Solar jets occur throughout the solar atmosphere, including in coronal holes, quiet regions,
and active regions. Observations at X-ray and EUV wavelengths show that frequently
jets are made by eruptions of small-scale filaments, called “minifilaments.” Recent studies
indicate that many of, or even the majority of, these jet-producing minifilament eruptions
occur at locations where opposite-polarity photosphere magnetic fluxes merge and cancel.
These observations support the idea that flux cancelation builds a magnetic flux rope along
which cool minifilament material gathers, and that the flux rope subsequently erupts to form
the jet through a sequence of magnetic reconnections. In this presentation we will update
our recent investigations into jets, and discuss expectations and needs for jet studies with
new Sun-observing instruments.
