This web page summarizes my observations of Ceres during the 2014 opposition. I present solutions for H & G, for each of the six Framing Camera "color" filter bands. Geometric albedo versus rotation phase is presented for each band.
Recent Update History
2015.01.13 Added link to calibration description web
page: link
(in progress)
2015.01.11 Added HG plot with
rotation variation removed; scatter is slightly better
2015.01.10 Added new data file
(DR20150110), plots of H(WL) and G(WL), & plot pairs
showing phase functions and brightness variation with rotation
for each FC band.
2014.09.17 Updated flux table
txt-file (DR20140916); added phase function plot.
2014.06.15 Completed observations and
analysis of Ceres FC observations.

H & G vs. Wavelength
The two plots are based on BLG data only. JYL plot points are based on a data file that had the wrong phase angle listed for May 8 data, so I need to update those points. The H values are in excellent agreement, while the G values are slightly different. This might be caused by the bad May 8 phase angle, so the JYL G points should be updated.

Geometric albedo spectrum for selected phases from all data to
date (Mar 20 to Jun 13), using a phase parameter G shown in
the next graph.
