Ecological Solutions and Evidence, Volume 6, Issue 2, April–June 2025.Venn Diagram of fish species captured by seining and electrofishing. The 10 most frequent species captured in the watershed are represented in the overlapping area as well as an outline of the state of Michigan with the Rouge River watershed highlighted. Both sides have a picture of method collection with a darter on the seining side and a trout on the

Review of asteroid, meteor, and meteorite‐type links
Meteoritics &Planetary Science, Volume 60, Issue 4, Page 928-973, April 2025.Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.

Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT The discovery of radio‐quiet, x‐ray thermally emitting isolated neutron stars (XINSs) in the ROSAT All‐Sky Survey revealed a previously overlooked component of the neutron star population. Advancements in x‐ray instrumentation and the availability of deep, wide‐area optical surveys now enable us to explore XINSs at fainter x‐ray fluxes and ...

On reference star recognition and identification
Geodesy and Cartography, 2014 The paper deals with a research in the area of automation of positional star observations. In order to fully employ recent progress in imaging technologies, star image recognition and reference star identification process should gain comparable level of ...

Astrometry with Small Telescopes [PDF]
Symposium - International Astronomical Union, 1986 At the Quonochontaug Observatory of the University of Rhode Island, we specialize in the development of simple seeing limited optical telescopes. Our main instrument is a heavy Serrier trussed f/10.7, .4-m astrometric reflector which provided the last-minute astrometry in the successful prediction of the occultation of SAO 120774 by Herculina in 1978 ...

Astrometry with Schmidt Telescopes [PDF]
International Astronomical Union Colloquium, 1984 Photographic astrometry, including work with Schmidt telescopes, can be divided into two main fields, (i) the measurement of positions of objects relative to a reference frame of stars with known celestial coordinates, and (ii) the measurement of relative proper motions and trigonometric parallaxes from a series of plates taken on the same field.

Astrometry And Data Centers [PDF]
Symposium - International Astronomical Union, 1988 SummaryThe paper tries to provide some background to answer the problem if old astrometric data should be stored. The cases of the AC and the CdC are examined, as well as the storage of some more recent catalogues on optical disc. Finally the necessity of producing general catalogues (of the SAO type) for non-astrometrists is underlined, to satisfy the

DataWe present a curated, openly accessible dataset of 71 regional meteor events simultaneously recorded by optical and infrasound instrumentation between 2006 and 2011. These events were captured during an observational campaign using the all-sky cameras of
