NOTE: The Effective Sunspot Number for 23 DEC 93 is not available. The Full Kp Indices for 23 DEC 93 are: 2- 3- 1+ 3- 3- 2+ 2- 3+ SYNOPSIS OF ACTIVITY -------------------- Solar activity was moderate. Region 7640 (N08E21) produced two M1/1N flares maxing at 1507Z and 1815Z. No radio activity was reported with these two flares. Numerous C-class flaring has also occurred in this region over the past 24 hours. White light observations indicate 7640 has nearly doubled in spot number and has grown significantly in area with rapid penumbra development throughout the region. Two new Regions were numbered overnight -- Rgn 7642 (N10W20) and Rgn 7643 (S16E69). All other regions were stable. One other item of note to pass on: just minutes ago, Santa Claus was positively identified on radar leaving the polar cap and passing through the auroral oval. Any minor disturbances in ionospheric signatures should be attributed to this seasonal phenomenon. Solar activity forecast: solar activity is expected to be moderate. Continued development in Region 7640 should produce more M-class activity with a slight chance of X-class activity. STD: Big Bear reported new positive polarity flux emerging just slightly southwest of the main negative polarity leader flux. If this feature persists, it could result in additional C and M class flare activity and may even possibly provide a mechanism for a stronger event. This region now encompasses an impressive 73 spots and is bright in x-rays, as illistrated in the appended full-disk Yohkoh x-ray image. A small and potentially mildly geoeffective southern hemisphere coronal hole crossed the central meridian over the last 24 to 36 hours. Although it is still difficult to discern, there appears to be a moderately large coronal hole to the east and north of Region 7640, just now rotating into view. The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Geophysical activity forecast: the geomagnetic field is expected to be mostly quiet.

Middle Latitudes Active 10/10/15 Minor Storm 05/05/05 Major-Severe Storm 01/01/01 B. High Latitudes Active 10/10/15 Minor Storm 05/05/10 Major-Severe Storm 01/01/01 STD: HF propagation conditions have not changed over the last 24 hours. High and polar latitude regions continued to observe occasional periods of minor signal degradation (poor propagation). Middle and low latitudes experienced near-normal propagation. There was a confirmed minor SWF on frequencies as high as approximately 10 to 12 MHz at about 18:15 UTC. No changes are expected over the next 72 hours. SWF activity will remain quite possible over daylit paths throughout the next several days.
