> Sunspot numbers and solar flux were both lower this week. The
> average daily sunspot count dropped nearly 23 points, and average
> daily solar flux was down over 11 points. Solar flux is expected to
> drop down to 150 on Friday and Saturday, and then rise to near 185
> around June 20-25.
> 
> Last year during this same week the numbers were all lower. This
> week's sunspot average is over 66 points higher and the average
> solar flux is up by over 29 points compared to one year ago.
> 
> The average daily sunspot number for the month of May was 204.1, and
> the average solar flux was 178.4. The sunspot count for May was the
> highest monthly average for 2002. Average monthly sunspot numbers
> for January through May were 189, 194.5, 153.1, 194.9 and 204.1.
> Average solar flux for January through May was 227.3, 205, 179.5,
> 189.8 and 178.4. Cycle 23 is still holding up.
> 
> A coronal mass ejection on June 5 is expected to cause some
> geomagnetic upset on Friday. Currently the projected rise in

> Sunspot numbers for May 30 through June 5 were 190, 202, 192, 189,
> 208, 217 and 218, with a mean of 202.3. 10.7 cm flux was 180.1,
> 181.9, 178.8, 174.9, 170.4, 169.8, and 159, with a mean of 173.6.
> Estimated planetary A indices were 9, 6, 8, 16, 12, 17, and 10, with
> a mean of 11.1.
