... 1.10.2012 . ... Credit Copyright: Ligustri Rolando Explanation: Could this dim spot brighten into one of the brightest comets ever? ... Sky enthusiasts the world over are all abuzz, though, from the more optimistic speculations -- that the newly discovered C/2012 S1 (ISON) could develop a spectacular tail or briefly approach the brightness of the full Moon toward the end of 2013. ... In early 2013 October it will pass very near Mars and possibly be visible to rovers and orbiting spacecraft. ...

... Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. ... Introducing Nova Velorum 1999 . ... Explanation: A bright nova was discovered Saturday that is currently visible to the unaided eye in southern skies. ... The last nova this bright was Nova Cygni 1975 , which peaked just brighter than magnitude 2. Nova Velorum 1999 is brighter now than the well-studied Nova Cygni 1992 ever appeared . ...

... As of October 1, 2009, the global rate for the STIS NUV-MAMA dark current has still been occasionally reaching values as high as 13500 counts/s. This high dark current will force use of a signficantly smaller buffer time than would be otherwise needed, and in many cases may push the count rate high enough to make time-tag observations impractical. ... However, we instead found for the NUV MAMA detector an initial global dark rate of between 9000 and 18000 counts/s (a mean of 0.013 counts/s/pixel). ...

. The following is a list of the currently installed versions of the CIMA. The links refer to the CIMA version log page . Normal: version 3.0 - this is the next version of CIMA which has become the new default version --- NOTE that this version uses a new syntax for command file observations, uses new configuration files and needs source files with full velocity information . Old: version 2.2 - this is the old version of CIMA You can return to the main CIMA page by clicking here .

The C component of Comet Schwassmann-Wachmann 3 . imaged by Apostolos Christou of Armagh Observatory on 4th April, 2006. ... About one month after its discovery the comet reached its closest point to the Earth (5.73 million miles). ... Current calculations indicate that the main component of the comet, designated SW3C, may reach maximum brightness around May 15th when its distance from the Sun and Earth will be about 93 million miles and 7.5 million miles, respectively. ...

XMM­Newton CCF Release Note XMM­CCF­REL­228 pn modified Timing mode response matrix M. Kirsch July 10, 2007 1 Purpose Using the EPIC­pn CCD camera in Timing mode, in which data are read out continuously, telemetry constraints do not allow full use of the capabilities for very bright sources because currently randomly distributed data gaps are introduced by the on­board data handling electronics. ... Lower: same but using the new modified matrix for the modified Timing mode (red). ...

The debate between proponents of a static corona, Parker's solar wind theory, and an alternative "solar breeze" theory of Chamberlai n [1960, 1961; Dessler 1967] was only settled by observations from space. ... Rapidly spreading plasma clouds produced by solar flares, like those envisioned by Chapman and Ferraro, are sometimes superposed on the solar wind flow. ...

In October last year I made the tough decision to leave astronomy, after 11 years and 4 postdocs in three different countries. ... In this talk I will describe my journey from academia to industry, outline what a day in my life as a data scientist is like, and discuss the outlook for data science over the next few years. I will also suggest how someone from an astronomy background can best prepare themselves for a similar transition into data science. ...

... What is the configuration of the device driver software? ... If the software you use doesn't adequately tell you what's wrong (or automatically configure it correctly) then you need to investigate how your hardware devices and their drivers are configured. ... Another problem is that when you view configuration messages on the screen, it's sometimes not clear whether the reported configuration is that of the device driver, the device hardware, or both. ...

... The star formation rate (SFR) of the current SF episode can be estimated from the total H luminosity. ... For the derived total flux F (H )=5.8 erg s -1 cm -2 we obtain a total H luminosity of 10 39 erg s -1 . ... The total mass of ionized gas can be obtained from the average mass density inside the H II region and its volume. An average mass density corresponding to the average electron density of 1 cm -3 within a volume with a diameter of 0.5 kpc yields a total ionized gas mass of 10 6 . ...
