Forecast: Solar activity is expected to remain at very low levels on 16-18 Feb.

Energetic Particles

24 hr Summary: The greater than 2 MeV electron flux reached moderate levels and the greater than 10 MeV proton flux remained at background levels.

Forecast: The greater than 2 MeV electron flux is expected to be at normal to moderate levels through 17 Feb. The greater than 10 MeV proton flux is expected to remain at background levels.

Solar Wind

24 hr Summary: The solar wind parameters were slightly enhanced this period. Total field was at 7-10 nT and the Bz component underwent sustained, southward deflections of -6 to -8 nT from ~16/0157-0830 UTC. Wind speeds saw a small uptick during the aforementioned time from, climbing from 330 km/s to ~370 km/s. Phi oscillated between positive and negative solar sectors.

Forecast: Slight enhancements to the solar wind environment are expected to continue over the course of 16 Feb. A return to nominal conditions is anticipated for 17-18 Feb.

Geospace

24 hr Summary: The geomagnetic field was quiet to active.
