> Sunspots continue to be scarce, although numbers have risen the past
> couple of days. Several days this week had 0 spots (March 25-27),
> but then they rose over the next few days to 11, 31 and 35.
> Geomagnetic conditions have been nice and stable, and should
> continue until April 6.

> Even last weekend when there were no sunspots, 10 meters was active
> during the WPX contest. Bill Hohnstein, K0HA of Seward, Nebraska
> said that A35RK in Tonga worked EA8TX in the Canary Islands, a path
> of nearly 11,000 miles. This was on March 26 around 2153z. Around
> that time Bill also worked both of these stations. 
> 
> He worked many strong Central and South American stations on 10
> meters, as well as ZD8Z on Ascension Island and AH6RF in Hawaii.
> Bill also copied the ZL2MHF beacon, which runs 10 watts to a
> vertical antenna, and his longest path was his QSO with ZL1ANJ,
> 7,709 miles, at 1957z on March 26.
