Based on observations obtained with the Solar and Heliospheric Observatory SOHO joint observing program for velocity fields in sunspot regions, we have detected 3 min transition region umbral oscillations in NOAA 8156. Simultaneous recordings of O V λ629 and N V λ1238, λ1242 with the SUMER instrument give the spatial distribution of power in the 3 min oscillations, both in intensity and line-of...
متن کاملSunspot Rotation and the M-class Flare in Solar Active Region NOAA 11158
In this paper, we measure the rotation of a sunspot in solar active region NOAA 11158 (Solar Target Identifier SOL2011-02-15) that was associated with an M-class flare. The flare occurred when the rotation rate of the sunspot reached its maximum. We further calculate the energy in the corona produced by the sunspot rotation. The energy accumulated in the corona before the flare reached 5.5× 10 ...
متن کاملTransition-region Velocity Oscillations Observed by Eunis-06
Spectroscopic measurements of AR NOAA 10871, obtained with the Extreme Ultraviolet Normal Incidence Spectrograph (EUNIS) sounding rocket instrument on 2006 April 12, reveal velocity oscillations in the He II 303.8Å emission line formed at T ≈ 5 × 10 K. The oscillations appear to arise in a bright active-region loop arcade about 25 wide which crosses the EUNIS slit. The period of these transitio...
متن کاملLetter to the Editor Oscillations of sunspot magnetic fields
We report on velocity and magnetic field oscillations observed in sunspots using the MDI instrument onboard SOHO. In addition to the well-known velocity oscillations, the data clearly show highly localised oscillations of the magnetogram signal in different parts of the sunspots. We show that only oscillations of the magnetic field vector can produce the observed magnetogram oscillations, and t...
متن کاملNoaa 7978 : the Last Best Old - Cycle Region ?
Sunspots in NOAA active region 7978 rst appeared on July 6, 1996, while the region was at E15. The spots reached an area of 400 millionths within four days and the active complex remained interesting for at least ve solar rotations, generating an X class are, a long-duration event, and coronal mass ejections well-observed by both Yohkoh and SOHO. During these ve rotations, only a few short-live...
