I-GALFA View of a Galactic Tangent Region . ... Image featured in NAIC Newsletter #46 . I-GALFA image of hydrogen gas in a tangent region outside the Sagittarius arm. ... Because we are viewing this gas in a direction closely aligned with (tangent to) its orbital motion, it appears to be moving away from us (we are orbiting the Galactic center with a similar speed, but our own motion in a different direction). ... The gas near 60 degrees longitude is being viewed tangent to its orbital motion. ...

The power specta for line intensities of several lines formed in the upper transition region around 100,000 to 250,000K are presented. A period of ~5 min. is clearly present in lines due to O III, O IV and O V. In one dataset a period approaching 10 min. is present for ~10 min. ... In all datasets examined, there is excess power below 1mHz everywhere along the slit, although the observed periods do not always come from the most intense regions. ... In all regions, the 5.0mHz power peak is smaller. ...

... I present results from several seasons of photometric observations of X--ray sources in the Orion OB1a and OB1b star formation regions. The initial goal was to measure the rotational periods of several dozen pre--main sequence (PMS) stars. ... Infrared and optical data confirm that 90% of the X--ray sources are PMS and about 10% of the PMS stars may have disks. ... I find rotation periods for five stars at confidence of greater than 99.9/ greater than 99/ at much lower confidence. ...
