-
- 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

- 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.

- 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

-
- February 7
- Solar activity was very low.
- The geomagnetic field at Learmonth (WA) was storm levels during local
- night.

- .SK
- 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.
