Where is the Earth in its orbit around the sun when this event happens? For half of each year, the sun is closer to Voyager 1 than is the Earth.
Also, does anyone know how long communication with the probe is disrupted when the sun is directly between them?
Both Voyagers left the ecliptic plane with their final gravitational slingshots (Voyager 1 went north, Voyager 2 went south so only the Canberra radio dishes can communicate with it) so even when Earth is further from them than the sun there's 35 degrees of separation.
