    Notes: Abstract Geomagnetic storm-time variations often occur coherently at high latitude and the day-side dip equator where they affect the normal eastward Sq field. This paper presents an analysis of ground magnetic field and ionospheric electrodynamic data related to the geomagnetic storm which occured on 27 May 1993 during the International Equatorial Electrojet Year (IEEY) experiment. This storm-signature analysis on the auroral, mid-latitude and equatorial ground field and ionospheric electrodynamic data leads to the identification of a sensitive response of the equatorial electrojet (EEJ) to large-scale auroral return current: this response consists in a change of the eastward electric field during the pre-sunrise hours (0400–0600 UT) coherently to the high-, mid-, and equatorial-latitude H decrease and the disappearance of the EEJ irregularities between the time-interval 0800–0950 UT. Subsequent to the change in h’F during pre-sunrise hours, the observed foF2 increase revealed an enhancement of the equatorial ionization anomaly (EIA) caused by the high-latitude penetrating electric field. The strengthening of these irregularities attested by the Doppler frequency increase tracks the H component at the equator which undergoes a rapid increase around 0800 UT. The ΔH variations observed at the equator are the sum of the following components: SR, DP, DR, DCF and DT.

    Notes: The nucleotide sequence of a 5 kb EcoRI-NcoI fragment of chromosome IV, contiguous to gene POL3 (CDC2), has been determined. It contains three open reading frames: QRI1, QRI2 and QRI7. Two of them are essential genes. QRI7 is homologous to the Escherichia coli orfx gene. Accession number to EMBL/Genbank Data Library is X79380.
