    I am well versed in Fog.. and the weather.. Definitely location dependant.. 
     
    We have been fogged in nightly for over a month.. Up until the last two
    days, as a high pressure system has parked itself right over us. This is
    actually quite impressive, or was yesterday, as the satellite image showed
    all forms of clouds moving away from the SF Bay Area..  Temp is 15 -20
    degrees hotter than yesterday, with another 5 degrees tomorrow.. Heat
    Advisory for 105+ on Tuesday..
     
    This was my point.. The Marine layer is currently non existent along the CA
    Coast.. It will be back in a few days, but seeing OTV is not an issue until
    then, as noted by my timing of it this AM..I actually missed he previous
    pass I was aiming for, but that just left me ready for the better, following
    pass..
     
    Yes.. "Gilroy Area".. 10 miles North.. South side of Chesbro Reservoir in
    Morgan Hill..
    Gilroy is constantly fogged in lately, causing me to end up being fogged in
    from the Southeast..
     
    Of course CA is a big state, and I have no idea where Brooke and her friend
    live. But the SF Bay Area is cloud and fog free.. and baking for a few
    days.. Mind you this is by FAR the coolest Summer in the SF Bay Area that I
    can remember... (Born here..)

    marine fog is dependent upon location, upwelling, tides, and a few other
    factors. Location being the most important for observations. I think inland
    a few miles from the coast (San Francisco/south bay area) most likely is not
    an issue. The marine layer is most affected by high pressure areas in-land,
    pulling in cooler pacific area. This is an evening phenomena for the most
    part, but could happen anytime weather conditions permitting. I see Derek
    hasn't experienced any of this. Gilroy area - right?

    I ask because my friend with the good telescope says X37B is up around 4 
    am California time, but that's not a good time to image it because the 
    marine layer (fog) is dense then.

    Ummm.. Not for the last two days or even the next 2 days..
    
    For all things Satellite, Heavensat fits the bill..

    Hi:
    
    If a satellite is on the dark side of the Earth at some later time the
    (1) Sun will rise on the satellite, yet the sub nodal point will be in 
    the dark.
    Later the (2) Sun will rise on the current sub nodal point and later the (3)
    Sun will be South of the sub nodal point, later the (4) Sun will set on the
    sub nodal point and finally the (5) Sun will set on the satellite.  Is there
    a graphical 
    representation of these 5 key points?
    I ask because my friend with the good telescope says X37B is up around 4 
    am California time, but that's not a good time to image it because the 
    marine layer (fog) is dense then.  Knowing these 5 key points on the 
    orbit would tell you not only when it would be a good time to look for 
    the satellite but also when the satellite would have a good view of the 
    Earth.
