#5 "Comparison of sunspot properties in cycle 24 and 23"
contributed by Reza Rezaei

We analyze umbral area, magnetic field, and umbral intensity of the
sunspots during the rising phase of cycle 24. We do not find a significant
variation in either sunspot physical properties or distribution of sunspot
umbral area from previous cycles.

We invite those who use HMI data for their research, or whose research is
closely related to HMI science objectives, to contribute to the HMI science
nuggets.   -- SDO/HMI team
