Geophysical report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

B. Proton Events
None.
C. Geomagnetic Activity Summary
THE GEOMAGNETIC FIELD WAS AT
ACTIVE TO MINOR STORM LEVELS, WITH SOME MAJOR STORM PERIODS AT HIGH
LATITUDES. THE PERIOD FROM 0300-1500Z WAS PARTICULARLY DISTURBED AND
ATTAINED MAXIMUM FROM 09-12Z WITH AN ESTIMATED KP OF 6. THE
ACTIVITY WAS ASSOCIATED WITH A HIGH SPEED STREAM WITH VELOCITIES UP
TO 700 KM/S OBSERVED BY ACE.
D. Stratwarm
None.
E. Daily Indices: (real-time preliminary/estimated values)

F. Comments
THE FOLLOWING CHANGES WILL OCCUR ON MONDAY, 27 JULY: GOES-9 WILL BE TAKEN OUT OF OPERATIONAL STATUS GOES-8 WILL BECOME THE PRIMARY SATELLITE FOR SWO DATA AN PRODUCTS. GOES-10 WILL BE THE SECONDARY SATELLITE (THIS NOTICE SUPERCEDES THE EARLIER DECISION THAT HAD ASSIGNED GOES-10 AS PRIMARY)
All times in UTC
Current data suggests there is a slight possibility for aurora to appear at the following high latitude regions in the near future
Gillam, MB, Whitehorse, YT, Yellowknife, NTAnchorage, AK, Fairbanks, AK, Juneau, AK
