New HMI Science Nuggets are available at
http://hmi.stanford.edu/hminuggetsfeaturing
#1 "Evidence of Double-cell Meridional Circulation inside the Sun"
contributed by Junwei Zhao
Acoustic travel time reveals an equatorward meridional flow in the middle
of the solar convection zone. Inversion reveals an evidence of double-cell
meridional circulation inside the Sun.

closely related to HMI science objectives, to contribute to the HMI science

#2 "Testing Hemispheric Rule of Helicity with HMI Data" contributed by Yang
Liu
Hemispheric helicity preference in groups of active regions with different
properties suggests different origins of magnetic twist.

#3 "The Biggest Sunspots Produced by Cycle 24" contributed by Aimee Norton
Even though Solar Cycle 24 is weak, it has still produced some large
sunspots. We list the largest sunspots as observed by HMI and discuss some
aspects of the data.

#4 "SDO/HMI Observations Create New Challenge to Solar Meridional
Circulation Theories" contributed by Mausumi Dikpati
Solar meridional circulation, if mechanically driven and thermally
braked, contains two cells in latitude; generating two cells in depth,
recently observed by SDO/HMI, is a new challenge to theory.

#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.

#6 "Fickle Fields: Are Transient Magnetic Reversals Real?" contributed by
Brian Harker
We present observations from SDO/HMI of a magnetic transient observed in
NOAA 11429 during the M7.9 flare on 13 March 2012. The observed transient
showed an impulsive rotation of the field vector in response to the
white-light flare.

#7 "Measuring the Solar Radius with HMI during the Venus Transit of 2012"
contributed by Sebastien Couvidat
The Venus transit of 2012 allowed us to measure the solar radius around
6173Å with HMI: we obtained a value of 959.58″ at 1 AU, with a systematic
uncertainty larger than 0.27″.
