, using the same
modulation to constitute a six-hour continuous VHF run in compliance with the
rules.
