Proposals to observe with Hubble Space Telescope (HST) are reviewed in two phases managed by the Space Telescope Science Institute (STScI). In Phase I, proposers submitted an Observation Summary for review by the Telescope Allocation Committee (TAC). The Observation Summary provides only general descriptions of the targets and of the proposed observations. The TAC review results in a list of accepted proposals.

During Phase II, General Observers (GOs) with accepted proposals, as well as Guaranteed Time Observers (GTOs), must provide complete details of their proposed observations so that STScI can conduct a full technical feasibility review. The Phase II information will then be used to schedule the actual observations and obtain data.

This document, the Phase II Proposal Instructions, has the following purposes:

•	To describe the information that must be submitted to STScI by GOs and GTOs during Phase II.

•	To describe what you have to provide in APT (Astronomer’s Proposal Tool).

•	To show how to submit the information to STScI.

Readers of this document should be familiar with the Cycle 21 Call for Proposals, issued in December 2011, and with the Instrument Handbooks.
