This is a recent discovery; it seems to have surfaced on the internet just this weekend. The papyrus is not yet but soon to be published by Prof. Dirk Obbink in the ZPE. The Greek, with an Italian translation, can be found here. Here is my translation:

…

But you were always repeating that Charaxus was coming with a full ship; that, I suppose, Zeus knows, and all the gods; but you shouldn’t think this

but send me, as well, and bid me beseech Queen Hera with many prayers that Charaxus arrive here with ship intact

and find us safe and sound; all the rest let us leave to the divinities - for fair weather arises suddenly from great squalls.

They for whom the King of Olympus wishes to send round a daemon to be their helper out of toils, they prove to be happy and very blessed.

We too - if Larichus should lift his head and ever become a man - surely we too would suddenly be delivered from many bouts of despondency.

EDIT: There is some doubt as to whether this fragment is indeed the work of Sappho, or if it may be a forgery of later (but still ancient) date. This article (in Dutch) addresses some of the issues. For my part, I’m inclined to take an agnostic stance.
