NOTICE: Mercury moves too quickly for a table like the one on the right to be useful. Instead, consult the table above. Within a week of the dates given above, Mercury will be visible as a moderately bright star low on the western horizon, just before sunset. About six weeks after these dates, it is visible in the east just before sunrise. The dates in boldface (late spring) offer the best viewing for observers in the northern hemisphere, with Mercury sitting nearly 20 degrees above the horizon at sunset.
