| DFT of the data sets shown below. DFT suggests two closely
spaced frequencies of 7.2811 and 7.5122 c/d |
 |
| Data from the evening of Jan 18/19. Bright sky conditions
but clear. |
 |
| Data from Jan 19/20. Excellent conditions at first but observations
were eventually terminated by cloud! |
 |
| Data from Jan 27/28. Good conditions - aurora at times bright |
 |
| Data from Jan 31 - Feb 1. Very Good conditions at the beginning
of the night with cloud at the end. Scatter (C2-C1) varied from <0.008
mag to 0.017 mag overall. |
 |
| Data from Feb 1/2 Very Good conditions at the beginning of
the night (scatter (C2-C1) <0.008 mag) but ended abruptly with cloud
after approx. 1 hour! |
 |
| Data from Feb 3/4 Fair- Good conditions (scatter (C2-C1) <0.015
mag) but frosty with active aurora at times. C2-C1 displays a curious dip
(eclipse?) at the end of the evening. |
 |
| Data from Feb 5/6 Fair- Good conditions (scatter (C2-C1) <0.015
mag) but frosty with active aurora (ICB2-3) at times extensive. |
 |
| Data from Feb 10/11. Clear and cold (-25C). Very good conditions
but scatter in C2-C1 somewhat high (0.02 mag). BY Cam appears to be brightening
toward end of evening and is approax 1 mag brighter than on Feb 5/6 |
