The inbound Planet X (aka Nibiru, 12th Planet, Marduk, etc.) cannot be viewed from Earth during part of the Earth's orbit around the Sun, as those gazing in that direction must look past the sun, during daylight, and light polution virtually eliminates the ability to even see bright stars. This is termed being "in the sun" by astronomers. Where ZetaTalk has stated that amateurs will be able to see it with their scopes by mid-year 2002, the spot in the sky to be viewed will only be in darkness the hour before dawn at best by very late summer to very early Fall, but by December will be visible for most of the night.
The chart below was garnered from dates, times, and cities plugged into SkyMap, and the Coordinates spot Located between the end of Orions bow and a flank of the Taurus bull, and from the NOAA web site which provides sunrise time by city and date. The times posted assume no daylight savings time adjustments. Assume the hour before dawn, at a minimum, to have light pollution affecting something dim and diffuse viewed on the horizon where the Sun will be rising.
