4 September Low cloud and launch failures

winds 010/10, very low cloud and drizzle to start. Clearing early pm.

Perfect conditions to practice ultra low and low launch failures. Later practising signal too fast and abandoning the launch.

In between the good spells, classroom work included unravelling DALRs and SALRs and how we determine thermal heights and cloudbase.

The weather Wednesday will be much improved, but still not like our glorious summer.
