Is the real Y2K problem just starting? NASA scientists say not to worry. The solar cycle appears to be on schedule for a peak in mid-2000, but this year's Solar Max appears to be slightly smaller than peaks registered in 1978 and 1989. Check out this story for predictions and for a summary of recent solar activity.
