Current UKIRT Seeing

(Reload page to get the current plot)
Plot of current seeing


The data shown (if any) are either (1) the recorded ZRMS from UKIRT focus measurements for the current UT date converted to the equivalent K band (2.2 microns) seeing at zenith (Cass K band seeing) or (2) direct WFCAM K band seeing measurements, again corrected to zenith (WFCAM K band seeing) . Please see Seigar et al, 2002, Proc. SPIE, 4844, 366 for more information on UKIRT's ZRMS measurements.  If no data appear then no focus measurements have been taken during the current UT date. Please also note that WFCAM data are taken with 0.4 arcsec pixels.
