... Precisely one month ago, on 11 July 2009, the last active area of the new solar cycle disappeared from the surface of the Sun. Over the 30 days following this, neither observers on Earth nor devices in space have been able to detect the emergence of any sunspots. ... Therefore, it seems that our star has once again returned to a state of deep solar "winter", following several sparks of activity in May-June 2009. ... To date, this period has lasted 30 days. ...

... With this adjustment, the largest three-month range occurs in February-April and is 71 њF. The range for all year, still removing the January 1962 record low, is 88 њF. The expansion coefficient for aluminum alloy 6061 is 24.3 microns/m-њC while that for borosilicate glass E6 is 2.8 microns/m-њC. The expansion coefficient difference is 21.5 microns/m-њC. Combining this number with the scale factor equation from the previous section gives a coefficient of 0.207 mm/њC for primary motion. ...

The Infrared Supernova Rate . To derive the number of SNe expected in our ground-based data and calculate the IR supernova rate , we have to derive a relation between the luminosity of the galaxies and their Star Formation Rate (SFR) and the shape of the "mean" K-band light curve for a core-collapse SN. ... Rates are generally normalized to the luminosity of the parent galaxy, either the B luminosity of L(FIR). ... For comments please contact: gcresci@arcetri.astro.it . ...

The rates of build-up in the atmosphere of human-made compounds that deplete the ozone layer (e.g., chlorofluorocarbons (CFCs) and halons) have slowed in recent years as a direct result of reductions in global emissions of these compounds. ... The peak global ozone depletions are expected to occur during the next several years. ... Methyl bromide continues to be viewed as a significant ozone- depleting chemical. ...

... Ceresт?? bright spots show unexpected changes . ... CERES | ... Observations made using the HARPS spectrograph at the European Southern Observatory s (ESO) La Silla Observatory in Chile have revealed unexpected changes in the bright spots on the dwarf planet Ceres. Although Ceres appears as little more than a point of light from Earth, careful study of its light shows not only the changes expected as Ceres rotates, but also that the spots brighten during the day and also show other variations. ...

... We compare our results with the GRANAT X-ray observations of the Galactic center (Churazov et al. ... It is instructive to compare our results for the Galactic center starburst with what might be expected for a continuous star formation, with the average rate characteristic for the whole Galaxy. For this continuous star formation model, we would expect to observe in the region of around the Galactic center about 10% of the total number of X-ray sources in the Galaxy. ...
