Multi-Beam Data Recorder Status
* The SETI multibeam data recorder collects data by piggybacking on the Arecibo ALFA receiver. ALFA is one among several receivers at Arecibo (there are transmitters as well) and is only turned on part of the time. The data recorder usually runs at all times but only records data when the ALFA receiver is on. At other times the recorder idles but watches for ALFA to come on, at which time recording resumes.

Signals Already Found at Current Telescope Sky Position¹
¹ All signals previously found by SETI@home that fall within of where Arecibo Observatory is currently pointing (coordinates taken 25618906 minutes ago). If we are recording data, these numbers will eventually increase.
² Multiplets are groups of signals of the same type seen over multiple different observations which also fall within a small frequency window (). They are statistically common, even in random noise, and typically are caused by RFI, but nevertheless score better when compared to lone signals.
³ Star data are from the Hipparcos Star Catalog. This is the number of known stars seen at this pixel. The pixels are small enough that we average about one star for every 150 pixels. We will divide this star count into more specific classes at a later date.
