The contribution of the modern amateur astronomer to the science of astronomy

Dec 2022
摘要
An amateur astronomer in the modern world has the opportunity not only tomake visual observations for own interest, but can make scientific astronomicalobservations and new discoveries in astronomy. In my example, as amateur astronomer and only through self-education, Iinform about my discoveries: of the possible dwarf nova on the old digitizedphotographic plates and of new variable stars from sky surveys data by means ofdata mining; how I discovered (in the images of the sky surveys): astronomicaltransients, supernovae, planetary nebula candidates and new binary systems inthe data of Gaia DR2; I describe my discoveries of three novae in the AndromedaGalaxy. I report about some of my scientific observations using remote telescopes: ofsuperhumps of cataclysmic variable stars; of echo outburst of AM CVn star; ofmaximum brightness of blazars; of optical afterglows of gamma-ray bursts(including GRB 221009A); of microlensing events; of rotation of near-Earthasteroid 2022 AB. I also describe my photometric follow-up observations ofnovae (including V1405 Cas and V1674 Her) and my astrometric observations ofSolar System objects (including the confirmation of objects posted at theConfirmation Pages of the Minor Planet Center) including observations of comet2I/Borisov, asteroids 2020 AV2 and (65803) Didymos. I also describe some of myobservations of occultations: of the star by asteroid (159) Aemilia, of thestar by Saturn's moon Titan and of Uranus by the Moon during total lunareclipse on November 8, 2022; and visual observations of variable stars, meteorsand sunspots (including during the transit of Venus in 2012). Some of my data already used in scientific papers, others were sent to thedatabases. I share my experience of discovery and research of astronomicalobjects and in my example, I show that an amateur astronomer can make a realcontribution to the science.
