Since our interest is astronomy, our day ends in the morning. The day long chart will end at 8AM on the day entered, displaying the previous 32 hours. You may also enter the Julian date of observations instead. In this case, one would add 24 in front of the five digit image file name. The archives are updated at 17:30 each day, so a query for the current day should be done on the regular weather page. Weather Data started being collected on Feb 08, 2004
