For the record: this is two and three of four test forecasts that I made, in order to make sure I could even contribute to the group. I screenshot it on Snapchat.
I had Japan on alert for 48 hours (4.9 struck within alert window) and Russia on alert for 24 hours. (I made an error in the timeframe projection and there was a quake in the exact same area as my alert star soon after)
Following photo shows date stamp of created alert map, along with set alert time window.
