Day 2.
Solar radiation's high - uv's 11+ if you can see, and for all I know the same if you can't. Star's mainsequence, G2IV maybe? Hard to get data, locallized EM disruptions seem to strike unpredictably. Last alert we got out of the environmental analyzer boilled down to "don't drink the water" - er. Pardon the pun.
Fortunately, the locals have developed a purification scheme involving fermentation and evaporation. Mixed with the local coffee analogue, quite palatable.
