All solar indicators rose this week. New sunspots emerged, and the
average daily sunspot number for this week rose over 43 points.
Average solar flux was up 32 points. 289 was the sunspot number on
Sunday, the highest since April 1, when it was 320. Around the end
of March there was a huge increase in sunspots, which will probably
move the smoothed value for the peak of Cycle 23 to a later season
than earlier assumed. Over the past two weeks we have witnessed
another large run up in activity, although not quite as sharp but
perhaps a little more sustained than the increase at the end of
March.

A strong interplanetary shock wave struck earth on Monday, beginning
its journey last Friday from a coronal mass ejection. The ejection
was not aimed toward earth, but as it expanded through the gaseous
interplanetary medium it created a shock wave that affected earth's
magnetosphere. The result was a planetary A index on Monday of 34.

Solar flux for Friday through Monday is expected to be 205, 205, 200
and 195. Geomagnetic conditions should be fairly stable, with a
predicted planetary A index of 10, 10, 10 and 12 for the same days.

Interest in conditions for Field Day this weekend is running high.
We have just passed the summer solstice, and from now until the end
of the year the days get shorter. Several months from now we will be
back to fall conditions, with better 12 and 10 meter openings,
especially in the higher latitudes.

But this weekend Field Day operators will not be concentrating on
working DX, because the focus of the operating event is on making
lots of contacts while operating in the field. We will present some
path projections, but the targets will all be domestic. For those
interested in racking up points, remember that the emphasis is on
the number of contacts, not number of states, sections or countries
worked, since those don't count for multipliers.

Here are the path projections, based on an average solar flux of
203. Since Alaska and Hawaii are often neglected in this bulletin,
we will begin with them. The lists will get shorter for subsequent
target areas, because the same paths have already been shown in a
previous target. Remember the paths work both ways. If you want to
do your own projections, download W6ELprop from
