- SYNOPSIS OF ACTIVITY
- --------------------
-
- Solar activity became low due to several small C-class
- flares from Region 7742 (S08E29). This Region exhibited
- moderate growth but the weak delta configuration was not
- visible during the period. Big Bear observatory reports there
- is little shear in this region. Nearby Region 7743 (S11E41) was
- generally stable but some enhancements in Region 7742 coincided
- with point brightenings in Region 7743. A small region emerged
- near S16W04 and was numbered as Region 7744. (Note at press
- time: Region 7742 produced an M2 flare at 30/2124Z.)
-
- STD: The M2.5/1B flare noted above was associated with a 350
- sfu tenflare at 21:18 UTC that lasted 18 minutes. A strong
- Type II sweep was also associated with this event.
-
- Solar activity forecast: solar activity should continue
- generally low. Intermittent C-class flares are expected from
- Region 7742 with an isolated chance of a small M-class flare
- should growth continue and/or magnetic complexity reappear.
-
- The geomagnetic field was at mostly unsettled to active
- levels. Local nighttimes were the most disturbed periods.
- The greater than 2 MeV fluxes were at moderate levels
- for the first half of the period. High fluxes were
- observed during the latter half.
-
- Geophysical activity forecast: the geomagnetic field
- should be unsettled to active for the next three days.
- Isolated minor storm conditions are possible during local
- nighttime.

- B. High Latitudes
- Active 40/40/40
- Minor Storm 30/30/25
- Major-Severe Storm 15/15/10
-
- HF propagation conditions were near-normal over all
- regions. High and polar latitude paths may have experienced
- occassional minor signal degradation during the local night
- hours. A minor short wave fadeout was associated with todays
- M2.5/1B tenflare and may have affected middle or low-latitude
- sunlit paths on frequencies up to approximately 15 to 18 MHz.
- Similar near-normal conditions are expected to persist over the
- next 3 days, through 03 July inclusive. There is a chance
- Region 7742 could produce another minor M-class flare over the
- next 24 to 48 hours.

- NOTES:
- All times are in Universal Time (UT). Characters preceding begin, max,
- and end times are defined as: B = Before, U = Uncertain, A = After.
- All times associated with x-ray flares (ex. flares which produce
- associated x-ray bursts) refer to the begin, max, and end times of the
- x-rays. Flares which are not associated with x-ray signatures use the
- optical observations to determine the begin, max, and end times.
-
- Acronyms used to identify sweeps and optical phenomena include:
-
- II = Type II Sweep Frequency Event
- III = Type III Sweep
- IV = Type IV Sweep
- V = Type V Sweep
- Continuum = Continuum Radio Event
- Loop = Loop Prominence System,
- Spray = Limb Spray,
- Surge = Bright Limb Surge,
- EPL = Eruptive Prominence on the Limb.

- I'll be going to the Bahamas for my honeymoon in November.

- (1) Is my license good there to xmit?
- (2) Do *I* need to give my callsign differently
- (3) Well, gee, anything else I should know whilst travelling there???
