Earth is pretty much alone in the solar
system now until the June Solstice.
Mercury and Venus line up with Neptune
and a few days early in the month, Uranus. If these alignments trigger any
sunspot formations it will be a few days until they become visible from
Earth, as the Sun rotates around.
So there may be sunspots visible
starting the 7th and continuing for a few days. If they are formed on both
sides of the Sun then, in a week or so, sunspots from the far side of the Sun
will rotate into visibility on the Earth side of the Sun.
In the first week of May, Mercury and
Mars will line up.

An event of interest may be the
alignment of Earth with the newly discovered planet, Eris. However there may
not be any noticeable change in solar activity as Eris is way off the pane
of Ecliptic and very far away. I was unable to find the exact position where
the longitude of Eris intersects the plane of the Ecliptic. One source said
it was between 20° and 30° of Aries. If there is an increase of solar
activity look for it between April 9 and April 29th.
Also if there is any psychological
influence it might show up as well, though this may take years to figure
