- Unstable geomagnetic conditions finally started settling down this
- week. A very disruptive coronal hole in the Sun's Southern
- hemisphere was the cause of all the grief. Conditions may worsen
- again on the day this bulletin is released, and again around March 6
- when the recent disruptive region rotates back into view on the
- solar disk.
-
- Look for flux values to drop after this weekend, reaching a minimum
- around 85 on March 2 or 3.
-
- For the DX contest this weekend, look for a flux between 100 and
- 105, and A and K indices dropping after Friday.
-
- Sunspot Numbers from February 10 through 16 were 49, 49, 53, 72, 59,
- 59 and 71, with a mean of 58.9. 10.7 cm flux was 94.2, 93.1, 97.6,
- 97.8, 101, 103.8 and 104.7, with a mean of 98.9.

- The path projection for this weekend is from Orem, Utah to Bolivia.

- 80 meters should be open from 0100z to 1030z, with the best signals
- around 0300z. 40 meters should be open from 0030z to 1130z, with
- the best conditions from 0100z to 1000z. 30 meters should be good
- from 2330z to 1200z, with the best signals from 0130z to 1000z.
- 20 meters should be good after 2200z until 0230z on most days, until
- 0530z on some days, and on a few days until 0800z. The peak period
- for 20 meters should be from 0000z to 0230z. 17 meters should be
- open from 1430z to 0200z, with the best time around 2230z to 0130z.
- 15 meters should be open from 1530z to 0030z, with the best signals
- late in that period. 12 meters looks good from 1600z to 2300z. The
- best signals on 10 meters should be around 1800z, with a possibility
- of openings from 1700z to 2200z on most days. On some days 10
- meters could open as early as 1500z and close as late as 0130z.
