Requested Time and Moon Phases

On the application form, the PI is asked to specify the number of hours or nights requested. This can be structured, if desired, into Dark, Grey, Bright time. For this, we follow the definitions given in a study by Ian Skillen (Isaac Newton Group of Telescopes) and we adopt the following ranges of Fractional Lunar Illumination (FLI):

 

Dark:

0.00

FLI

0.25

Grey:

0.25

FLI

0.65

Bright:

0.65

FLI

1.00

 

Of course, “Any” means that any of Dark, Grey, Bright is acceptable. Under “Total”, the PI shall input the sum of all Dark, Grey, Bright times.
