I haven't been around s@h website nor the usenet for a while, so this
caught me a bit off guard. I've just downloaded a new batch of WU's, and
the first one to process has RA +37°47'59". I know that there was talk
about expanding the search area, but I haven't seen any news on that,
and so far I haven't had any work units outside the standard search
area. How far behind have fallen with my info, and what is the new
search area?

There's no such thing as a right ascension greater than 24 hours --
note: not degrees! What you're seeing is due to an arithmetical bug
of some kind; subtract 24h to get the correct RA.

AFAICT the "search area" already includes pretty much all of the sky
that's available to the Arecibo dish, a band approximately extending
from the equator to 40°N declination. The data for S@h have mostly
been obtained in a 'piggyback' mode, with the pointing of the
instruments under the control of astronomers making observations for
quite unrelated purposes.

See the whole-sky maps linked to by the "data collection" page at

<http://setiathome.ssl.berkeley.edu/process_page/data_collection.html>;

there's also an explanatory page that includes a description of the
celestial coördinate system.
