Overview of useful spectral regions for Venus: An update to encourage observations complementary to the Akatsuki mission

New tables to observe the planet Venus are presented with detailed information about the main spectral regions from 100 nm to 1 mm. The information hereby is updated thanks to the Venus Express legacy and recent ground-based observations, and we hope it can constitute a helpful tool for professional and amateur observers willing to support and coordinate with the JAXA's Venus Climate Orbiter/Akatsuki mission.
