Remarks
Second night of the expedition. After midnight it cleared up and thunderstorms left the Provence. A moderate wind called the "mistral" brought us crystal clear skies. Pretty nice night, rising Perseid activity. But at first sight nothing special happened (still have to calculate the ZHR's)
In progress ; more expedition nights (12-13 ; the main maximum, 13-14 and 14-15 August). But now time for a little beer...
Kind regards,
