  68. SYNOPSIS OF ACTIVITY
  69. --------------------
  70.  
  71.              Solar activity became low. Region 7648 (N07W79) produced
  72.        a C1/SF at 0916Z. Another C1 occurred at 1612Z and was
  73.        coincident in time with the beginning of an active surge region
  74.        near NE05. The delta configuration in Region 7650 (N05W67)
  75.        appears to have faded.
  76.  
  77.             Solar activity forecast:  solar activity should continue
  78.        generally low with the emphasis shifting from the west limb
  79.        to the new region at the east limb. Due to the lack of
  80.        frequent burst activity, it is likely old Region 7640 will
  81.        not be as active this rotation as it was last rotation.
  82.  
  83.             The geomagnetic field was generally unsettled to active.
  84.        Intermittent minor to major storm periods were observed at
  85.        some high latitude sites.
  86.  
  87.             Geophysical activity forecast:  the geomagnetic field
  88.        should continue unsettled to slightly active for 15-16 Jan.
  89.        High latitudes should expect isolated storm conditions.
  90.        Mostly unsettled levels are predicted for 17 Jan.

  111.             HF propagation conditions were near-normal from the middle
  112.        to equatorial paths.  Occasional minor signal degradation
  113.        persisted on higher latitude paths, particularly night-sector
  114.        transauroral circuits.  Similar, if not gradually improving,
  115.        conditions are expected over the next 72 hours.

  289. NOTES:
  290.        Predicted geomagnetic activity is based heavily on recurrent
  291. phenomena. Transient energetic solar events cannot be predicted reliably over
  292. periods in excess of several days.  Hence, there may be some deviations from
  293. the predictions due to the unpredictable transient solar component.

  548. NOTES:
  549.       These VHF DX prediction charts are defined for the 30 MHz to 220 MHz
  550. bands.  They are based primarily on phenomena which can affect VHF DX
  551. propagation globally.  They should be used only as a guide to potential
  552. DX conditions on VHF bands.  Latitudinal boundaries are the same as those for
  553. the HF predictions charts.
