Following a long period of consensus on the storm-substorm relationship, a dispute on this topic has emerged in recent years. The importance of substorms for the buildup of the terrestrial ring current, which is the major element of magnetic storms, has been questioned in several studies. This paper is an effort to assess the "fine structure" of the storm-substorm relationship, by investigating the correlation between the changes in Dst and the substorm-associated O+ enhancements in the inner magnetosphere during the storm main phase. For this purpose we use energetic ion measurements from the Magnetospheric Ion Composition Spectrometer (MICS) on board the Combined Release and Radiation Effects Satellite (CRRES), and the newly produced high-resolution (5-min) Dst index for the intense storm of June 5, 1991. Substorm signatures from both MICS measurements and ground magnetometers correlate well with changes in the Dst decrease rate. This implies a significant influence of substorm occurrence on storm dynamics. (C) 2000 COSPAR. Published by Elsevier Science Ltd.

We report calibration of the optical instruments of the Optical Mesosphere Thermosphere Imagers (OMTI) using facilities at the National Institute of Polar Research. OMTI has been developed to investigate dynamics of the upper atmosphere through nocturnal airglow emissions. OMTI consist of an imaging Fabry-Perot interferometer, three all-sky cooled-CCD cameras, three tilting-photometers, and a spectral airglow temperature imager (SATI). The all-sky cameras and the photometers have been calibrated using a 2-m integrating-sphere and a spectrometer. Absolute sensitivity and image-flattening data are obtained together with filter transmission functions. Inhomogeneity of transmission function on the filter surface is found from the calibration using the spectrometer. We also find that filters with highly-flattened image-quality surfaces may cause serious Newton's Ring pattern on final images. Examples of the data are shown for the cameras and the photometers based on the airglow observation at Shigaraki (35°N, 136°E), Japan.

Polysialic acid (polySia) is a carbohydrate structure found on neural cell adhesion molecules (N-CAM). Two polysialyltransferases (polySiaTs) that catalyze synthesis of polySia have been described, and designated PST-1/PST/ST8SiaIV and STX/ST8SiaII. We cloned a polySiaT (xSTX) from a nonmammalian vertebrate, Xenopus laevis. xSTX had 80% amino acid similarity to the rat STX. This clone induced polySia expression when transfected into polySia-negative COS-1 cells. Northern blot analysis of whole embryos at different stages of development revealed that xSTX mRNA was most abundantly expressed in premetamorphic stages. The relative level of xSTX and N-CAM mRNAs was also examined and found to change in parallel to the extent of polysialylation on N-CAM. In adult tissues, the expression of xSTX mRNA was restricted to brain, eye and heart, which also expressed polySia. These results suggest that xSTX is the major enzyme responsible for the synthesis of polysialylated N-CAM in embryos at certain stages of development and also in adult tissues.
