03 Mar '14

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. 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 >

New HMI Science Nuggets are available at http://hmi.stanford.edu/hminuggets, featuring the following topic #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. 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

New HMI Science Nuggets are available at http://hmi.stanford.edu/hminuggets, featuring the following topic #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. 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

03 Mar '14

New HMI Science Nuggets are available at http://hmi.stanford.edu/hminuggetsfeaturing #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 >

03 Mar '14

New HMI Science Nuggets are available at http://hmi.stanford.edu/hminuggets, featuring the following topic #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. _________ 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
