The observer is on Earth at a point with coordinates 55 ° N. w., 83 ° E What time will the observer’s watch show during the upper climax of the Sun on the summer solstice, if this observation point belongs to the fifth time zone?

The longitude of the observation point is 83 ° or 5h32m. This is exactly how noon at this point will occur earlier than at the prime meridian. Neglecting the equation of time, we find that noon at the observation point will come at 6h28m UTC (or the time of the prime meridian). Judging by the coordinates of the point, it is located on the territory of Russia, and the difference between standard and universal time at this point on the day of the summer solstice is 7 hours: 5 hours in accordance with the time zone number plus 1 hour (daylight saving time) and another plus 1 hour (summer time). time). As a result, the upper culmination of the Sun at this point will be observed at 13h28m.
