Another week passed with no sunspots, and as of February 14 it has been over two weeks since any sunspots were observed, the last on January 30. February 7 through 13 saw average daily solar flux decline from 71.1 to 70.4, compared to the previous seven days. Geomagnetic indices were lower, with average daily planetary A index declining from 11.6 to 8.1, and average mid-latitude A index going from 8 to 6.1. Lower geomagnetic activity is generally good for HF propagation.
Predicted solar flux over the next 45 days is 70 on February 15-21, 72

Space Station Slow Scan TV Event Feb 15-17
ARISS is planning another of their popular Slow Scan Television (SSTV) experiment events from the International Space Station on February 15-17
Transmissions on 145.800 MHz FM are scheduled to begin Friday, Feb. 15 at 08:45 UT and run through Sunday, Feb. 17 at 17:25 UT.
SSTV operations is a process by which images are sent from the International Space Station (ISS) via ham radio and received by ham operators, shortwave listeners and other radio enthusiasts on Earth, similar to pictures shared on cell phones using Twitter or Instagram.
