1A. SOLAR SUMMARY
Activity 19 Nov:  Low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 19 Nov: 134/88

1B. SOLAR FORECAST

COMMENT: A CME associated with a filament lift off was observed 
in LASCO/SDO/STEREO images 18 Nov/~2030 UT originating from the 
south-east limb; it is not expected to be geo-effective. A few 
C-class flares, the largest a C7.0 at 0228 UT from growing beta-gamma 
region 1618 (N07 E28). New, simple region located at S13 E73. 
ACE data show the solar wind was mostly undisturbed with speed 
ranging between 350 and 450 km/s. Region 1618 may produce M-class 
flares. The solar wind is expected to be mostly undisturbed over 
the forecast period.

Observed Regional daily pc3 Indices 19 Nov : 
      Darwin               0   (Quiet)

Pc3 pulsations are high frequency (10-45 second period) variations 
of the Earths magnetic field. Daily pc3-indices are the daily sum 
of 20 minute pc3-indices for that station and have been shown to be
well correlated with rejection of high resolution aeromagnetic
survey flight-line data. 

NOTE: Indices may have been generated from data obtained in 
cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and International Center for Space Weather 
Science and Education, Japan.
