To: ham-space@ucsd.edu
If you call West Marine at any of their Seattlelocations you can
probably get one of two "brand" name handheld gps, multi-channel
units for $449.00. These give location, elevation, direction and speed
of travel, and bounce quite well. I really don't think you
will do much better than that, since the OEM units are priced to
discourage amateur players like us. They offer less, need more external
support (antennas, software and a laptop or better), but cost more.
Good luck / Mark

SB SAREX @ AMSAT $STS-60.009
SAREX Keps for Feb. 8
The official SAREX element set for today will be GSFC-009. This element
set was generated by Ron Parise, WA4SIR of the Goddard Space Flight
Center. Gil Carman, WA5NOM reports that the predictions using GSFC-009
differed from GSFC-005 by approximately 11 seconds.

Does anyone happen to have the actual unified S-Band downlink or TDRS freqs
from the Shuttle?

To: ham-space@ucsd.edu
The most current orbital elements from the NORAD two-line element sets are
carried on the Celestial BBS, (513) *253-9767*, and are updated daily (when
possible). Documentation and tracking software are also available on this
system. As a service to the satellite user community, the most current
elements for the current shuttle mission are provided below. The Celestial
BBS may be accessed 24 hours/day at 300, 1200, 2400, 4800, or 9600 bps using
8 data bits, 1 stop bit, no parity.
Element sets (also updated daily), shuttle elements, and some documentation
and software are also available via anonymous ftp from archive.afit.af.mil
(129.92.1.66) in the directory pub/space.

SUMMARY OF ACTIVITY
February 4
Solar activity was very low.
The geomagnetic field at Learmonth (WA) was mostly quiet with
unsettled to active conditions 12-21UT.
Ionospheric F2 critical frequencies at Sydney were near predicted
monthly values to 15% enhanced during local night.
February 5
Solar activity was very low.
The geomagnetic field at Learmonth (WA) was mostly quiet to unsettled.
Ionospheric F2 critical frequencies at Sydney were near predicted
monthly values to 30% enhanced during local night.
February 6
Solar activity was very low.
The geomagnetic field at Learmonth (WA) was at storm levels.
Ionospheric F2 critical frequencies at Sydney were about 10-20% below
predicted monthly values
February 7

February 8
Solar activity was very low.
The geomagnetic field at Learmonth (WA) was at active to minor storm
levels.
Ionospheric F2 critical frequencies at Sydney were 10 to 30% below
predicted monthly values.
February 9
Solar activity was very low.
The geomagnetic field at Learmonth (WA) was at active to minor storm
levels observed during local night.
Ionospheric F2 critical frequencies at Sydney were depressed
20-30% 00-02UT then recovering to near predicted values.
February 10
Solar activity was low.
The geomagnetic field at Learmonth (WA) was at active to minor
storm levels during local night.
Ionospheric F2 critical frequencies at Sydney were about 15% below
predicted monthly values.
Comment:
Strong magnetic storm activity was observed during Feb 6-8. This
activity arrived a day earlier than expected and was stronger
than expected. Storm was due to a coronal hole.
FORECAST FOR THE NEXT WEEK (11 - 17 FEBRUARY)
SOLAR: low to moderate
GEOMAGNETIC: active due to coronal hole.
IONOSPHERIC: degraded HF communications expected all week.
MUFs are expected to be 10-15% depressed on IPS predicted
monthly values.
