Topband: sunrise

[W7lr at aol.com]

I wonder how the weather man defines or determines sunrise time?  If  we 
lived in Hawaii it might be when the sun appears over the water  horizon.  Here in 
my MT qth we live at 1 mile elevation with nearby  mountains going up to 
11,000 feet.  This morning the paper said 1330z,  which is about the time that 
AH2L peaked to 579.  A half hour earlier Ed  was at the noise level about 449.  I 
suspect that the weather man sunrise  and the sunrise peaks that we 
experience on 160m are not directly related.   We all experience various signal and 
noise peaks or dips, sometimes none, and  sometimes either side of sunrise.  This 
all may be a good NM7M topic?   Can anyone shed light on this?  Thanks.  73
