Coordinate Observation: Y

Observatory: DSN
Description: We will be simultaneously observing the source in the radio band with the Deep Space Network radio telescopes (DSS-14 and DSS-63) on May 22-23 20:00-02:00 UTC, May 23 12:00-17:00 UTC, May 28-29 19:00-02:00 UTC, and May 29 16:00-20:00 UTC, for a total duration of 22 hr.

Uninterrupted: Y

Justification: We request uninterrupted, long duration exposures spanning (> 1 hr) whenever possible to help with DSN scheduling, and burst and periodicity searches.
