The Arecibo Legacy Fast ALFA Survey

ALFALFA Fall Semester 2011

Because ALFA was being serviced, we started the "fall" season later than originally planned in September 2011. However, as of October 6th, we had completed the zenith strip of tiles with only the region north of Dec = +32^o left to finish. However, the bad news was that we finished the 2011 fall season with more than 25 drifts left to do. (:

We do hope to finish in Fall 2012.

Several ALFALFA datasets are complete and have been published; see the links to Publications and Data above.

The graphical summaries below indicate the A2010 coverage up to and including the fall 2011 observing season. We try to update them regularly, so they include what's currently scheduled (and therefore may or may not happen).

Yellow indicates planned observations in pass 1.
Green indicates completed observations in pass 1.
Gold indicates planned observations in pass 2.
Cyan indicates completed observations in pass 2.
Brown indicates poor quality data (hardware failure, gain instability or unusual rfi)
Pink indicates the area to be covered next
