The mated Russian-built Zarya (left) and U.S.-built Unity modules are backdropped against the blackness of space and Earth's horizon shortly after leaving Endeavour's cargo bay. The photo was taken with an electronic still camera at 21:20:21 GMT, Dec. 13.

Solar Activity
Solar activity was moderate this period with four R1 (Minor) events observed. New Region 3881 (S09E26) was numbered and Region 3871 (S09W62) reemerged with spots. Growth was noted in Regions 3871 and 3878 (N16E10) while the remaining regions were mostly stable. No Earth-directed CMEs were detected in available data.
Solar Wind
Solar wind parameters were slightly enhanced this period. Total field strength ranged 6-9 nT and the Bz component varied +8/-7 nT. Solar wind speeds gradually decreased from 500 km/s early in the period to around 400 km/s.
Energetic Particle
The greater than 10 MeV proton flux, which reached S1 (Minor) levels beginning at 26/1910 UTC and reached a peak of 364 pfu at 28/1350 UTC, decreased below the S1 level at 01/0735 UTC. The greater than 2 MeV electron flux was at normal and moderate levels. .Forecast... There is a chance for the greater than 10 MeV proton flux to reach S1 (Minor) levels over 02-04 Nov. The greater than 2 MeV electron flux is expected to be at normal to moderate levels through 04 Nov.
