Clouds of smoke billow out over the surrounding area as the uncrewed Skylab 1/Saturn V space vehicle launches from NASA’s Kennedy Space Center on May 14, 1973.

Solar Activity
Solar activity reached high levels this period. Region 3932 (S16E27, Ekc/beta-gamma) produced an impulsive M8.9 flare (R2-Moderate) at 23/1112 UTC; the largest event of the period. Development continued among the cluster of active regions in the SE quadrant. New Region 3936 (N15E48, Dko/beta) was split apart from Region 3934 (N13E35, Cao/beta), and new Region 3937 (S11E73, Axx/alpha) was numbered.
Solar Wind
Solar wind parameters were weakly enhanced this period. Total field reached a peak of 7 nT and Bz varied between +5/-7 nT. Solar wind speeds decreased from a peak of 700 km/s to around 550-600 km/s by the end of the period.
Energetic Particle
The greater than 10 MeV proton flux remained elevated above background but well below the S1 threshold, mostly due to activity that erupted on the far side of the Sun over 20 Dec. The greater than 2 MeV electron flux was at normal and moderate levels.
