The procedure simply observes ON your source for x minutes and then takes a `blank sky' observation OFF your source for the same amount of time and tracking the same azimuth and zenith angle range. ... Typically, observing times are kept to within 5 minutes (with 5 minutes as the most efficient, and therefore default, choice). ... If your scans are for 5 minutes or less, your wait time should be set to 1 minute (the default setting). ... A 5 minute ON/OFF + 10s CAL takes 11.3 minutes. ...

... The derived position here agrees with the position from recent ATCA observations, RA=15h 01m 34.74s, Dec=39 18 39.2" (Tasker, private communication) which found the source unresolved. Because of the relatively large position offset, the reality of the fainter component 0.12" to the west is somewhat in doubt. However, the ATCA centroid position is offset by 0.3" to the south-east of the VLBA position, suggesting that the faint component may be part of more extended structure. ...

For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...
