I would also recommend Weather Underground. If you use it however, be aware it doesn't always have this info (sky condition or sky cover). For example, see the same day's data (12-25-10) for Norcross GA, where my group in GA has had a number of sightings from in the last 2 years: http://tinyurl.com/22p4sv3 Scrolling down to the tabulated data, you'll see no entries under "clouds." When I was looking into Norcross sightings, I used this station becaue it was closest to the actual sighting location. For one of them, the presence or absence of fog was an issue; so I wanted the station closest to the sighting, Not the closest airport to the sighting. This is a big advantage for Weather Underground - they have stations (some automated, just devices are there) all over the place. In my case, they had an automated station just 1000 feet north of the location in question. Weather Underground calls these "personal weather stations" (PWS) and their ID for the one linked above, is KGANORCR9. But - as I mentioned, no sky condition data. If that's the case for your sighting, you'll need to get that info from the nearest place where it is recorded. So far as I know, it is only recorded at airports (maybe elsewhere too, but airports for sure). There, the data are recorded as part of the standard weather-observations data set called a "METAR." There is an online repository of archived METARs and other met reports, at: http://www.ogimet.com click "English version" at top left. Near the top, you'll see "METAR and TAF queries." Click there, then all you need do is enter the airport's ICAO code (a 4-digit code, such as "KPDK"), and the Universal Time (aka Zulu Time) period that encompasses the sighting time (you must convert local sighting time to Zulu time, based on time zone). OGIMET does have a ICAO code-finder search-box there, too, although you will need the airport's common name. If the airport does happen to be your closest station, Weather Underground does give the METARs for the archived days, so in that case it's easy and you can skip OGIMET or similar archives. They (Underground) have a handy "METAR FAQ" also, so you might want to check that out, since the METARs describe cloud cover as BKN, OVC etc. (broken, overcast), which have defined meanings in eighths of sky covered. Hope this is useful to you. Ralph Howard State Director & FI, MUFON-Georgia rhjr.nul www.mufonga.org Listen to 'Strange Days...
