We report the characterization of a genomic clone containing portions of two tandemly arranged genes that encode a spicule matrix protein, SM30, of the sea urchin Strongylocentrotus purpuratus. The isolated 18.4-kilo-base genomic clone contains the complete genomic sequence of one SM30 gene, designated SM30-alpha, and a portion of another SM30 gene, designated SM30-beta.

We examine spectral time series of coronal line Mg ix 368 A and transition region line O v 629 A, observed with the Coronal Diagnostic Spectrometer (CDS) onboard the SOHO spacecraft. Primarily we were looking for intensity and velocity oscillations in polar plumes, however by chance we detected a giant macro-spicule at the limb and were able to follow its dynamical structure. Blue and red-shift...

We explore joint observations of the South-East limb made by Hinode, TRACE and SOHO/SUMER on April 12, 2008 as part of the Whole Heliosphere Interval (WHI) Quiet Sun Characterization targeted observing program. During the sequence a large, 10Mm long, macro-spicule was sent upward and crossed the line-of-sight of the SUMER slit, an event that affords us an opportunity to study the coupling of co...

We study a solar spicule observed off-limb using high-resolution imaging spectroscopy in the Ca II 8542 \AA\ line obtained with CRisp Imaging SpectroPolarimeter (CRISP) on Swedish 1-m Solar Telescope. Using new version of non-LTE code NICOLE specifically developed for this problem we invert single- and double-peak profiles. This considers geometry computes atomic populations by solving 1D radia...
