We have conducted a Galactic plane survey of methanol masers at 6668 MHz using a 7-beam receiver on the Parkes telescope. Here we present results from the first part, which provides sensitive unbiased coverage of a large region around the Galactic Centre. Details are given for 183 methanol maser sites in the longitude range 345◦ through the Galactic Centre to 6◦. Within 6◦ of the Centre, we fou...
Spectra from two decades of zonal current data at $$\sim $$ 4000 m in the central and western equatorial Indian Ocean show a shift dominant frequencies west to east. The 120–180-day period is stronger 77 $$^\circ E, 60–120-day 83 30–90-day 93 E. weakening lower near eastern boundary can be explained using theoretical ray paths Kelvin waves reflected Rossby waves. wave forced by winds reflects a...
Position calculations, e.g. adding, subtracting, interpolating, and averaging positions, depend on the representation used, both with respect to simplicity of the written code and accuracy of the result. The latitude/longitude representation is widely used, but near the pole singularities, this representation has several complex properties, such as error in latitude leading to error in longitud...
[1] An extended series of FUV images obtained on 7 days during winter 2000–2001, with fixed pointing, yielded highly accurate tracking of emisson features as Jupiter rotated. They provided newly detailed measurements of the degree of corotation of auroral emissions and their variations with changing central meridian longitude. This 2-month data set provides a statistical average location of the...
Abstract We update observed temperature trends in the Mediterranean and Middle East–North Africa (MENA) region, assess their temporal spatial features investigate possible influences from urbanisation. Monthly mean time-series of 370 stations are acquired CRUTEM4.6 GSOD datasets converted into suitable format for statistical analysis. The calculated annual seasonal linear 1981–2020 indicate a s...
The Antarctic Slope Current (ASC) and Coastal advect heat, freshwater, nutrients, biological organisms westward around the margin, providing a connective link between different sectors of continental shelf. Yet strength pathways connectivity continent, timescales advection, remain poorly understood. We use daily velocity fields from global high-resolution ocean-sea ice model, combined with Lagr...
The space missions MESSENGER and BepiColombo require precise short-term studies of Mercury’s rotation. In this scope, we perform analytically and numerically by Hamiltonian approach a synthetic 2-dimensional representation of its rotation, using complete ephemerides of the orbital motions of the planets of the Solar System. This representation allows us to derive the librations in longitude and...
Landscapes surrounding agroecosystems can provide resources that may benefit insect pests. This project examined the influence of landscape on abundance and spatial pattern Popillia japonica (Coleoptera: Scarabaeidae) in vineyards. Twenty vineyards across Southern Wisconsin, spanning a gradient 5-80% cropland 1.5km radius landscape, were sampled 2017 2018 for P. adults leaf injury. The distribu...
