NOAA-19 SBUV (Solar Backscatter UltraViolet Instrument) continued its OV sequence. On 3 April 2009, the memory values (segments 1-3, positions 1-12) were programmed for the 2-step wavelength calibrations. These 2-step wavelength calibrations will take place on 14 April 2009. On 7 April 2009 (15:04 UTC), the SBUV Range-3 was switched from Anode Mode to Cathode Mode for a 3 day collection; it will be returned to Anode Mode on 10 April 2009 at approximately 14:32 UTC. Additional calibrations on schedule for 14-17 April 2009 include Diffuser Decontamination, Solar Calibrations, Goniometric Calibrations, and Wavelength Calibrations. NOAA-19 ESA coefficients analysis/adjustments investigation continues. There are numerous SBUV Position Mode Solar Observations on schedule for 21-23 April 2009 to assist in the investigation. NOAA-19 COMM testing was completed.
