L990923000:06:42Rayleigh HG adjusted53360EG
L990923000:10:55Dye system tuned to 589.158 nm53360EG
L990923000:13:04Rayleigh SR430 frosen. toggled power ans started program0EG
again incremented
L990924000:13:57running again53360EG
L990924000:30:55looks like I lost on Rayleigh reckord on johns display?69360EG
L990924002:08:36there are some small,thin but definite protrutions out 0EG
of the normal sodium layer
L990924002:22:19Dye system tuned to 589.159 nm, wavemeter indicated0EG
589.161 (the system had drifted)
L990924002:30:55there may be some background in the current and last two 0EG
integrations, turned on the light in the sodium room!
L990924002:37:46Stable sodium again. The drift is in the wavemeter, the tuning68190EG
before only made the counts worse. tuned back to the old
indication of 589.161 and got to the count seen before
L990924002:39:40smashing Rayleigh counts!!!68190EG
