* MC #3 reported 00:00 for its times and said: "right now it's light all day, light all night".

** MC #7's sunrise time looks unusual, but it is CORRECT. Sunrise for MC #7 actually occurred just before midnight on the preceding day, 1/31. One way to calculate photoperiod for MC #7 is to calculate how much daylight there was (a) from 23:48 on 1/31 to midnight ; and (b) from midnight to 22:58 on 2/1; then add the two amounts.

*** MC #8 reported 00:00 for its times and said: "right now our night never seems to end".
