Swift has been monitoring the accreting millisecond pulsar IGR J17498-2921 since the start of its outburst in 2011 August 12 (ATels #3551, #3555, #3556). We detected two X-ray bursts on Aug. 18 and 28. During the first ~12 days the average persistent XRT count rate remained approximately constant at 3-7 c/s. Around Aug. 24 the source count rate

The Observatorio Astrofísico de Javalambre (OAJ) is a new astronomical facility located at the Sierra de Javalambre (Teruel, Spain) whose primary role will be to conduct all-sky astronomical surveys. The OAJ facility will have two wide-field telescopes: the JST/T250; a 2.55-m telescope with a 3° diameter field of view (FoV), and the JAST/T80; an 0

The Taiwan Oscillation Network (TON) is a ground-based network to measure solar intensity oscillations to study the internal structure of the Sun. K-line full-disk images of 1000 pixels diameter are taken at a rate of one image per minute. Such data would provide information onp-modes withl as high as 1000. The TON will consist of six identical

We propose to observe the newly-discovered transiting planet TrES-1 during the time of secondary eclipse (when the planet passes behind the star). A successful measurement of this eclipse would constitute the first direct detection of emission from an extrasolar planet. The secondary eclipse will reveal two key quantities of the planet: its

Context. The MOVIS catalog contains the largest set of near-infrared (NIR) colors for solar system objects. These data were obtained from the observations performed by VISTA-VHS survey using the Y, J, H, and Ks filters. The taxonomic classification of objects in this catalog allows us to obtain large-scale distributions for the asteroidal

In this paper we approach the astronomy teaching process for students in computer sciences through a controlled investigation method using real astronomical data, including data reduction and quality control of the astrometry of near-Earth asteroids. The method used data collected on the Isaac Newton Telescope located at the ORM observatory on the
