    Blinkers are brightenings at network cell junctions that are traditionally identified with SOHO/CDS and explosive events or high velocity events are identified in high resolution UV spectra obtained from HRTS and SOHO/SUMER. ...
  • Metcalf, Thomas; Fletcher, Lyndsay; Brown, Daniel; Alexander, David; Ryder, L. (2001-06-10)
    Based on a multiwavelength data set and a topological model for the magnetic field, we argue that a M1.9 flare which occurred on 1993 May shows evidence of three-dimensional coronal reconnection in a spine-fan configuration. ...
  • Golub, Leon; Brown, Daniel; DeLuca, Ed; McMullen, Rebecca; Parnell, Clare (2001)
    Abstract. X-ray bright points are small dynamic loop structures that are observed all over the solar corona. The high spatial and temporal resolution of the TRACE instrument allows bright points to be studied in much greater ...
  • Title, Alan; Carolus, Thomas; Shine, Richard; Wolfson, C. Jacob; Nightingale, Richard; Schrijver, Carolus; Brown, Daniel; Alexander, David (2003)
    Recent observations from TRACE in the photospheric white light channel have shown sunspots that rotate up to 200° about their umbral centre over a period of 3-5 days. The corresponding loops in the coronal fan are often ...
  • Brown, Daniel; Schrijver, Carolus (2000-06-27)
    The magnetic field in the outer solar atmosphere is frequently distorted by flares. In some cases, a fraction of the field exhibits a rapidly damped oscillation (Schrijver et al.; Aschwanden et al.). If this is a resonating ...
  • Maclean, Rhona; Beveridge, Colin; Longcope, Dana; Brown, Daniel; Priest, Eric (2005-07-08)
    The magnetic breakout model gives an elegant explanation for the onset of an eruptive solar flare, involving magnetic reconnection at a coronal null point which leads to initially enclosed flux 'breaking out' to large ...
  • Brown, Daniel; Priest, Eric (2001-02-03)
    Many traditional two-dimensional models of flares and other reconnective events rely on an X-point in the corona which collapses to form a current sheet where reconnection takes place. However, the Sun's corona is ...
