Abstract:
K2's Campaign 9 (K2C9) will conduct a ∼3.7 deg2 survey toward the
Galactic bulge from 2016 April 22 through July 2 that will leverage
the spatial separation between K2 and the Earth to facilitate
measurement of the microlens parallax πE for ≳170 microlensing
events. These will include several that are planetary in nature as
well as many short-timescale microlensing events, which are
potentially indicative of free-floating planets (FFPs). These
satellite parallax measurements will in turn allow for the direct
measurement of the masses of and distances to the lensing systems. In
this article we provide an overview of the K2C9 space- and
ground-based microlensing survey. Specifically, we detail the
demographic questions that can be addressed by this program, including
the frequency of FFPs and the Galactic distribution of exoplanets, the
observational parameters of K2C9, and the array of resources dedicated
to concurrent observations. Finally, we outline the avenues through
which the larger community can become involved, and generally
encourage participation in K2C9, which constitutes an important
pathfinding mission and community exercise in anticipation of WFIRST.
Description:
The deadline for adding events to C9a was 2016 March 1 and for C9b it
was 2016 April 25. In total, 34 and 61 ongoing events were added to
the target list for C9a and C9b, respectively.
Table 2 provides a list of the event names, coordinates, and baseline
I-band magnitudes for all of these events, many of which were added to
the target list for both halves of K2C9. This resulted in 70 unique
events that were added to the target list and for which data were
downlinked for at least one half of K2C9.

Note (1): Events are named according to the following convention:
Survey-Year-Field-Index, where the field designation "BLG" refers to the
Galactic bulge.
For events discovered by multiple surveys, the event is named according to
which survey alerted it first.
Note (2): Coordinates and magnitudes are taken from the OGLE Early Warning
System (see Section 5.1).
Note (3): This includes the flux of the source as well as any blended stars.
