Diameter of Sun Varies as Spots Astronomers Find
Gases Unable to Escape Cause Increase of Size With Decrease in Fissures
of Rome
By Siguria Gabriella Armellini,
Director of the Royal Observatory
From time to time, spots are visible on the sun and they are sometimes large as to be seen by the unified eyes, with the help of courses, of smoked glass. When examined through powerful telescopes these spots appear as holes or fixtures in the hispicious surface.
Statistics have shown that, the units surface uptake to have the larger number of spots once in every hour. The decrease in the gradual decrease in the number, frequency and size of the spots is most at present. The spots are almost at
Work Difficult
It has now been ocorreted, at the Astronomical Observatory of Rome, situated on the Capitol, that the dimension of the sun varies in proportion with the number and frequency of the spots.
The work of acquainting this fact has been long and difficult, because the variations are slight, and take place over long periods. Thus, be careful not to confuse the several periods of 11 years had to close, handling on the result of their investigations as a loyenne to those who might to come after them. Every day, at midnight, for the last 60 years, an astronomical diameter is measured in the Romus observatory, by throwing the image of the sun or a white screen, through an astronomical telescope which reaches with a diameter of about one meter.
Several Measurements Made
Measurements are carried out by means of a network of thin cables and in order to secure perfect accuracy, are taken separately by three different instruments, each of whom have been carefully collected and investigated, have combined the fact to be established that the diameter of the sun varies in every peribol of 11 years, but that the sun is at its greatest diameter a little before the greatest diameter a little before the greatest number of hours when the sun is fully covered with spots, its diameter is smaller than when it is free from such spots.
As previously stated, the spots appear to be holes on the same 'surface'. It is therefore unimplemented that in the absence of spots, the passes which contain holes on the sun can not find an exit, with the result that the diameter increases.

Ice on Wings Menaces Trans-Oceanic Flights; Preventives Sough
homas Carroll Gives Expert Analysis of Phenomena as Observed
Washington, March 29. — Man's conquest of the air has met many obstacles and from many unlooked for challenges and from many unlooked for chief test pilot, National Advisory Committee for Aeronautics. The formation of ice on the wings and other parts of an airplane in flight is one engaging serious attention just now.
It is not a new phenomenon. It has definitely reported in the Air Mail seven years ago, but it has always been unexplained by frock conditions. For it is unusual at freezing temperatures, and it has been said to be impossible. But it has and it does not.
This unfriendly gesture of nature is a very serious hazard in flight. Colonel Lindbergh has called it the greatest.
The conditions which provide the phenomenon are not understood. It is similar to the formation of sleep on trees but that does not by any means appear to be the whole story. Attempts at reproducing the ice cream would also require further mystery is supplied in the fact that it has not been reported by others.

The accumulation of the lee, one it starts to form, becomes distribution over the front edges of the wings, of the propeller in turn. The propeller could form on the blade of the propeller running at fifteen hundred revolutions per minute has been so cooled that an impossibility, but it is now clearly established, but undoubtedly and we coded fact.
Ice in bee and even a thin coat lying on an airplane can provide a considerable additional weight to overload the plane. But two other ways in which the lee forces the airplane are the lee forms and the lee forms it mushrooms out along the front edges and forms bolts and bungs along the forward part of the wings. In the first place this greatly increases the air resistance requiring more thrust, and in the second the proper shape of the wing contour which provides the lift force is certainly interfered with. These with the added weight of the lee, raise the plane down lower and finally force it to the ground.
Many remedies and preventives have been suggested and have been tried. How effective will he be?
difficult be state since it seems almost impossible to try them out, so illustr are the conditions which produce the effect.
Some possibly promising remedies:
Simar. The airplane with grease or oil so that it will shed the ice before it sets. Another similar method, the gel, which is a chemical which will produce a solution with a lower freezing point.
Most promising is the proposition to pipe the exhaust through the wings to keep them warm. This may be effective since it is believed that only a small rise in temperature will prevent the ice.
