**Introduction**
After seeing nice Keograms
on SpaceWeather I wanted to make a Windows ready software capable of making
those images.
But after seeing a few movies of auroras used for this, I knew that I had
to go further!
This is why, in about one hundred hours, I created Keogram Master which
excels in making bi-directional Keograms showing the events with more fidelity!
I am waiting for your feedback on sweiller[at]free[dot]fr .
