In honor of the current heat wave I am providing some heat-related weather terms (source: NOAA glossary).
- Cooling Degree Days
- (Abbrev. CDD) - A form of Degree Day used to estimate energy requirements for air conditioning or refrigeration. Typically, cooling degree days are calculated as how much warmer the mean temperature at a location is than 65°F on a given day. For example, if a location experiences a mean temperature of 75°F on a certain day, there were 10 CDD (Cooling Degree Days) that day because 75 - 65 = 10.
- Excessive Heat
- Excessive heat occurs from a combination of high temperatures (significantly above normal) and high humidities. At certain levels, the human body cannot maintain proper internal temperatures and may experience heat stroke. The "Heat Index" is a measure of the effect of the combined elements on the body.
- Excessive Heat Outlook
- This CPC product, a combination of temperature and humidity over a certain number of days, is designed to provide an indication of areas of the country where people and animals may need to take precautions against the heat during May to November.
- Excessive Heat Warning
- Issued within 12 hours of the onset of the following criteria: heat index of at least 105°F for more than 3 hours per day for 2 consecutive days, or heat index more than 115°F for any period of time.
- Excessive Heat Watch
- Issued by the National Weather Service when heat indices in excess of 105ºF (41ºC) during the day combined with nighttime low temperatures of 80ºF (27ºC) or higher are forecast to occur for two consecutive days.
- Heat Advisoty
- Issued within 12 hours of the onset of the following conditions: heat index of at least 105°F but less than 115°F for less than 3 hours per day, or nighttime lows above 80°F for 2 consecutive days.
- Heat Exhaustion
- A mild form of heat stroke, characterized by faintness, dizziness, and heavy sweating.
- Heat Index
- The Heat Index (HI) or the "Apparent Temperature" is an accurate measure of how hot it really feels when the Relative Humidity (RH) is added to the actual air temperature.
The formula for calculating the Heat Index is
HI = -42.379 + 2.04901523T + 10.14333127R - 0.22475541TR - 6.83783x10-3T2 - 5.481717x10-2R2 + 1.22874x10-3T2R + 8.5282x10-4TR2 - 1.99x10-6T2R2
where
T = ambient dry bulb temperature degrees Fahrenheit
R = relative humidity
Accurate to ±1.3° F
- Heat Stroke
- A condition resulting from excessive exposure to intense heat, characterized by high fever, collapse, and sometimes convulsions or coma.
- Heat Wave
- A period of abnormally and uncomfortably hot and unusually humid weather. Typically a heat wave lasts two or more days.

- Palus somni is a little subdued. Picard (22 km) is visible in the otherwise featureless Mare Crisium.
- I can see Isidorus (42 km) and Capella (90 km) at the tip of Mare Nectaris but can’t find Rimae Gutenberg
- Grego says I should be seeing color variations in Mare Serenitatis but all I can find is the Serpentine Ridge, primarily Dorsa Smirnov, which seems to have a brighter stripe down through it’s middle. There is more relief evident around the southern and eastern interior edges of the mare than in the north and west.

| Comments | Saturn is forming a right triangle with Regulus and Algieba.
I can’t resolve the rings tonight no matter what I do with the scope.

I tried star hopping to some clusters up around Arcturus and down near Spica but it wasn’t happening.
