This false-color image of the sun was made about 48 hours before the solstice in the light of soft (lower energy) X-rays by a telescope on board the space-based Yohkho solar observatory . The normally bright, visible solar surface or photosphere appears dark in X-ray light while active regions in the solar corona which lie above the photosphere are particularly X-ray bright. ...

Position Switching Separation Tolerance with Arecibo in L-Band Travis McIntyre The University of New Mexico July 2010 Revised December 2013 Abstract The blocked telescope aperture at Arecibo creates standing waves in the bandpass around 1MHz. ... Test observations with Arecibo in L-Band show that position switching effectively removes standing waves for separations of one half FWHM or less. Standing waves remain for separations of one FWHM, increasing the rms of the baseline by 20%. ...

Science Observatory Branch Report SOB-93-12-06 A determination of the pointing history during FOS scans of Mars Colin Cox and Matt Lallo December 1993 We have used pointing software, developed earlier for a comparison with the PASS software, to analyze scans of Mars performed at intervals since June 1992. ... For these sets of data the V2 V3 positions are those of the Faint Object Spectrograph's paired apertures as recorded in the Science Instrument Aperture File in the Project Data Base. ...

... Astronomers have taken the best photos ever of a star that has lost most of its material to a vampire star! This picture shows the positions of a large star (shown in red) and the vampire star (shown in blue) in photos taken about 1.5 months apart, as they orbit around a common point. ... The new observations show that the larger star is a bit smaller than astronomers had previously thought. ... The smaller companion star then just eats whatever comes its way like a friendly vampire! ...

Sling and Pick of Loft Extension: December 6, 1999 . ... The crane is brought into position to begin "picking" the loft into place at the enclosure. It will take 8 "picks" to move it into place. ... The "braintrust" begins final deliberations on moving the loft into position. The extension is moved forward by the crane approximately 16 feet and then the blocks are moved and the crane is repositioned for another pick. The whole process takes approximately 15-20 minutes each time. ...

. I will summarise the work I have done here at RSAA on transiting exoplanets, particularly with regard to the HATSouth discoveries. I will then discuss some of the exoplanet projects I will be involved with in my new position at Geneva Observatory - primarily NGTS, CHEOPS, ESPRESSO, TESS and PLATO.
