Beginning shutdown procedures =====ToDo===== =====Notes===== * Is there a bad cloud cover protocol? Is it worth it to still take data? How badly does cloud cover coming in and out affect the data? * While bringing the ladder in it looks like the airspace around campus is being covered by super thick cumulus clouds while Baltimore looks pretty clear in the horizon. This is why the data wasn't working for us. When asking NOAA for weather data around arbutus/halethorpe, it tells automatically tells us data for Baltimore, since that's the closest forecast office to us - we don't have our own. Going forward. we learned skybot can be very wrong on whether we will be able to observe. It should be protocol for operators to go out and check the sky regularly if waiting for clouds to clear - we waited too long because we relied on the NOAA data. =====Weather===== | Time | Temp | Humidity | | 1800 | 46 | 49 | | 1900 | 44 | 51 | | 2000 | 44 | 53 | | 2100 | 42 | 57 | =====Data===== {{tag>[picsarr]}}
