[This is the first entry in my online observing blog. The line above is the same as I use in my paper log, and gives the basics of the particular session:
1470: number of session. Session 1 was on 1957/05/01.
e: evening (as opposed to n:night, m:morning, d:day)
2011/06/29-30: date
22:20–00:15 EDT: local time
Foxmead POD: location
8: sky conditions using Leo Enright's scale
28cmsc: instruments used: 28cm Schmidt-Cassegrain]

Saturn: 175x
Porrima: clean split at 175x
Antares: could not see Antares B at 175x

[Observation of RS OPH was deleted because it was discrepant, probably because thin clouds moved in during observation.]
I saw at least 6 satellites less than 8th magnitude pass through 70x field of view while observing variables.
Deep sky: Messiers 51/NGC5195: observed briefly, but passed behind house while I was switching to higher magnification to observe supernova.
Doubles: Kappa Boo, Epsilon Boo, 35 Com.
Temperature: +12°C


  1. Do you have a link describing "Leo Enright's scale"?

  2. From Leo Enright: Beginner's Observing Guide (RASC):

    0 = almost totally overcast
    1 = very cloudy
    2 = mainly cloudy
    3 = partly cloudy
    4 = city: very hazy/murky
    5 = city: hazy/murky
    6 = city: slightly hazy/murky
    7 = city: acceptably clear
    8 = dark: quite clear
    9 = dark: very clear
    10 = absolutely fantastic
